ABSTRACT:
A reciprocating pneumatic motor for hydraulics has a pair of guide grooves on the inner wall of a cylinder provided, together with a pneumatic piston and a shuttle valve to function pneumatically. The piston has a seal ring which passes the guide grooves to allow air to flow into the shuttle compression chamber, pushing the shuttle valve and opening up a channel for the venting of air. This continuous air flow and venting causes the piston to reciprocate. In addition, the piston is integrated with a ring plate using plastic ultrasound technology which simplifies the structure of the pneumatic motor.
