Abstract: A filter housing has a housing pot accommodating a filter element. The filter housing has a connecting element connectable by a rotary and/or plug-in connection for connecting the filter with a connecting device. The filter housing has a securing ring forming a cup-shaped attachment section with a circumferential free rim. By rotary and/or plug-in movement, the attachment section is attached to an insertion section of the connecting device. The attachment section is provided with a sealing receptacle of a circumferential sealing device. The sealing receptacle is open in radial inward direction and has a radial sealing surface. The attachment section is connected at the free rim with the circumferential wall of the housing pot by crimping. The securing ring provides a first axial stop surface for an annular seal. A stop ring, inserted into the securing ring, provides a second axial stop surface for the annular seal.

Abstract: 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.

Abstract: 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.

Abstract: An air guiding arrangement for an internal combustion engine is provided with an intake manifold that supplies intake air to the internal combustion engine, wherein the intake manifold has a flow compressor apparatus with a compressor. A tank ventilation system for a fuel tank of the internal combustion engine is provided, wherein the tank ventilation system has an adsorption filter and a first ventilation line which is branching off the adsorption filter. A throttle device is provided upstream of the compressor in the intake manifold. The ventilation line is connected to the intake manifold and opens into the intake manifold at a location between the throttle device and the compressor.
