Doosan DX35Z Manual Instruction Extract:

Swash Plate Motor

The cylinder block incorporates nine pistons. The end face of the cylinder block is in contact with the valve plate having two woodruff ports B and C (distributing valve to change over between high and low pressures).

Principle of generating torque
When high pressure oil (Pressure P) is introduced to the B port, the inclined surface is pushed by a force of “F = P x A, A: piston sectional area” per piston and the piston receives a reaction force from the inclined surface.

The piston that is restricted in the moving direction by the cylinder block due to the reaction force generates a rotating force. The total of rotating force by the reaction force of the high pressure side pistons works on the cylinder block. The generated rotating force is transmitted as a torque to the shaft via the spline to turn the shaft.
On the other hand, if the high pressure oil is introduced to the C port, the opposite rotation is caused.
The output torque and the revolution are calculated as follows:


D: Displacement (cm3/rev)
P: Effective drive pressure (MPa)
Q: Inflow (L/min)
ηm: Mechanical efficiency (motor) (%X10-2)
ηv: Volumetric efficiency (motor) (%X10-2)
i: Speed ratio of reduction gear
ηG: Efficiency of reduction gear (%X10-2)
