Direction for use
The cylinder block is mounted in fixed roller bearings in the housing. An even number of pistons are radially located in bores
inside the cylinder block. and the valve plate directs the incoming and outgoing oil to and from the working pistons. Each piston
is working against a cam roller.

  • Description of application effect

  • 使用效果描述

When the hydraulic pressure is acting on the pistons, the cam rollers are pushed against the slope on the cam ring that rigidly connected to the housing, thereby producing a torque. The cam rollers transfer the reaction force to the piston which are guided in the rotating cylinder block. Rotation therefore occurs, and the torque available is proportional to the pressure in the system. 
Detailed Images
Oil main lines are connected to ports A and C in the connection block and drain lines to ports D1, D2, D3 or D4 in the motor housing. 
The motor is connected to the shaft of the driven machine through the hollow shaft of the cylinder block. The torque is transmitted by using a mechanical shaft coupling or alternatively by splines.
