<p>The cam controls the position and movement of the piston rotors and hence the relationship of the piston pairs with respect to each other. It comprises a driven member rigidly connected to a rotatable drive shaft and at least two driving members each rotatively and rigidly connected by the offset drive member to each piston rotor. Two driving members are positioned in adjacent quadrants about the driven member. The driven member comprises two diametrically opposed pins, two diametrically opposed locking cams and two diametrically opposed relief sections.</p> |
