    Abstract: A fluid filter with a housing, a fluid inlet, a fluid outlet, a central standpipe which forms the fluid outlet, a filter insert which is plugged onto the standpipe, and a valve unit which is arranged on the outer circumference of the standpipe. The valve unit has a valve seat, a valve body which can be moved in the axial direction of the standpipe, a valve spring which is guided on the standpipe and biases the valve body in the valve closing direction, and a valve spring support which is attached to the standpipe. The valve body is made of an elastomer body, and an intermediate valve ring which is guided on the standpipe in an axially movable manner, is arranged between the valve spring and the valve body.

    Abstract: A filter having a filter housing, an inlet for liquid to be filtered and an outlet for filtered liquid. An exchangeable filter insert separates an unfiltered side and a filtered side of the filter. A filter bypass valve has a valve seat and a valve body guided so as to be movable relative to the valve seat and preloaded in the closing direction. The valve seat is fixed to the filter. The valve body is guided in the filter so as to be fixed to the filter. A spring that preloads the valve body in the closing direction is guided in the filter so as to be fixed to the filter. The filter insert has a spring support that, in the state in which the insert is placed into the filter housing, supports and pre-stresses the spring at its end facing away from the valve body.

    Abstract: A fluid filter comprises a housing, a fluid inlet and a fluid outlet, a filter element separating a raw side and a clean side from one another, and a valve unit. The valve unit comprises a valve plate arranged concentrically in the housing and having the shape of a circular ring disc, having valve openings and a flexible circular-ring-disc-shaped valve membrane arranged on the valve plate. The filter element comprises an axially protruding pressure-exerting ring shaped as a circumferential annular collar on the end face thereof facing the valve unit when installed. When installed in the housing, the filter element, with an end face of the pressure-exerting ring, presses the valve membrane axially onto the valve plate. The valve membrane, with the membrane region thereof pressed by the pressure-exerting ring onto the valve plate, forms a seal separating the raw side from the clean side of the fluid filter.

    Abstract: A filter cartridge configured to be removably inserted into a space of a filter housing that has a housing socket and a housing cover with a sealing surface facing inwards. The filter cartridge has a filter element forming a fluid channel with a longitudinal axis, a front end, and a rear end, as well as a connector element with a peripheral surface that provides for an increased filter area, if the peripheral surface includes a first ring surface and a second ring surface (which are plain bearing surfaces) and if a gasket is movably supported in a first axial position on the first ring surface, thereby enabling a translation of the gasket in a first direction to a second axial position onto the second ring surface.

    Abstract: A filter cartridge includes a filter element (forming a fluid channel with a first longitudinal axis) with a front side to which a front end cap is sealingly attached, a conduit (with rear and front ends) attached to the front end cap, and a through hole (in the front end cap) that provides a fluid communication between the channel and the conduit, to enable oil flow from the channel via the rear end of the conduit through the conduit to its front end. Pressure drop for a given oil flow rate is reduced if the conduit has a straight end section (defining a second longitudinal axis) in the vicinity of its front end. The second longitudinal axis intersects the first longitudinal axis at a single point to define a non-zero angle α between the axes.
