HYDRAULIC PUMP
OPERATION
Piston Pump
This pump is a variable displacement piston pump with a single cylinder block, which discharges two equal volumes.
Ten pistons (2) are installed in the cylinder block (1), and the end surface is in contact with the valve plate (3). The suction port C and the discharge port A of the pump P1 and the discharge port B of the pump P2 are arranged in the valve plate (3). On the other hand, the swash plate (4) is fastened to the housing at a given inclination, and the pistons (2) rotate along this swash plate (4).
When the shaft (5) is rotated, the cylinder block (1) rotates, the pistons (2) in the cylinder block execute reciprocating movement along the swash plate (4), and the pump executes suction and discharge. At this time, the pistons in contact with the discharge port A of the valve plate (3) operate as the pump P1, while the pistons in contact with the discharge port B operate as the pump P2.
In this way, the ten pistons (2) execute one suction and discharge stroke with each revolution of the cylinder block (1), so that suction and discharge are executed continuously when the shaft (5) is rotated continuously.
As the piston stroke displacement depends on the inclination of the swash plate (4), the discharge flow quantity can be changed by changing the inclination of the awash plate (4).
