- Page 34 HYDRAULIC PUMP HYDRAULIC PUMP FUNCTION · The rotation and torque of the pump shaft are con- verted into hydraulic energy and the flow of pressu- rised oil is regulated in accordance with the demand from the various actuators. · It is possible to vary the pump delivery by changing the angle of the swash plate.
- Page 35 HYDRAULIC PUMP OPERATION Operation of the pump 1 - The cylinder block (4) rotates with the shaft (1) and the piston shoes (6) slide over the flat sur- face «A». The swash plate (3) moves over the cylindrical surface «B»; the angle « a » between the axis of the shaft (1) and the axis X of the swash plate (3) can be changed to alter the stroke of the pistons.

- Page 37 LOAD SENSING VALVE, PRESSURE CONTROL VALVE 3.1. OPERATING PRINCIPLE Controls the angle of the pump swash plate · The swash plate angle (and thus the pump delivery) is controlled in such a way that the pressure difference D PLS between the pump delivery pressure PP and the pressure PLS at the work port of the directional control valve is maintained at a constant value.
- Page 38 LOAD SENSING VALVE, PRESSURE CONTROL VALVE 3.2 LOAD SENSING (LS) VALVE FUNCTION · The LS valve controls the pump delivery according to the stroke of the directional control valve lever, i.e., according to the demand for oil flow from the actuators. ·...
- Page 39 0 bar (0 psi) as no fluid is delivered from the control valve outlets and the signal is connected to drain. At the same, the pump delivery pressure PP increases as there is no demand from the users. When the force exerted by the pressure PP in chamber b balances the force exerted by the spring (2), the spool (1) moves to the right and allows the fluid at pressure PP to flow into the chamber X of the piston (6) by connecting pas- sages c and d.
- Page 40 LOAD SENSING VALVE, PRESSURE CONTROL VALVE b. When a control valve lever is operated D0000470 · When a control valve lever is shifted from the NEUTRAL position, this generates an LS signal corresponding to the pressure PLS. · The LS signal pressure in chamber a moves the spool to the left, thereby connecting passages d and e. Chamber X is thus depressurised and the swash plate is moved to the maximum delivery position by the action of the spring (5).
