摘要:
A lubricating oil filter for internal combustion engines is disclosed herein. The oil filter includes a vertical housing closed at the top by a screw cover and includes a filter support rotatably mounted on the screw cover for removably supporting an annular filter element. The filter support includes a valve element at a bottom end thereof for closing an additional outlet port at the bottom of the housing when the cover and filter support are installed on the housing and for opening the additional outlet port when the cover and filter support are removed from the housing.

An oil filter for internal combustion engines is disclosed herein. The filter includes a housing with a bottom arranged below an open top and a screw-on cover threadedly engaged within the open top. The housing includes an inlet duct, a first oil discharge duct in the bottom of the housing, and a second oil discharge duct in the bottom of the housing and coaxially surrounding the first oil discharge duct. A support part is provided within the housing having a first end which is connected to the cover in an axially force-transmitting manner and a second free end inserted into the first oil discharge duct when the cover fully threadedly engaged to the open end of said housing to sealingly close the first discharge duct, and is withdrawn from the discharge duct when the cover is removed from the open end of the housing to enable discharging of oil from the housing via the first oil discharge duct. The support part supports a primary flow filter element in a lower portion of the housing and a secondary flow filter element in an upper portion of the housing and fluidly connects the primary flow filter to the second discharge duct and the secondary flow filter to the first discharge duct. The cover, the support part, the primary flow filter, and the secondary flow filter can be removed from the housing as a unit. The primary and secondary flow filters are separable from the support part for replacement.

A filter for liquids is disclosed herein. The filter includes a filter housing containing an exchangeable filter element. A support part is provided within the housing that is separable from the at least one filter element and extends at least partly centrally through the interior space of the filter element. A means is provided for releasably attaching one end of said support part to the filter housing. The housing includes first and second radial inner seals for separating a crude space surrounding an exterior of the filter element from a clean space located within interior of the filter element with the radial inner seals being mounted within the housing at the axial ends of the filter element. The filter element is folded star-shaped and sealed on the face side and provided on the inside at each of its two axial ends with a sleeve having an interior portion resting against the radial inner seals. The first radial seal includes an extension portion contained within a groove formed in the support part for separating the crude space from the clean space. An overflow valve is contained within the support part for establishing a flow connection between said crude space and said interior space when a pressure difference therebetween exceeds a predetermined value.
