[0137] 1. The new electro-hydraulic control terminal adopting a new kind of modularized and configured cartridge valve RHCV comprises two kinds of control resistance of different structures and combinational feature, which are compact two-way cartridge valves (MINISO CV, CV as abbreviation) and modularized and configured screw-in cartridge valves (MINISO SCV, SCV as abbreviation). The hybrid combination of two kinds of control resistance is used to control two reversible cavities (A, B) of controllable hydraulic actuators (Z representative of cylinder, M representative of motor). Two modularized and configured screw-in cartridge valves (SCV1, SCV2) are used as oil-input resistance, and two compact two-way cartridge valves (CV1, CV2) are used as oil-output resistance. They together with the integrated functional valve body characteristic of the four-way functional and connectional feature constitute the basic type electro-hydraulic control terminal. Integrated functional valve body has two forms BL and BH. Two compact two-way cartridge valves (CV1, CV2) are used as oil-output resistance arranged on the same side of the same face. And two modularized and configured screw-in cartridge valves (SCV1, SCV2) are used as oil-input resistance having different arrangements. They constitute two kinds of integrated functional valve body (BL, BH) with different internal mounting holes (CVH, SCVH) and layout of pilot control ports. In terms of BL valve body, two modularized and configured screw-in cartridge valves are arranged on the same side of the same face. In terms of BH valve body, two modularized and configured screw-in cartridge valves are arranged on the opposite side of the opposite face (see FIGS. 1A, 1B, 1C, 1D, 3A, 3B, 3C, 3D). Four main stages of poppet valve (CVI1, CVI2; SCVI1 SCVI2) are controlled by hybrid self-supplied pilot control network consisting of PV1 and PV2, which are pilot solenoid valve, check valve AV, combined plug PL on the combinational flange control cover plates CVC1, CVC2. Self-supplied oil Pc is imported by the control port X on the cover plate of compact two-way cartridge valve, pilot control oil is connected with oil-output port Tc through the control port Y, self-supplied oil Pc enters in the control cavity of main stage of poppet valve CVI1, CVI2 through control port a on the combinational flange control cover plates; through control port Z1 and Z2, control port S3 of modularized and configured screw-in cartridge valve SCV1, SCV2 arranged on the same side of the same face or on the opposite side of the opposite face is connected vertically. Thus four-way circuit technological scheme (see FIGS. 2A, 2C, 2D, 2E, 2F, 2G, 2H) based on regular layout of BL, BH is formed. According to different requirements of accessories for connection, detection and communication of BL, BH, independent and integrated electro-hydraulic control terminal LEM (FIGS. 1A, 1B) and HEM (FIGS. 1C, 1D) with different shapes and same supply chain characteristic with four controllable main ports P, T, A, B and multiple auxiliary ports are formed.

The pilot control circuits (PC in FIGS. 2A, 2B, 2D, 2E, 2F, 2F, 2G, 2H) consists of pilot control elements and accessories installed in the screw adaptor SCVC1, SCVC2. The basic four-way resistance circuit with two kinds of hybrid resistance comprises power level circuit MC and pilot control circuit PC. The basic four-way resistance circuit is used to control two reversible controlled cavities A, B of double-acting hydraulic actuators Z, M. The connection and combination between power level circuit and pilot control circuit are modularized and decomposable combination. According to 4/4 circuit LEM and HEM of basic electro-hydraulic control terminal in claimed rights 1 and 2 and the setup of overall solution, the new principle scheme of circuit of independent and integrated electro-hydraulic control terminal with four controllable main ports P, T, A, B and multiple auxiliary ports Pc, Tc, Mc including accessories for connection, detection and communication is formed.

The symbol of main stage of poppet valve is commonly shared by compact two-way cartridge valve and modularized and configured screw-in cartridge valve. But the screw adaptor of modularized and configured screw-in cartridge valve is newly composed. The new circuit schematic diagram shows internal hybrid mounting holes and pilot control ports of integrated functional valve body except different body types and external connection features. New circuit principle diagram is also listed with two schematic diagrams of “single component circuit” (see FIGS. 2C, 2G) and new position function symbols (2D, 2H) for comparison. Intelligent design and analysis by using the computer can be applied to the compact electro-hydraulic control terminal and the whole process of supply chain management.

