Spherical piston hydraulic motor

for construction equipment

Hydraulic circuits and installations can be simplified, and costs reduced, using this bent axis innovative motor able to operate without a drain connection. The back piece of the motor is designed to allow the drain flow to go to the low pressure line, thus ensuring that the pressure in the housing is equal to the minimum pressure in the circuit. For bi-directional rotation, a spring-loaded accumulator is incorporated, which takes out the pressure peaks which occur with rapid change in direction. Characteristics and advantages : no drain line, only inlet and outlet lines are needed, the motor is drained via the return line. Applications : construction equipment, agricultural machinery, excavator attachments.
