The sensor (20) having at least one pair of electric lines (38) for an electric circuit with at least one electric contact (36) each. The electric contacts (36) of at least one pair of electric lines (38) are arranged such that they are contactless at least in one noncontact state of the filling-level meter. The electric contacts (36) can be connected in at least one contact state by use of at least one mechanically operated electric connecting element of the filling-level meter. The electric connecting element does not necessary has to be part of the sensor (20). The at least one electric connecting element can be mechanically connected to a float assembly. The at least one electric connecting element in particular with the float assembly can be moved relative to the at least one pair of electric contacts (36) between the at least one noncontact state and the at least one contact state. The sensor (20) comprises at least one electric bypass resistance (42), which electrically connects the at least one pair of electric lines (38).


The invention relates to a coupling arrangement (10) having a first coupling body (20), a second coupling body (40) and a coupling bracket (30).

The coupling bodies (20, 40) provide a mutual second geometrical position (102) for locking the catching means (60, 80) in order to establish the connection between the coupling bodies (20, 40). The coupling bracket (30) is configured to cover at least a part of one of the coupling bodies (40) inserted into the other of the coupling bodies (20). At least the receiving one of the coupling bodies (20) provides catching means (64) for establishing a connection to the coupling bracket (30). The coupling bracket (30) provides corresponding catching means (72) for establishing a connection between the coupling bracket (30) and at least the receiving one of the coupling bodies (20).

The invention relates to a fluid duct (10), particularly an inlet air duct for a combustion engine in a vehicle, having a shell (12) enclosing an inner volume (30) and comprising at least one upper surface (14) and at least one side wall (16, 17), which upper surface (14) represents an upper surface (14) of the fluid duct (10) in its mounted state in an intended position. The side wall (16, 17) is configured to be selectively collapsible upon action of a force (34) applied to the upper surface (14) so that in a collapsed state of the shell (12) the upper surface (14) and the at least one collapsible side wall (16, 17) collapse below a predefined level thus reducing a height (28) of the shell (12).


The present invention relates to a gas-ducting system (12), in particular an air-ducting system (12), in particular of an air intake system, in particular of an internal combustion engine, in particular of a motor vehicle. The gas-ducting system (12) comprises an acoustic system (14). The acoustic system (14) has an adapter (20). The adapter (20) comprises a connection pipe section (24) for connecting the adapter (20) to a gas guiding duct (10), in particular a main air guiding duct. Further, the adapter (20) comprises at least two branch pipe sections (26). The branch pipe sections (26) are connected with one end each to the connection pipe section (24). The other end of the branch pipe sections (26) each have at least one part (30) of a fastening means (28) for connecting at least one acoustic device (16, 18).

Disclosed is a filter system having a filter element (10), a filter housing and a sealing device (20) sealing off a housing interior space (120) from a surrounding environment (122). The sealing device (20) has a seal (24) arranged on a seal carrier (22). Also disclosed is a sealing device (20) for the installation in such a filter system (100) and an arrangement comprising a filter element (10) and a sealing device (20).


Patent

An air filter has a filter housing and a filter element inserted in the interior of the filter housing. The filter element has an inflow surface and an outflow surface and a filter medium that extends between inflow and outflow surfaces. The filter element has a circumferentially extending seal arranged in the area of the inflow surface or outflow surface and interacting in the mounting position with the sealing surface of the filter housing to separate inlet and outlet of the air filter. A support device clamps the filter element transversely to the insertion direction in the filter housing by a transverse clamping action in a support area that is spaced from the seal. The transverse clamping action results by an insertion movement of the filter element into the filter housing by interaction of the filter element with inner sides of the filter housing.
