摘要:
A fuel tank filter (20) connectible to a fuel pump (12) mounted inside of a fuel tank (10) is disclosed. The filter (20) includes filtration material forming an envelope (22), a separator (30) inside the envelope and a spring (50) attached to the separator (20) in a manner such that the spring (50) biases the separator (30) to hold the envelope (22) towards the bottom of the fuel tank (10).
摘要:
A process for producing hermetically sealed filters (10) is disclosed. The process includes the steps of providing thermoplastic base (20) and top (30) filter parts and a section of filtration media (50), sandwiching the media (50) between sections of the base and top filter parts (20, 30) under a compressive force, applying a rapidly repetitive force to at least one of the filter parts (30) to cause movement between the parts and frictional welding of the parts, maintaining the compressive force after frictional welding to allow the melted portion of the parts (20, 30) to solidify and thereby form a fluid seal at the junction of the filter parts and at the junctions of the filtration media (50) and each of the base and top filter parts (20, 30). In one embodiment, the junction between the filter parts is the periphery of an automatic transmission filter, and the junction is hermetically sealed. A hermetically sealed automatic transmission filter is also disclosed.

A filter ring includes a first filter member including a first end portion and a second filter member including a second end portion. The filter ring also includes at least one snap latch mechanism for detachably engaging the first end portion with the second end portion such that the first and second filter members cooperate to define a generally annular shape having a central opening. The first end portion includes at least one key configured to be positioned within at least one keyway defined by the second end portion for inhibiting disengagement of the snap latch mechanism when the snap latch mechanism is detachably engaging the first end portion with the second end portion.
摘要:
A method of making a head for a semisolid product dispenser, such as a gel deodorant dispenser, comprises the steps of: providing a piece of porous media (60) having a desired shape with a perimeter and openings through the media in the area inside of the perimeter, compressing at least the portion of the media inside of the perimeter between two parts of a hard tool so as to crush the media, thereby reducing the size of the openings and affixing the porous media to a head frame to form the semisolid product dispenser head.
摘要:
A valve (18) includes an inlet (12) and outlet (14) housing, a flexible one-way valve (18), and a collar (30). The flexible valve (18) is locked between the housings (12, 14). The collar (30) is attached to the inlet housing (12) and extends into the flexible valve (18). As fluid flows through the valve (18), the collar (30) supports the flexible valve (18) and prevents collapse due to back flow pressure.
摘要:
A non-needle access device (10) includes a housing (12) having a fluid pathway and an inner chamber (34). A biased plunger (16) is disposed within the inner chamber (34), movable between a first position, and a second position. A main seal (32) seals the inner chamber (34) from the fluid pathway. A vent (20) between the inner chamber (34), the outside of the housing (12) allows air to pass out of and into the inner chamber (34) when the plunger (16) is moved between the first and the second positions.
摘要:
A sump filter assembly (110) wherein a filter element (140) that may or may not be removably disposed in a filter housing (120) is sealingly engaged with the filter housing by way of a sealing member (180) to separate the filter housing cavity between dirty and clean spaces. The filter element (140) is provided with filtration material (170) with a portion thereof embedded in the filter element, the filter element is further provided with a sealing member retaining shoulder (144) to ensure proper placement of the sealing member (180) in the assembly, with the sealing member being an O-ring (180) or gasket member, among other things.
