ABSTRACT:
A rotor is eccentrically journalled for rotation within a bore of a stationary housing formed with end walls and inlet and outlet ports. One or more blades are radially slidable within grooves in the rotor and biased into sealing engagement with the inner circumference of the housing. Rotation of the rotor and blades produces suction and pressure chambers within the housing to displace fluid from the inlet to the outlet. The rotor and blades are each formed in two sections with a resilient member inserted inbetween, the resilient members urging the respective sections longitudinally into sealing engagement with the end walls.
