摘要

A piston is slidably accommodated in a cylinder and subdivides the interior thereof into a first and a second chamber located at opposite axial sides of the piston. A supply conduit communicates with the first cylinder chamber. A source of pressurized fluid includes a pressure conduit and a fluid reservoir includes a return conduit. A control unit is connected with all of these conduits and includes a control member slidable between a neutral position in which it disconnects the supply conduit from the pressure conduit and from the return flow conduit, a first operating position in which it connects the supply conduit with the pressure conduit while disconnecting it from the return flow conduit, and a second operating position in which it connects the supply conduit with both the pressure conduit and the return flow conduit. A throttling passage connects the cylinder chambers with one another.
