Abstract
A compact fluid actuated working cylinder is disclosed having a cam driven by a piston via a flexible tension member. At the ends of the cylinder housing there are deflection pulleys for providing continuous tension for the tension member. The pulleys are each mounted on pulley supports which extend from secondary bores in the main cylinder housing. The pulley supports are spring loaded and urge the two pulleys away from the cylinder housing and each other. The pulley supports are preferably rectangular in cross-section to protect against torsion.
