ABSTRACT:
A pressure compensation valve arrangement for opening automatically with the occurrence of a pressure difference on opposite sides of a dividing wall including a valve stem having a valve head at one end biassed into sealing relationship against an annular valve seat by a compression valve spring acting at the side of the dividing wall remote from the head and at a flange at the other end of the valve stem. The valve stem at its other end has a hollow cavity and has laterally recessed openings between vertically shaped connecting ribs. The cavity and openings communicate with a passageway bounded by the valve seat when the pressure on the valve stem exceeds a predetermined safety value.