[0139] 3. In terms of integrated functional valve body BL, BH (see FIGS. 3A, 3B, 3C, 3D, 1A, 1B, 1C, 1D) of electro-hydraulic control terminal adopting a new kind of modularized and configured. cartridge valve, within the valve body (BL, BH) they have one arrangement that two mounting holes of compact two-way cartridge valves are on the same side of the same face (CVH1, CVH2), and two mounting holes of modularized and configured screw-in cartridge valves are arranged differently (SCVH1, SCVH2). According to the rules (new principle scheme of circuit of electro-hydraulic control terminal LEM, HEM, FIGS. 2A, 2B, 2C, 2D, 2E, 2F, 2G, 2H), in terms of BL valve body, two modularized and configured screw-in cartridge valves (SCVH1, SCVH2 are arranged on the same side of the same face (F1) adjacent to that of compact two-way cartridge valves (CVH1, CVH2). The BL internal mounting holes and pilot port layout feature can be referred to FIG. 3B. In terms of BH valve body, two modularized and configured screw-in cartridge valves (SCVH1, SCVH2) are arranged on the opposite side of the opposite face (F2, F4) adjacent to that of compact two-way cartridge valves (CVH1, CVH2). The BH internal mounting holes and pilot port layout feature can be referred to FIG. 3D. Self-supplied oil Pc is imported by the control port X on the mounting face (CVF1, CVF2, FIGS. 3A, 3B, 3C, 3D) of cover plate of compact two-way cartridge valve, pilot control oil is connected with oil-output port Tc through the control port Y, self-supplied oil Pc enters in the control cavity main stage of poppet valve CVI1, CVI2 through control port a on the combinational flange control cover plates; through control port Z1 and Z2, control port S3 of modularized and configured screw-in cartridge valve SCV1, SCV2 arranged on the same side of the same face or on the opposite side of the opposite face is connected vertically. According to different requirements of accessories for connection, detection and communication of BL, BH, integrated functional valve body of regular hexahedral shape characteristic with four controllable main ports P, T, A, B and multiple auxiliary ports are formed (FIGS. 3A, 3C).

[0140] 4. The pilot control ports of integrated functional valve body BL, BH have the hybrid connecting feature of “one carrier controls more than one assembly”. It can be seen in the FIG. 4 (only connecting path between CV1 and SCV1 shown), self-supplied oil Pc after being compared and chosen within the valve body is imported by the control port X on the cover plate of compact two-way cartridge valve, pilot control oil is connected with oil-output port Tc through the control port Y, self-supplied oil Pc enters in the control cavity of main stage CVI1 of compact two-way cartridge valve through control port a on the combinational flange control cover plates; through control port Z1 and Z2, control port S3 of modularized and configured screw-in cartridge valve (only connecting path between CV1 and SCV1 shown) arranged on the same side of the same face or on the opposite side of the opposite face is connected vertically. The combined flange cover plates CVC1 (only CVCB, PIH, PVF shown) is used as main carrier of pilot control to realize “one carrier controls two assemblies” in terms of modularized and configured screw-in cartridge valve and compact two-way cartridge valve, which is an innovation to the traditional cartridge valves and plays an important role in the miniaturization of electro-hydraulic control terminal LEM and HEM.

[0141] 5. The basic integrated functional valve body of new electro-hydraulic control terminal adopting a new kind of modularized and configured cartridge valve RHCV has two mounting holes of compact two-way cartridge valves and its pilot control ports, two mounting holes of modularized and configured screw-in cartridge valves and its pilot control ports.

The integrated functional valve body adopts the margin design in layout of overall design and main structure. When the combination, function, specifications, quantity and local circuit scheme belonging to main stage of poppet valve and mounting holes of two cartridge valves change, even when the pilot control components and the corresponding pilot control ports change, it can make sure that existing margin of basic integrated functional valve body can be made use of. Personalization adaptability for a variant design can be remained by the prerequisite that layout of overall design and main structure are unchanged (see FIG. 5). When four mounting holes of basic: integrated functional valve body BL and BH with hexahedral shape are symmetric (FIGS. 1A, 1B, 1C, 1D and 3A, 3B, 3C, 3D), the margin design of mounting face with main functional structure and connection feature is adopted. There is a specialized design about the layout of F1-main functional mounting face of BL for the mounting holes of compact two-way cartridge valve and mounting face of combined flange cover plate, the layout of F5-main functional mounting face of BH. Besides, there is a specialized design about the layout of F5-main functional mounting face of BL for the mounting holes of modularized and configured screw-in cartridge valve, the layout of F2 and F3-main functional mounting face of BH. Because the above-mentioned mounting face not only influences the layout of main functional structure and connection feature, but also influences the margin design with different installation and connection features, it has a significant impact on the variant design. Other non-main functional structure and connection feature in the valve body with hexahedral shape influence the different installation and connection layout design, which can be seen in the FIGS. 15, 17 in 6A. Especially for many marks with 4-d in the attached figures, margin design for integrated functional valve body of basic BL and BH can be indicated through the setting of flange installation connecting face which can be directly or nearly connected with cylinders. Based on the symmetric layout of valve body BL and BH, variant design and local change can he implemented flexibly for the asymmetric layout. The overall layout and its shape design can be still maintained.

It is a hydraulic equipment with the function of complete 3/4 complicated circuit and the main ports P, A, B, T. In the FIGS. 17(a) and (b), 4WE belongs to the same 3/4 directional valve which is single component. What are described in FIG. (c)-(j) are some typical electro-hydraulic control terminal LEM and HEM. For the sake of comparison, entities have the same proportion. In terms of shape, volume and weight, electro-hydraulic control terminal (EM) indicated in FIG. (c)-(j) is the same with 4WE “single component”. Only slight differences exist, compared with FIG.(a), it is 1/2-1/3 of those of IH, EM terminal has complex function of 4/4, which can he seen in 2A, 2B, 2C, 2D, 2E, 2F, 2G, 2H.

By the contrast, power-to-weight ratio of LEM, HEM is only about 1/2-1/3 of IR, and has significantly compact, lightweight, miniaturized and flexible and diversified customized features, thus fundamentally subverting the traditional supply chain and the management pattern of “single component loop” manifolds. It has the advantage of high efficiency, low energy consumption and total cost is decreased.
