Abstract:
1. A pressure equalizing valve for a fuel tank or secondary fluid tank on a motor vehicle, comprising: at least one valve housing, at least one valve body movably arranged in the valve housing, at least one venting opening on a tank side, wherein the at least one valve housing, the at least one valve body and the at least one venting opening form a venting path openable or closeable by the valve body such that, when a predetermined transverse force is exceeded relative to a normal force which holds the valve body in a valve seat, the valve body is liftable or deflectable from the valve seat to open the venting path and, when falling below said transverse force, the valve body is automatically positionable in the valve seat to close the venting path, wherein the valve body is arranged so that excess pressure on the tank side acts hydraulically on the valve body, such that said valve body is pressed onto the valve seat, and wherein in the valve housing only one venting path is provided, which in a resting position and a horizontal position of the vehicle and/or of the tank in an installed position, is closed by the valve body.
