A fuel filter element has a screen fabric as a filter medium and a support tube supporting the screen fabric. A valve body guide for guiding a spherical valve body is provided. The valve body guide has a fluid channel and one or more support ribs for supporting the spherical valve body. The support ribs extend along a longitudinal direction of the fluid channel and project radially into the fluid channel. A filter assembly with such a fuel filter element is provided. The filter assembly has a ball valve with spherical valve body and a filter housing with a valve seat for the spherical valve body of the ball valve.

Fuel filter element and filter assembly

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.

Water drainage device, filter module, and method

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.

Filter element and filter assembly

A water drainage device for a filter module is provided with a valve housing that has a valve bore, a valve body received at least in sections in the valve bore, an actuation rod for actuating the valve body, and a coupling device operatively connecting the actuation rod with the valve body and enabling a tilting of the actuation rod in relation to the valve body. The water drainage device can be transferred from a closed state, in which the valve body seals in relation to the valve seat of the valve bore, into an open state, in which the valve body is lifted off the valve seat, and in reverse. The filter module has a filter housing with a housing top part. The valve body, upon transfer of the water drainage device from closed state into open state, moves toward the housing top part of the filter housing.

A valve unit has a plate-shaped valve body with a closure section and a connection section. The valve body has a cutout surrounded by a frame. The closure section has a closure tab that, beginning at a first fastening section at the frame, projects into the cutout. The connection section, beginning at a second fastening section at the frame, projects into the cutout and has a contact tab and a fastening point. The first and second fastening sections are arranged opposite each other at the frame along a longitudinal axis of the valve body. A filter head for the valve unit has a valve seat for a seal body of the closure section of the valve body. A fastening pin of the filter head fastens the connection section of the valve unit. A contact region of the filter head contacts a positioning region of the valve unit.

Valve unit, filter head for a valve unit, and filter system

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.

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.

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.

Valve device and fuel filter module

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.
