A whole blood filtration device is provided with a filter membrane separating a feeding volume and a clean side of the filter membrane from each other. The feeding volume communicates with a first feeding side opening and with a second feeding side opening. The filter membrane has pores with a pore size that ensures permeability of the filter membrane to blood plasma/serum and that retains blood cells. The first feeding side opening can be coupled to a first blood pump for feeding blood from the first feeding side opening into the feeding volume so that blood plasma/serum permeates the filter membrane and blood cells, retained by the filter membrane, exit from the feeding volume through the second feeding side opening.

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 filter module for a filter assembly has a primary filter element and a secondary filter element. A water separation interface is provided for discharging water, which has been separated by the primary filter element from a fluid to be filtered, from the primary filter element. A primary filter interface is provided for discharging fluid, which has been filtered by the primary filter element, from the primary filter element. A secondary filter interface is provided for discharging the fluid, which has been filtered by the secondary filter element, from the secondary filter element. The water separation interface, the primary filter interface, and the secondary filter interface are arranged coaxially to a symmetry axis of the filter module. The water separation interface, the primary filter interface, and the secondary filter interface are each designed for outflow of material flows in axial direction of the symmetry axis.

A housing module of a fluid treatment module of a fluid system is provided with a fluid housing with inlet and outlet for fluid. The fluid housing has a housing part with a receiving chamber for a fluid treatment component for treatment of fluid and an installation opening, closable by a housing closure part, for installation of the fluid treatment component in the receiving chamber. A housing connecting section is provided for connecting the housing part and the housing closure part to each other. The housing module has an externally positioned support structure that surrounds the housing part like a sleeve and has a reinforcement region that extends about the housing connecting section. The support structure has a fastening region for attachment of the housing module on a holding component of the fluid system. The connection of the housing part with the housing closure part is a direct connection.

A recirculation module for a fuel prefilter unit of a combustion engine has a temperature-controlled actuating element that transfers the recirculation module, based on a filter raw side feed temperature of the fuel, from a cold start state into a normal operating state and back. In cold start state, an engine return line from the combustion engine to the recirculation module is in fluid communication with a filter element raw side of the fuel prefilter unit and the engine return line is separated in regard to fluid communication from a tank return line of the combustion engine. In normal operating state, the engine return line is separated in regard to fluid communication from the filter element raw side and is in fluid communication with the tank return line. A check valve prevents return flow of fuel from the tank return line into the engine return line.

A discharge control device for a filter system and a filter system for filtering a media flow of a first and a second medium is provided with a collecting chamber that collects the second medium separated from the media flow. A sensor arrangement with a first sensor unit, a second sensor unit, a first shut-off valve having a closure body, and a second shut-off valve is provided. The first sensor unit is operatively connected to the first shut-off valve. The first sensor unit has a float that purely mechanically actuates the closure body of the first shut-off valve. The second shut-off valve is arranged in series in flow communication with the first shut-off valve. The second shut-off valve has an electromagnetically actuatable valve controlled by the second sensor unit as a function of a fill level of second medium in the collecting chamber.

A control valve for adjusting fluid flow has a cylindrical housing bushing with a first and a second flow opening. A control bushing is arranged coaxially in the housing bushing and adjustable between control positions opening and/or closing the flow openings. A first spacer disk and a second spacer disk are arranged axially spaced apart at the housing bushing and surround the housing bushing. At least the first spacer disk is arranged eccentrically at the housing bushing by eccentric displacement relative to a longitudinal axis of the control valve. A first side of the housing bushing has a larger radial spacing relative to an outer rim of the first spacer disk than a second side of the housing bushing. At least one of the first and second flow openings is arranged at the first side of the housing bushing. A cooling system is provided with such a control valve.

A blood filtering device has a filtration section with filter medium separating raw side and clean side. A first communication path connects raw side and a first variable blood reservoir volume; a second communication path connects raw side and a second variable blood reservoir volume coupled to a receptacle. When varying the first variable blood reservoir volume, blood contained therein flows through first communication path to raw side, plasma/serum passes through the filter medium from raw side to clean side, and residual blood flows from raw side through second communication path into the second variable blood reservoir volume. When varying the second variable blood reservoir volume, blood contained therein flows through second communication path to raw side, plasma/serum passes through the filter medium from raw side to clean side, and residual blood flows from raw side through first communication path into first variable blood reservoir volume.

A fluid housing of a fluid treatment system of a fluid system has a housing part of plastic material that is provided with a receiving chamber for accommodating a fluid treatment component; an installation opening, closable by a closure housing part, for installing the fluid treatment component in the receiving chamber; and a housing connecting section to connect the housing part to the closure housing part. A housing fastening section is provided with which the fluid housing can be fastened to a holding component of the fluid system. An insert is at least partially introduced into the plastic material of the housing part. The insert is provided with a reinforcement region extending with sections thereof in the housing connecting section and is further provided with fastening region extending with sections thereof in the housing fastening section. A fluid treatment system with such a fluid housing is provided.

An exhaust gas turbocharger for an internal combustion engine has a compressor arranged in an intake tract of an internal combustion engine for precompression of air passing through the intake tract to the compressor. A switchable air guiding device is arranged upstream of the compressor, wherein the switchable air guiding device supplies an air flow to the compressor in at least two different ways. The air guiding device has at least two components, wherein the at least two components are substantially made from plastic material.
