An oil supply port is connected to an oil pressure pump that is selectively connected to either of one or another of cylinder ports connected to respective left and right chambers of a power cylinder. The valve body is provided with an intermediate partition plate extending into an oil pressure reaction chamber in the valve housing to divide the chamber into areas on opposite sides of the partition plate. The resultant pair of areas extend respectively on either side in the turning direction of the valve body, and the respective areas are connected to one or the other of the cylinder ports.</p> |
