Figure 4-11 illustrates the operation of the radial piston pump. The pump consists of a pintle, which remains stationary and acts as a valve; a…

Many hydraulic applications are similar to Figure 2.16, where a workpiece is held in place by a hydraulic ram. There are essentially two distinct requirements…
In axial piston pumps of the in-line type, where the cylinders and the drive shaft are parallel (fig. 4-13), the reciprocating motion is created by…
referred to as limited rotation cylinders, of the single or multiple, bidirectional piston are used for turning, positioning, steering, opening and closing, swinging, or any…
Another type of axial piston pump, sometimes referred to as an in-line pump, is commonly referred to as a Stratopower pump. This pump is available…
There are two types of manually operated reciprocating pumpsโthe single-action and the double-action. The single- action pump provides flow during every other stroke, while the…
The term reciprocating is defined as back-and forth motion. In the reciprocating pump it is this back-and-forth motion of pistons inside of cylinders that provides…
Screw pumps for power transmission systems are generally used only on submarines. Although low in efficiency and expensive, the screw pump is suitable for high…
The lobe operation as pump uses the same principle of the external gear pump described previously. The lobes are considerably larger than gear teeth, but…
Another design of internal gear pump is illustrated in figures 4-5 and 4-6. This pump consists of a pair of gear-shaped elements, one within the…
