ABSTRACT:
An apparatus for controlling the flow of a pressure fluid in a motor includes an arm which cooperates with a locking device to regulate the flow of the pressure fluid through a shut-off member or valve. The arm is connected to a lever which is pivotable about the same axis as the arm. Through resilient means, the arm and the lever are prestressed so that upon movement of the lever into a predetermined position, the arm which is locked in its end positions by a respective lock pawl is released and impelled from one end position into the other. During the movement of the arm, the shut-off valve is actuated so as to regulate the pressure fluid.
