Abstract

The invention makes it possible to increase the reliability of a rotary vane machine. An oval rotor 4 is eccentrically mounted in housing 1 with inlet and exhaust ports 2, 3. Spring-loaded blades 7 are placed in groove 5 of rotor 4. Groove 8 is made in housing 1, in which it is possible to interact with outer surface of rotor 4 spring separating plate 9. It is displaced in the direction of the window 2 relative to the vertical diametrical axis of the housing 1 by an amount equal to half the thickness of the plate 9. The groove 5 is made rotated relative to the major axis of the oval in the opposite direction rotor 4, which provides a smoother interaction of the plate 9 and the groove 5. 1 Il.

Rotary machine works as follows.

When the rotor 4 rotates, the working medium enters the inlet port 2 and, due to an initial volume change,

chambers 6 are pushed into outlet port 3. Plate 9 reciprocates and ensures reliable separation of the inlet and outlet ports. The displacement of the plate 9 toward the inlet port 2, as well as the groove 5 in the rotor 4, ensures their smoother interaction during the operation of the machine.
