Valve arrangement for supply of pressure medium of two pressure chambers of hydraulic drive, has valve slides and readjusting surfaces of valve slides are subjected with pressure at pressure connection,

摘要

The valve arrangement has pressure connection (P), a return connection (R), power connections (B) and two valve slides (12,14) guided in a common valve drilling (16). The readjusting surfaces of the valve slides are subjected with pressure at the pressure connection, and the effective surface of the readjusting surfaces are implemented to control surface with surface variation.
