Abstract: 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.

Abstract: A filter for filtering fluid has a filter housing with fluid inlet for fluid to be filtered and fluid outlet for filtered fluid. A filter element arranged in the filter housing separates fluid inlet fluidically from fluid outlet. A bypass valve arrangement is arranged fluidically between fluid inlet and fluid outlet such that it fluidically connects in an open state fluid inlet to fluid outlet. The bypass valve arrangement has a valve closure body arranged movably in the valve housing between a closed position and an open position. The bypass valve arrangement has a valve seat element with valve seat. The valve closure body rests sealingly at the valve seat in closed position. The valve seat element is connected to a part of the valve housing by a mechanical connection realized by relative rotation between valve seat element and part of the valve housing about a valve axis.

Abstract: 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.

Abstract: 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.

Abstract: A filter system (200) includes a housing (210) in which a replaceable filter element (100) is arranged between a pre-filtration side (202) and a post-filtration side (204). The filter element (100) has an element-fixed central tube (150), wherein a closure element (10) is provided on a housing side, the closure element (10) opening a post-filtration-side fluid outlet (250) when the filter element (100) has been inserted, and blocking the post-filtration-side fluid outlet (250) when the filter element (100) has been removed. The filter element (100) has an actuating element (160) for the closure element (10).

Abstract: A water separator for water contained in fuel has a water separator housing with a separator element. A water collecting chamber is arranged in operation of the water separator below the separator element. A water collecting chamber through opening fluidically connects the water collecting chamber with the separator element. A drainage through opening has a first end which leads, for draining water from the water separator, out of the water separator.
