ABSTRACT:
A pneumatic type of reciprocating movement device capable of a high cycle speed over a short stroke. A rod member with a flange is slidably mounted in a cylinder member such that the flange divides a cavity in the cylinder into a left and right portion. Intake and exhaust passages are moved in and out of communication with the cavity sides by the moving interface of the rod and cylinder, such that an alternating force is exerted on the flange sides causing the flange and rod member to move in a reciprocating motion without the use of an auxiliary system of valve switching.
