As shown in Fig. 4, the effective working area of the rod-less chamber of the hydraulic cylinder A;=50cm², the working load of the cylinder F = 5000N , the setting pressure of the pressure reducing valve is 2MPA, and the setting pressures of the valve a, b and c is 5MPA, 1.5 MPa and 3MP respectively. Questions: 1) How much are the pressures at the outlet of pump and in the rod-less chamber of hydraulic cylinder respectively when piston of the cylinder is moving forwards at the working speed. Please give the reason. 2) How much are the pressures at the outlet of pump and in the rod-less chamber of hydraulic cylinder respectively when piston of the cylinder reaches and stops at the end. Please give the reason.
