ABSTRACT:
The invention can be used for reversible pulsationless rotor high-pressure machines which can operate in pump and in motor mode. The inventive machine comprises a working chamber and an additional working chamber, separating jumpers and regulating elements. Said regulating elements are connected to each other with the aid of a kinematic link in such a way that the motion of one regulating element initiates the motion of another regulating element. Working cavity of said working chambers are arranged in an axial direction oppositely to each other and connected to each other by means of channels. A mechanism setting an axial relative position of displacers is embodied in such a way that it always provides a sliding contact of at least one displacer with each regulating element. Said invention makes it possible to extent the functional capabilities of similar rotor machines and improve the operational parameters thereof.
