Hydraulic or pneumatic motor - has double-acting ram coupled by pin to parallel endless chains running around sprockets

摘要

The pneumatic or hydraulic motor has a tangential action comprising a double acting piston with rod working in a cylinder to form a ram. the reciprocating action of the ram can be transformed into rotary movement by means of a pin couping its rod to two parallel endless chains. The drive from the sprocket sets is taken to a common shaft so as to synchronise chain movement.
