Abstract
A variable displacement wobble plate type refrigerant compressor includes a plurality of axially reciprocating pistons. A drive shaft rotates the wobble plate and thereby reciprocates the pistons within their respective compression chambers. Gaseous refrigerant is admitted to each compression chamber through a suction valve and discharged from each compression chamber through a discharge valve. Each discharge valve opens to a common discharge cavity. A hub is rotatable supported about a fixed axis within the discharged cavity, or downstream of the discharge cavity. A plurality of blades pivotally extend from the hub. A compression spring is disposed inside the hub for biasing the blades toward a flat condition. As discharged fluid moving through the discharge cavity impinges upon the blades, the blades are deflected to an angular, propeller-like, orientation for inducing rotation of the hub and thereby creating turbulence in the discharge fluid having a predominantly helical flow pattern downstream of the hub.
