A modular hydraulic device comprising: a housing having a receptacle having a first open end, a second end and a first port, the first port for facilitating an ingress and an egress of hydraulic fluid with respect to the housing; a sleeve configured to be received in the first open end and abut the second end; and an end cap for closing the first open end once the sleeve is inserted in the receptacle; the sleeve having: a body having a fourth lan (L4) positioned in the body for aligning with first port; a main cylinder for holding a main piston for reciprocation about a reciprocation axis; and a first bore portion fluidly coupled to the first lan, the first bore portion for receiving the ingress of the hydraulic fluid and for outputting the egress of the hydraulic fluid; wherein once assembled the main piston is coupled to a cam for facilitating said reciprocation.

The present invention aims at providing a new electro-hydraulic control terminal adopting modularized and configured cartridge valve RHCV. It has obvious advantages of hybrid combination and flexible customization when RHCV is applied in the independent control terminals based on “single loop resistance” to control hydraulic actuators including distributed cylinders and motors. It can follow the rules that functional diversities as many as possible can be achieved through technical diversities as few as possible, thus producing a new generation of electro-hydraulic product family and platform to meet the needs of customers.

A food article defect removal apparatus includes a manifold that defines one or more chambers for holding pressurized fluid. First channels extend from a first side of the manifold into fluid communication with the chambers. Second channels extend from the first side of the manifold to a second side of the manifold. Valves selectively connect corresponding first channels and second channels together to dispense the pressurized fluid from the manifold. The manifold can have an exterior wall that at least partially defines a first chamber and a second chamber, with an interior wall disposed between the first chamber and the second chamber. The interior wall can define the second channels. The valves can be included with a valve assembly, which includes a driver operably coupled with the valves. The valves can be pluggably coupled with the driver.

A connecting apparatus connects to a main component (10) having a plurality of mutually adjacent fluid passage points (P1, P2, P3, Pn . . . Px). The connecting apparatus has a main body (12) controlling a fluid flow by a valve. A plurality of further fluid passage points (P1, P2, P3, Pn . . . Px) can be connected to each other in a fluid-conducting manner via the functional component (14) with assignable fluid passage points in the main component (10). One shut-off part, which shuts off the respective fluid passage point (P2, P3, Pn . . . Px1) in the main component (10) and/or in the fluid passage point remains unaffected by the functional component (14). In each case a fluid-conducting connection line (30, 32) is inside the main body (12) between the further fluid passage points (P1, P2, P3, Pn . . . Px) and the functional component (14) and can be shut off by a separate shut-off part, as long as the associated connection to the functional component (14) remains unused.
