Detailed view: 1 Press Ram. 2 Cylinder rod. 3 Cylinders with controlled return. 4 Retention valves. They intercept the flow of the hydraulic fluid into and out of the cylinders. Their presence enables to reduce the springback effect to a minimum. 5 Distribution unit with pressure-reducing valve. 6 Adjustable pressure-reducing valve. It regulates the outflow of hydraulic fluid during the cylinder compression phase. This pressure reducing valve ensures that the pressure, i. e. the cylinder contrasting force, remains constant. 7 Air-oil exchanger. It switches on automatically and ensures that the fluid temperature remains constant. 8 Compensatory flow regulator, to guarantee constant speed during the return phase. 9 Two-position, two-way electrical distributor. When its coil is off, it shunts the hydraulic fluid into the air-oil exchanger; when its coil is on, it shunts the hydraulic fluid into the return circuit of the cylinders. 10 Electromagnetic safety sensor: checks the correct position of the sliding tool part, which is jam-prone at the end of cycles. 11 Flexible hose-pipes with quick coupling connectors to distribution unit. 12 Wheeled command unit.
