An oil filter assembly is disclosed for a machine, such as an internal combustion engine, that has an oil output port and an oil input port. A mounting plate is fixed with an outer enclosure. The mounting plate is further adapted to conduct oil from the machine into a peripheral portion of the outer enclosure, and then returning oil from a central portion of the outer enclosure back to the machine. Oil may pass from the peripheral portion to the central portion through a primary filter having a first porosity. A pressure-actuated valve is fixed fluidly between the portions of the outer enclosure.

A filter cartridge including catches for ejecting the filter cartridge from a filter housing as the filter cartridge and filter housing are removed from a filter base is provided. The catches are configured to engage corresponding catches of the filter base to limit axial motion of the filter cartridge as the filter cartridge and filter housing are threadedly removed from the filter base.

The present invention presents a filtration system with an integrated manifold valve. The filtration system employs only one pivotal componentthe pivoting of the manifold. The manifold valve includes a dual aperture design for a two-fold alignment scheme with the ingress and egress lines of the fluid source. The invention is free of multi-component rotary valve with internal, rotatable parts, or an activation component, such as a handle, for initiating the rotary valve, allowing the user to rotate the rotational components thereof. The reduction in moveable components in this design reduces the likelihood of failure and increases the reliability of the filtration system.

A filter cartridge endplate (12) is described herein that has an integrated flow structure. For example, the integrated flow structure has concentric flow portions disposed at a center of the endplate (12), where a separator (10) is built into the endplate (12) that separates fluid flow. The endplate (12) includes a plate with a major surface, a separator (10) that protrudes axially away from the major surface. The separator (10) includes a first flow portion (14) and a second flow portion (16), where the first flow portion (14) is disposed radially inward relative to the second flow portion (16). The first flow portion (14) includes a channel (22) and the second flow portion includes a channel (24). The respective channels (22,24) are configured to allow axial fluid flow relative to the plate, and configured to allow fluid flow that is localized toward the center of the plate (12).

A filter device for fluids with a fluid inlet (14) and a fluid outlet (24). A filter element (9) is enclosed by an end cap (21) on its lower end facing a bottom part (5) of the filter housing (1). The end cap has a passage (29) forming a fluid connection to the filter element inner filter cavity (17) and can be fixed to an element retainer (23) of the filter housing (1). The element retainer (23) includes a retaining piece (35) open towards the filter element (9) with a fluid channel (37) leading to a housing connection (24). The end cap (21) has a connecting piece (27) in the retaining piece (35). The retaining piece (35) forms an opening (43) connected to the fluid channel (37) leading to the element retainer (23). A sealing (45, 47) seals the opening from the open end of the retaining piece.

A locking-unlocking structure for guiding forward lifting of a lifting body lifted by repeating a pushing action is provided. The locking-unlocking structure includes an actuation guide unit provided at a center thereof therein with a stop groove to guide stop of a lifting body in a lifting state, having a lifting line and a falling line branching downward from the stop groove, and fixedly coupled to a fixing body, and an actuation unit comprising a lifting plate having a stop protrusion, which is mounted in the stop groove of the actuation guide unit or circulates along the lifting line and the falling line, and coupled to the lifting body movably left and right. The guide protrusion protrudes from the falling line of the actuation guide unit while being inclined downward along the falling line to block an entrance so that the stop protrusion of the lifting plate is prevented from entering the falling line when the lifting plate of the actuation unit is lifted. The guide protrusion is provided in an elastic member to be elastically actuated when the stop protrusion of the lifting plate falls along the falling line.

Disclosed is an air conversion and condensation electro-magnetization system which comprises a water production and treatment system, a power source and a control system, wherein the water production and treatment system comprises an air purification and condensation water-production system, a primary filter and storage system, and a water quality optimization system, the output end of the air purification and condensation water-production system is connected with the input end of the primary filter and storage system, and the output end of the primary filter and storage system is connected with the input end of the water quality optimization system. The air conversion and condensation electro-magnetization system can be used for producing high-quality drinking water meeting the drinking standard at reasonable costs in places where energy and electricity are available, and overcome the drinking water difficulty for remote arid areas lacking water sources.
