A filtration system having an undulated interlocking housing-endplate interface geometry is described. In the filtration system, a filter element endplate and a filter housing component (e.g., a shell housing, a filter mounting head, etc.) meet at an interface. The filter housing component includes an undulating or repeating pattern that meshes with a matching undulating or repeating pattern on the endplate of the filter element. The undulating or repeating pattern prevents the filter element from freely rotating with respect to the filter housing component of the filtration system.

Undulated interlocking housing-endplate interface geometry

A filter apparatus is described that has a torque limiting device, which may be a clutch mechanism, and which provides a protective function for a filter, so as to protect a filter from being over tightened and to thereby prevent damage to filter components. The clutch mechanism can also eliminate or reduce the need for torque measurement of certain filter components. The clutch mechanism can be located on one of the fluid filter, a filter head which engages the fluid filter, or a combination of both the fluid filter and the filter head.

Filter apparatus with torque limiting mechanism

A filter element for fuel, oil or other engine fluids, with an endplate that is designed to create flow paths for both clean and dirty regions. The filter element is part of a spin-on filter that is attachable to a filter head in an engine and that filters fuel, oil or other engine fluids. A pre-fill cap can be integrally incorporated onto the endplate to permit pre-filling and installation without removing components.

Filter element endplate defining inflow and outflow flow paths

A fluid filter device is described, where a flow attachment member provides a unique interface between the filtering element and a filter head. The fluid filter described herein generally provides a flow structure that is localized and sealed. The flow attachment member is configured to communicate fluid into and out of the fluid filter, and is configured to localize fluid flow both into and out of the fluid filter within a separating structure of the flow attachment member. The flow attachment member further includes a seal structure configured to substantially prevent or at least confine leakage to a localized area away from proximity of the edges of the housing. A composite filter head is described that has integrally molded inlet and outlet fittings.

Filter with localized flow attachment and filter head

A filter within a filter cartridge design is described that includes a sealing structure on an endplate of an outer filter element. Generally, the sealing structure includes an annular flange on the endplate that can directly seal against an interior surface of a housing when the filter cartridge is assembled for use. During filtration, the annular flange prevents a working fluid from bypassing the outer filter element. The sealing flange can seal with the housing in a press fit engagement.
