Abstract

The hydraulically operated spring brake and clutch has an annular cylinder hydraulically opened and closed by springs acting via tension screws passing through the cylinder, being particularly for eccentric presses. The springs (2) are in the form of self-sealing spring components, sealing the pressure chamber off from the outside and typically comprising plate springs (3). The screws (6) can fixed in the cylinder (9), passing through the piston (1) and piston chamber (10).
