1). The oil is supplied to the "P" port and pases through the check valve CV1, CV2 and pilot operated check valve POV (option) to the high‐pressure side. At the same time, the "T" port is connected to the tank. Now the entire flow of the pump will pass straight through the intensifier, and a cylinder on the high‐pressure side "H" will move rapidly forwards.
In hydraulic systems, it is often necessary to use varying operating pressures. A system which works perfectly with a high rate of efficiency can be achieved only if it is possible to adjust the pressure precisely to the load in question.
Using pressure intensifiers, designers have greater flexibility with regard to choice of operating pressure. The hydraulic load becomes more uniform throughout the machine's cycle. The pressure intensifier starts to work only when there is a need for a high pressure.The rest of the time it is passive, has no internal consumption and thus does not influence the performance of the system.
