This example model shows how a hydraulic system can work with filters. The oil is filtered in two places, from the tank to the pump and from the pump to the control valve. At time t = 1, the control valve opens up for flow from the pump, and the body will be pushed upwards At time t = 2, the control valve closes again, and the body will stop moving.

Fig. 1 shows how the pressure and mass flow in the filter changes. Fig. 2 shows how the system moves a load. Fig. 3 shows the pressure in the double cylinder.
