Master cylinder for the speed of access restrictions and security through the trip exchanging to control switches.

The hydraulic system of injection molding machine is the representative example, it need to controlcylinderspeed and hold pressure, so it indeed to use pressure and flow rate multiple valve.
In this paper, the principle of variable speed pump control hydraulic differential cylinder is designed, and the simulation model of system is built, and the simulation research is carried out.
