The stationary cap has input and exit passages. A filter cap has a threaded exterior surface removably received in the threaded aperture. A flow discharge passage has a lower end positioned within the filter. The flow discharge passage has an upper end coupled to the exit passage. An annular flow cavity is provided between the flow discharge passage and the exit passage.
Abstract:
The filter device (10) is provided with a drain device (50) provided with a main body (51) and a plug (60). The main body (51) has a first opening (51a) which communicates to the outer side of a housing (20), a second opening (51b) which communicates with an inner side (42a) of a filter element (40), and a third opening (56) which communicates with a first channel (51c) communicating to the first opening (51a) and the second opening (51b) and a space (B) between the filter element (40) and the housing (20). The plug (60) is held within the first channel (51c), and is movable between a first position (P1) at which fluid is not discharged from the housing (20), and a second position (P2) at which fluid is discharged from the housing (20). The plug (60) is provided with a second channel (65) that communicates with the first channel (51c) and communicates with the outer side of the housing (20) when in the second position (P2).
Abstract:
A filter assembly for filtering water from an external source, the filter assembly having a manifold assembly and a filter cartridge. The filter cartridge includes a cartridge engagement means while the manifold includes a manifold engagement means. The cartridge engagement means and manifold engagement means cooperatively interfacing for removable attachment of the filter cartridge to the manifold assembly. The cartridge engagement means and manifold engagement means oriented in a retaining relation during removal of the cartridge filter from the manifold assembly such that any entrained pressure within the cartridge filter is vented while the cartridge engagement means and manifold engagement means are in the retaining relation.
Abstract:
A filtration assembly is provided for a liquid flowing in an engine or hydraulic equipment, of the type including a body with a head on top thereof, and a cylindrical member for holding a filtration cartridge containing a filtration medium defined by an upper flange and a lower flange. The upper flange is coupled to the head by a first longitudinal retainer. The cartridge includes a second longitudinal retainer interacting with the body. The first retainer having a longitudinal tensile strength lower than the longitudinal tensile strength of the second retainer.
Abstract:
A water treatment apparatus includes a frame and a plurality of connecting accessories, manifolds and filter cartridges. Each of the connecting accessories includes a seat ring fixed on the frame and a communicating pipe coaxially received in the seat ring. The seat rings together with the communicating pipes are spaced at a distance from one another. Each of the manifolds is suspended between adjacent two of the connecting accessories and has inlet and outlet ports at opposite ends. The inlet and outlet ports of each of the manifolds are rotatably and coaxially received in adjacent the seat rings respectively with their exterior walls in contact with inner walls of adjacent the seat rings and their interior walls in contact with outer walls of adjacent the communicating pipes. Additionally, the filter cartridges are detachably joined to the manifolds respectively.

Abstract:
A rotary valve spindle for flow control in the head of a filter includes a unitary dual function seal that is carried by the spindle and seals against the inner surface of the filter head during spindle rotation between flow and no-flow positions. The dual function seal greatly simplifies manufacture and assembly of the valve.
Abstract:
A system comprising a fluid treatment assembly and means for feeding the assembly with fluid to be treated and receiving treated fluid, comprising a structure (12) on which the assembly is adapted to be removably mounted, to interengage complementary connectors thereof with each other, is characterized in that it includes cooperating functional surfaces (25) formed on the assembly and the structure (12) so that they can enter into mutual contact to immobilize the assembly against movement in translation and keep the connectors interengaged with each other when the assembly is mounted on the structure (12) and to allow the assembly to be released in order to remove it from the structure (12) by exerting on the assembly an action limited to tilting it relative to the structure (12) and guided by the connectors interengaged with each other.
Abstract:
An assembly method and related subassembly for a water filter element in the housing of a replaceable filter cartridge provides for filter element insertion into the open bottom end of the housing and subsequent attachment of a retaining ring to the upper end of the element such that the element is secured against vertical drop-out until the bottom end of the cartridge can be enclosed with an end cap. The method and subassembly are particularly well adapted to cartridges in which the lower end cap is attached by spin welding. The enclosing end cap may also be provided with end rings to enhance the user's grip in cartridge installation and removal. The end rings may also be color coded for each of cartridge identification and matching to the filter head.
Abstract:
Filter device (10) is provided with a head (20), a filter element (40), and a housing (30). The head (20) is provided with an inlet (24) which is attached to a hydraulic circuit (5), and into which flows the operating oil (L1) that is to be filtered. The filter element (40) filters the operating oil (L1) that is to be filtered. The housing (30) has an opening (30b) through which the filter element (40) passes, and which holds the filter element (40) inside it. The filter element (40) is provided with an element main body (48), and an element pressing part (47). The element pressing part (47) is provided to the element main body (48). The element pressing part (47) is provided with a contact part (53) that can be shifted toward or away from the inner surface (30a) of the housing (30). A groove (35) that holds the contact part (53) is provided to the housing (30). The contact part (53) can be shifted until it comes out of the groove (35).
