(C) Alternative

And Why?

The pressure plate is used in the manufacture of the motor of:
(A) Gear
(B) Palettes
(C) Pistons

And Why?

Thank you for your time, have a nice day :)

Answer 1

1) Gear motors are hydraulically balanced so as to not to have buckling forces on the driving shaft. Because without the hydraulic force on the gear the pressure is distributed in two sides it tends to not to drive the driving shaft. Here the hydraulic force applied on only the driving shaft to work and avoid unneccesary buckling loads on the other shafts.

2) In axial motors pressure compensators used since it suppose to store the pressure at the end of the suction for attaining the uniform pressure in motor

3) Pressure plate is used in the manufacture of palettes. Since the palette used to stop and relief the pressure.
