How is the angle of a swash plate controlled?
How is the angle of a swash plate controlled?
In variable-displacement models, the swash plate is installed in a movable yoke ( Figure 3-17 ). By pivoting the yoke on pintles, the swash plate angle and piston stroke can be increased or decreased. Figure 3-17 shows a compensator control, but the angle can also be controlled manually or by a variety of other means.
How is stroke length controlled by swash plate?
Swash plate causes pistons to reciprocate. In these pumps the size and number of pistons as well as their stroke length also determine the displacement. The stroke length is controlled by the swash plate angle. In variable-displacement models, the swash plate is installed in a movable yoke (Figure 3-17).
Can a swash plate be connected to multiple pistons?
You can connect multiple swash plate blocks to multiple pistons. The plate is in dynamic equilibrium if the net work by the piston, actuator, and plate is zero: FPδP is the work done due to piston displacement. FAδA is the work done due to actuator displacement.
What should be the offset of the swash plate?
The radius of the pitch circle where the pistons are located, that is, the cylinder block pitch radius. The parameter must be greater than zero. The default value is 0.05 m. The offset between the piston tip and the swash plate.

How is the swash plate connected to the cylinder block?
A ball-and-socket joint connects the end of each piston to a slipper pad, which is kept always in contact with the swash plate. During cylinder block rotation, each piston periodically passes over the discharge and intake ports on the valve plate.
What causes the swashplate to return to the center?
After a certain offset, the ability of automatic centering of piston components will make the swashplate return to the center. These two effects will eventually lead to back and forth oscillatory movement of the swashplate, and the vibration in radial direction can become abnormal.
