Abstract
A pressure compensating element ( ) for a control valve ( ) for controlling an overflow of a medium from a first pressure space ( ) into a second pressure space ( ) has a diaphragm ( ) separating the pressure space ( ) from one another. The pressure compensating element ( ) compensates forces acting on a valve body ( ) of the control valve ( ) and generated by pressure differences in the pressure spaces ( ). However, an overflow of a medium from one pressure space ( ) into the other pressure space ( ) takes place solely in the region of the control valve ( ).
