Abstract
Hydraulic or pneumatic auxiliary valve adapted to be interconnected in a hydraulic system including a hydraulic pump (3), a reverse pressure valve (4) and two or more preferably intermittently operating cylinders (1, 2) or motors, in which the auxiliary valve is directly interconnected in the conduit for at least one (2) of the two cylinders, and in which the auxiliary valve comprises a valve body (18) having inlet (12) and outlet (13) and between said parts a movably mounted control valve (20), and a servo cylinder which is cooperating with the control valve and which is reciprocatably mounted in the auxiliary valve body (18) and which is actuated by pressure in a branch conduit from the inlet (12) of the auxiliary valve. The control valve (20) and the servo cylinder (23) are formed with cooperating means (27, 28) for providing a temporary closing or choking of the connected cylinder or cylinder group so that said cylinder or cylinder group is actuated with full force only once per multiple of operation cycles, whereas the other cylinder or cylinders are actuated with full force for each operation cycle of the servo valve (23).
