Abstract (en)
[origin: EP1270103A2] The working machine has a working cylinder (4) to move a tool (2) in which the rod-side working cavity (6) has a cross section much smaller than that of the piston-side cavity (1). Rod-side outflow can be blocked by a regulating valve (8). There is also an emergency valve (12) to connect the rod-side cavity to a separate hydraulic supply (13, 15)in the event of an emergency stop.
