Abstract
The mechanical press, particularly a toggle press, comprises a hydraulic member connected between the force transmitting and force receiving components, such as a toggle joint, carriage, anvil, and platen. The anvil is mounted on a hydraulic member which is located in a hydraulic chamber. The hydraulic member acts as a press cushion which is continuously connected with a large volume fluid reservoir which is maintained constantly under a gas pressure. The hydraulic member has a maximum filling volume which is at most 1% of the volume of the fluid reservoir.
