The valve for pressure compensation and/or for emergency venting of a container, preferably of a housing of a vehicle battery, has a housing (6) with an inlet (6a) that is closable by at least one valve element (23) subjected to a closing force in a first position. The housing (6) is at least partially gas-permeable and preferably water-tight, and has at least one outlet (26) which is located behind the valve element (23) when the valve element (23) assumes its first position. So that in case of a malfunction even larger quantities of gas can be guided to the exterior through the valve, is the valve element for an increased pressure surpassing the closing force at the inlet (6a) is adjustable in the direction toward a second position against the closing force, in which the valve element (23) at least partially opens the outlet (26) such that the outlet (26) is directly connected in flow communication with the inlet (6a).

A fluid control device has a body, actuator, and slam-shut device. The body defines an inlet, an outlet, and a plurality of slam-shut openings, and a seat is positioned along a flow path between the inlet and outlet. The actuator is configured to modulate a position of a first control element relative to a first side of the seat along an actuation axis to control a fluid pressure. The slam-shut device has a second control element that is movable along the actuation axis and is biased toward a second side of the seat and a slam-shut actuator configured to trigger the second control element to move to the closed position in which the second control element contacts the second side of the seat. The slam-shut actuator includes a shaft and the slam-shut actuator and shaft are positionable in any one of the plurality of slam-shut openings in different configurations.

A ventilation valve for a vehicle for letting air out of a vehicle interior includes a valve frame with at least one through opening, and at least one valve flap which is mounted on the valve frame and is adjustable between a closed position and an open position. The at least one valve flap closes the at least one through opening in the closed position and opens up the at least one through opening in the open position. Air escaping through the at least one through opening flows from an air inlet side to an air outlet side along a main flow direction. A wall bounding the at least one through opening is inclined into the air flow in such a manner that the through opening tapers in the main flow direction.

A valve includes a deformable portion connected to a rigid portion. A portion of a surface of a frustoconical body of the rigid portion is disposed adjacent a portion of a surface of a frustoconical body of the deformable portion. A portion of a surface of an upper axially-extending portion of the rigid portion is disposed adjacent a portion of a surface of an upper axially-extending portion of the deformable portion. A portion of the surface of the frustoconical body of the deformable portion that is not disposed adjacent a portion of the surface of the frustoconical body of the rigid portion defines a circumferential void. The circumferential void is in fluid communication with a plurality of upstream radial bypass passages extending through the frustoconical body of the rigid portion.
