Abstract
A hydraulic press includes a press plate mounted for executing working strokes and return strokes; a hydraulic countersupport braking cylinder supported at an end zone of the working stroke for engaging the press plate at an end portion of the working stroke to cause deceleration of the press plate by the hydraulic countersupport braking cylinder; and a hydraulic shock absorber connected between the press plate and the hydraulic countersupport braking cylinder. The hydraulic shock absorber is arranged for compression from an expanded state by the press plate in an end zone of the working strokes. The hydraulic shock absorber has a shock absorber chamber containing hydraulic fluid; a throttle for setting a braking force in the shock absorber chamber to a magnitude smaller than the braking force of the hydraulic countersupport braking cylinder; and a resetting arrangement for returning the shock absorber into its expanded state.
