Abstract
In a hydraulic circuit for controlling a clutch/brake system having a clutch that is disposed separately from the brake in a main drive of a mechanical press, wherein the brake is spring-loaded in a direction opposite to an engagement direction of the clutch, a piston/cylinder unit is provided that moves the clutch and the brake into a coupling position or a braking position, respectively. A pressure line connects a press safety valve to the piston/cylinder unit for generating torque at the clutch. A bidirectionally passable hydraulic connection connects a metering piston unit to the piston/cylinder unit in parallel to the press safety valve.

A hydraulic circuit for controlling a clutch/brake system comprising a clutch and a brake, wherein the clutch is disposed separately from the brake in a main drive of a mechanical press, wherein the brake is spring-loaded in a direction opposite to an engagement direction of the clutch;
- the hydraulic circuit comprising:
- a piston/cylinder unit adapted to move the clutch and the brake into a coupling position of the clutch and a braking position of the brake, respectively;
- a press safety valve;
- a pressure line connecting the press safety valve to the piston/cylinder unit for generating torque at the clutch;
- a metering piston unit;
- a bidirectionally passable hydraulic connection connecting the metering piston unit to the piston/cylinder unit in parallel to the press safety valve.
