Abstract:
Embodiments of the present invention include systems and methods for providing a filter (100) that is sealed solely with mechanical forces. The filter may be a high pressure filter used in semiconductor manufacturing. In various embodiments, the filter includes a housing (101) with an angled end (115, 116) and a filter element (105) disposed inside the housing. The filter further includes a fluid fitting (120, 121) with an angled side. The angled side of the fitting has a different angle than the angled end of the housing. The filter also includes a compression collar (130, 131) fitted over the housing to compress the housing and the fitting. The result is a filter that may be used as a high-pressure fluid restrictor. The filter uses only mechanical seals to provide leak-proof highly filtered fluids in which impurities, contaminants and particulates are removed.

Abstract:
A spin-on filter that eliminates the use of a nut plate and reduces the number of separate components. Instead, the spin-on filter utilizes the end plate of the filter cartridge to perform a number of functions, including closing the open end of the filter shell, sealing between the dirty and clean fluid sides, sealing between the filter and the mounting head to prevent leakage outside the filter to environment, attaching the filter cartridge to the shell, and sealing the end of the filter media.

Abstract:
A filter arrangement for threadably securing to a filter head includes a housing having a surrounding wall defining an interior volume, an open mouth providing access to the interior volume and an end opposite of the open mouth. The surrounding wall has an exterior and an interior. A filter media construction is operably held within the interior volume. A sleeve, distinct from the housing, is secured to the exterior of the surrounding wall adjacent to the housing mouth and extending partially along the surrounding wall. The sleeve has an exterior and an interior. The exterior of the sleeve defines mounting threads constructed and arranged to removably mount with the filter head, when the filter arrangement is secured to the filter head. The interior of the sleeve is against the exterior of the surrounding wall. A first seal member is oriented against the sleeve to create a seal with a filter head, when the filter arrangement is secured to the filter head. A filter assembly includes a filter arrangement and a filter head. The filter arrangement is removably secured to the filter head by a threaded connection between the sleeve and the filter head. A system includes an engine utilizing a liquid and a filter assembly in fluid communication with the engine to filter the liquid.

Abstract:
The seal consists of a lid that is rotary-mounted to the filter container base (10, 100) and has a body (11, 110) with at least two stub pipes (1, 2) and an internal part (12, 120) attached to the body. In the internal part (12, 120) are formed circulation ducts (5, 6) positioned as an extension of the stub pipes (1, 2) in opened position, and at least one bypass duct (3, 30) connecting the stub pipes (1, 2) in closed position. The internal part (12, 120) is attached to the body (11, 110) using a rotary bayonet mount by rotating to closed position in which the stub pipes (1, 2) are connected by the bypass duct (3, 30), and the body (11, 110) together with the attached internal part (12, 120) is attached to the base (10, 100) using a rotate-and-lock bayonet mount. In closed position the internal part (12, 120) is attached to the base (10, 100) in a stationary manner using a longitudinal head joint formed on the joined elements, and the changing to opened position occurs by rotating the body (11, 110) in the rotate-and-lock bayonet mount.
