A valve arrangement includes a valve shaft having a fluid flow bore, and valve gear projections or teeth projecting from the valve shaft, constructed and arranged to receive a force to rotate the valve shaft. The valve arrangement can be used in a filter assembly having cartridge projections such as gear teeth to mesh with the teeth on the valve gear.

A filter cartridge (30) comprising a substantially tubular filter wall (33) and a support plate (32) fixed to an end of the filter wall (33), where the support plate (32) comprises a hooking body (34, 2120) rising from a surface of the support plate (32) opposite the filter wall (30) and defining a profiled surface (3410,3411;2130,2131) substantially perpendicular to the central axis of the filter wall (33) and defining at least two corners (3412,3413;2132,2133) proximal to the central axis, which exhibit different distances from the central axis of the filter wall.

A multi-component end cap is provided. The multiple components combine to form one or more seal carriers where each seal carrier is formed in part by at least two different ones of the components. Methods of manufacturing an end cap having multiple components are also provided.

To move a filter along a manifold assembly the filter may be seated on a moveable shuttle assembly. Seating the filter on the shuttle assembly may include mating a key portion on the filter with a key portion on the shuttle assembly, each key portion corresponding to a filtration characteristic of the filter. The shuttle assembly and the seated filter may then be moved between a first position, wherein the key portions of the filter and the shuttle assembly are mated to one another and first and second fittings of the filter are spaced from first and second fittings of the manifold assembly, and a second position, wherein the key portions of the filter and the shuttle assembly are mated to one another and the first and second fittings of the filter sealingly engage the first and second fittings of the manifold assembly.

The present invention relates to operation of air-oil separators and oil filters used in systems requiring oil separation and filtration on a single block. In other words, the present invention discloses an oil separation and filtration system having an air-oil separator and an oil filter.

A filter device with a removable termination part (81; 82) and a housing (3) that receives a replaceable filter element (5) having two end caps (25,47). Between the end caps, a filter material (12) extends. A positioning device (65) is arranged between the termination part (81; 82) and one end cap (47). The positioning device positions the filter element (5) within the housing (3), at least when viewed in the circumferential direction of the filter element, in interaction with at least one corresponding positioning element (71) of the end cap (47).

A no filter no run bidirectional pin element is disclosed. A shell housing is removably coupled to a filtration housing, a removable no filter no run attachment, and a filter element. The filter element comprises a filtration media and a bidirectional pin element. The bidirectional pin element comprises a center tube formed as a single piece with a bidirectional pin. The installation of the filter element and the shell housing into the filtration system results in the bidirectional pin entering a pin aperture of the removable no filter no run attachment and the bidirectional pin preventing the operative engagement of a blocking element with a divider inside the no filter no run attachment.

The filter device includes a case, an element, and a water separator. The case accommodates the element and the water separator. The element removes solid particulates from the fuel. The element can be replaced by opening the case. The water separator removes water content from the fuel. The water separator is held in the case. The water separator is movable relative to the case. The water separator is movable within a movable range. The element and the water separator are provided with a passage connecting member for connecting a fuel passages.

A water filter assembly is provided, including a filter head including a filter manifold in fluid communication with an existing water line, a head housing connected to the manifold and including landings, an elongate key member depending from a portion of the filter head, and a filter cartridge including a filter housing constructed and arranged to retain a supply of filter media, a filter closure attached to an upper end of the filter housing and having at least an inlet port and an outlet port, the closure configured for engaging the landings of the head housing and also having a recess constructed and arranged to matingly and slidingly accommodate the key member so that, upon engaging the filter head, the filter cartridge is in alignment with the filter head.

A filter assembly is disclosed comprising a filter cartridge, a filter housing end part, and a filter housing main part, said filter housing main part being adapted for receiving said filter cartridge and for being connected to the housing end part by screwing, wherein said filter housing main part comprises a first longitudinal axis and a main opening, said main opening being defined by a first end portion, said first end portion comprising an upper, interrupted rim and a first threaded portion arranged below said upper rim; said first end portion comprising a recess arrangement comprising one or more axially extending recesses, said one or more axially extending recesses at least partially interrupting said first threaded portion; said filter cartridge comprises a second longitudinal axis and a first end cap, said first end cap comprising a central portion and a radial extension arrangement comprising one or more radial extensions extending radially away from said central portion; and wherein said radial extension arrangement is adapted for being receivable or received by said recess arrangement; and associated cartridges.
