The Operating Principles of a Variable Displacement Axial Piston Pump - Coursework Example

At a certain inclination (angle) of the swash plate as the pump’s shaft rotates a partial vacuum (suction) is created at the pump inlet that allows atmospheric pressure to push the fluid out of the oil tank (reservoir) into the pump intake. Simultaneously due to a certain angle of the swash plate a compression is created at the outlet that mechanically pushes the fluid out of the discharge line. The amount of fluid pumped per revolution of the pump’s input shaft can be varied and controlled by changing the angle of the swash plate which can further be controlled and adjusted through the swash plate adjusting valve as shown in Figure 1b.

If the swash plate is perfectly vertical to the drive shaft, there will not be any reciprocating motion of the pistons hence there will not be a flow of fluid, and vice versa (Huzij, Spano & Bennett, 2014). 2. Describe the valve operation. Answer. Irrespective of the types and applications of valves, all valves operate either by opening, closing, or partially obstructing various passageways of fluid.
