Instruction Extract: Understanding the Swash Plate Motor

The swash plate motor includes a cylinder block with nine pistons. The block’s end face contacts a valve plate with two ports (B and C) that alternate the pressure distribution. Here’s the principle of torque generation:

• When high-pressure oil enters port B, it applies force to the inclined surface, producing a reaction force and resultant torque transferred via the spline to the shaft.
• Introducing high-pressure oil to port C reverses the rotation.
• Formulae for output torque and revolution account for factors like pressure, flow, and mechanical efficiencies.
