Abstract

A fluid-displacing machine has a rotor member and a stator member relatively rotatable about a common axis. One of the members has an internal peripheral profile that is sinuous, opposed to which the other of the members has a peripheral profile that is circular. The contour of the sinuous profile generates an odd number of evenly spaced chambers interposed by cam surfaces and is developed so that the diametral distance between its opposite profile surfaces is constant. At least one diametrally disposed vane is slidably mounted in the circular member and adapted to continuously contact and sweep the sinuous profile surface of the other member, there being inlet and discharge passages leading into and out of each chamber respectively whereby upon relative rotation of the members pumping and/or compressing action is promoted.
