    摘要： A filter element for a fluid has a filter medium arranged in annular shape about a longitudinal axis to be flowed through by the fluid to be filtered radially. A coaxial outlet socket is arranged at an end of the filter element facing upwardly in filtering operation. The coaxial outlet socket has a fluid outlet channel for filtered fluid and a venting channel that vents a clean side and/or a raw side of the filter element. The venting channel coaxially surrounds the fluid outlet channel radially and extends at least in sections thereof in axial direction. A filter system is provided with a filter head that has a fluid inlet conduit, a fluid outlet conduit for filtered fluid, and a venting conduit, wherein the filter element is suspended from the filter head.

    摘要： A water drainage device for a filter module is provided with a valve housing that has a valve bore and a valve body received at least in sections thereof in the valve bore. The water drainage device can be transferred from a closed state, in which the valve body seals in relation to a valve seat of the valve bore, into an open state, in which the valve body is lifted off the valve seat, and transferred from the open state into the closed state. The valve body, upon transfer of the water drainage device from the closed state into the open state, moves linearly along the longitudinal axis of the valve bore and away from the valve seat along or at a slant to a direction of gravity in downward direction.

    摘要： A filter element for liquid filtration has a hollow-cylindrical filter medium body and an end disk covering an end face of the filter medium body. A central cutout axially penetrates the end disk. An outflow channel for liquid to be filtered or filtered liquid is arranged at the end disk and connects to a liquid collecting space. The outflow channel extends from a radially outward wall surface of the filter medium body to the central cutout of the end disk. The outflow channel is controlled by a drainage device. A filter device with a filter housing provided with such a filter element has a drainage device that controls the outflow channel. A filter device with a drainage device having a first drainage position for draining only water and a second drainage position draining water from a water collecting space and liquid from a liquid collecting space is provided.

    摘要： A filter for filtering liquids has a housing with an inlet for liquid to be filtered and an outlet for filtered liquid. A coaxial filter element with a filter medium having an interior is arranged in the housing such that the filter element separates the inlet from the outlet. A central tube is fastened to the housing and the filter element is arranged coaxially on the central tube. An inner support body is arranged in the interior of the filter medium in a radial direction of the filter element between a radial inner circumferential side of the filter medium and the central tube. The inner support body has support webs distributed in an axial direction and in a circumferential direction of the inner support body. The support webs support the filter medium at least radially on the central tube.

    摘要： A valve device for a fuel filter module has a first fluid channel through which fuel flows only in recirculation mode of the fuel filter module and a second fluid channel through which fuel flows only outside of the recirculation mode. The first fluid channel extends inside the second fluid channel. The first and second fluid channels are coaxial to each other. A fuel filter module switchable into recirculation mode and out of recirculation mode is provided with a control valve that has a valve bore and a valve device arranged in the valve bore, wherein the valve device has a first fluid channel through which fuel flows only in recirculation mode and a second fluid channel through which fuel flows only outside of the recirculation mode. The first fluid channel extends inside the second fluid channel, and the first and second fluid channels are coaxial to each other.

    摘要： A sealing device (24) of a filter system (10) for filtering fluids, in particular of a motor vehicle, with a sealing ring (26) is described. The sealing ring (26) serves to seal a pipe (16), in particular a central pipe of a filter housing (12), that penetrates through a flange-sided opening (18) of an end plate (20), in particular of an end element of a filter element (14). The sealing ring (26) features a central section (58) that connects it with the end plate (20). The sealing ring (26) features in its axial direction on both sides of the central section (58) elastic sealing sections (60, 62) which cause each a reduction of the inner diameter of the sealing ring (26) compared with the central section (58). The elastic sealing sections (60, 62) extend freely flexibly and can be bent away from the central section (58) such that they can be pressed—when the pipe (16) is mounted—by means of prevailing fluid pressures—when the filter system (10) is operated—in radial direction against the exterior wall of the pipe (16).

    摘要： A filter element has a first follower element with a first traction surface and a second follower element with a second traction surface provided for interacting with first and second mating surfaces of the filter housing, respectively. The first and second traction surfaces interact with the first and second mating surfaces to pull out the filter element from the filter housing. The first and second traction surfaces are spaced apart from each other along a longitudinal axis of the filter element and project radially into the interior of the filter element. At least one of the first and second follower elements has a stop surface adjoining circumferentially the respective traction surface. In a position of use, the stop surface interacts with a counter stop surface of the filter housing to form an at least unidirectional rotational degree of freedom blocking about the longitudinal axis relative to the filter housing.
