Title: Double acting piston operating system - has piston movable in cylinder which forms ring piston in outer chamber, with selective fluid supply to two chambers
Inventor: MILLER EMIL
IPC: F15B15/16
Filed: 1976-12-23
Abstract: The fluid pressure driven system has a piston, axially movable in a cylinder, which in turn is formed as a ring piston, and is axially movable in an external cylinder. The ring chamber formed between the cylinder walls is connected at one end, via a first pressure medium conduit to a control valve. The piston rod-sided chamber of the internal cylinder is connected to the same valve via another pressure medium conduit. The opposite ring chamber end is connected to a medium conduit which simultaneously charges both pistons and leads to a changeover valve. The control valve has two switch positions. In one position, the first conduit is sealed, and the others are open, so that with low load on the arrangement, the ring piston is retained in the external cylinder, and the internal piston acts on its own. In the second position, the first conduit is open and the others are sealed, so that both pistons move simultaneously as a single unit.
