A Hastie-built variable delivery pump of the Hele-Shaw rotary plunger type supplied as a component of the firm's electro-hydraulic steering gear. This type of pump enables the direction of movement of the hydraulic fluid in the steering system to be reversed without reversing the rotational direction of the pump.

Jun 20, 2018 · The Hele-Shaw pump is not a very easy pump to explain, unless you can get hold of a decent animation. There are a few on YT, but they aren’t very good. Armed with one of these anyway, the way the pump works is by moving the pumping pistons out of centricity with the central block.

The pumps may be Hele-Shaw radial piston type or a development of the axial piston V.S.G. pump. The strokes of the pump pistons in both types of pump can be varied and the flow of oil to and from the pump can be reversed. When the operating rod of the pump is in mid position, there is no flow of oil. Variable delivery pumps

(b) Variable Delivery Pump. A Variable Delivery Pump are those pumps whose discharge varies according to the need. It is used where continuous change in fluid flow is required. The principle behind variable displacement pump is to change the pump stroke in order to vary the amount of fluid displaced according to the requirement.

May 09, 2019 · A hydraulic pump has one mission, and that is to transform incoming mechanical energy at its shaft into hydraulic energy capable of transferring force to actuators somewhere downstream. This transfer of force is common to both fixed and variable pumps, but the method delivery is quite different.

The rotor set is comprised of the rotor, eleven wings guided radially in the rotor, the cam ring and the outer ring. The cam ring of this energy-saving variable displacement pump is eccentrically mounted and hydraulically adjustable. Until a permanently set breakaway point is reached, the Varioserv® behaves like a conventional power steering pump.
