BOSCH REXROTH press cylinder with an integrated rapid traverse piston

It is a press cylinder with an integrated rapid traverse piston.
The large hole at the bottom is used to fill the piston chamber when it is extended quickly. Here the cylinder connection is connected directly to the tank via a suction valve. In the working position, the press pressure is then built up via the G 1/2" base connection and the suction valve closes automatically. It is recommended to replace the seal before use (Hunger-Service).
