Abstract

The invention relates to the field of compressor engineering and allows increasing the service life of the compressor. For this, the separator plate 10 is fixed in the housing 1. In the flexible strips 11, of which the plate 10 is made, holes are made. Transitions from the walls of the groove 6 in the housing 1 to the inner surface of the latter are made in the form of a curved surface. The transition from the surface of the rotor 5 to the groove 7 from the side of the discharge pipe 2 is made in the form of a collar. 1 hp f-ly, 6 ill.

The invention relates to compressor building.

The purpose of the invention is to increase the work resource.

1 shows a compressor, a section; FIG. 2 - mounting plate in the housing; FIG. 3 shows two smooth transitions from the groove in the housing to the internal surface of the housing in FIG. 4 — the same with the collar on the rotor; FIG. 3 shows a separator plate consisting of separate strips; in FIG. 6 — flexible strips with possible shape of through holes

A rotary compressor with a roll-out; with a rotor includes a housing 1 with a pressure 2 and suction 3 nozzles, eccentrically mounted in housing 1 on shaft 4 of rotor 5, and in housing 1 and rotor 5 radial grooves 6 and 7 are made in which ; The possibility of reciprocating movement and with the formation of working chambers 8 and 9 is provided with a separator plate 10 made of at least two flexible strips 11 installed to form a gap 12 between them. Separating} plate 10 is rigidly fixed in the groove | 6 of housing 1. The gaps 12 of plate 10 receive lubrication from channel 13. Through {flexible strips 11, except for two edges; they have through holes 14 which can be of different shapes. JI epokhody from the walls of the groove 6 in the housing, 1 to the inner surface of the housing 1 is made in the form of a smooth curved surface. The transition from the surface of the rotor 5 to the groove 7 from the side of the injection pipe 2 is made in the form of a flange 15, the surface of which, facing the body 1, has a curvature corresponding to the curvature of the transition surface from the inner surface of the body 1 to the groove 6 from the side of the discharge pipe 2.

The compressor works the following way.

When the compressor shaft 4 rotates, the gas enters through the suction nozzle 3, is compressed and supplied to the discharge nozzle 2. At the end of the operating cycle, thanks to the shoulder, all gas from the working chamber is drawn by the rotor 5 to the discharge nozzle 2.

Claims (2)

1. Rotational compressor with a rotary rotor, comprising a housing with a discharge and suction nozzles, an eccentric rotor mounted in the housing, and in the latter and the housing there are radial grooves in which a separating plate is placed with the formation of working chambers made of at least two flexible strips installed with a gap between them, characterized in , in order to increase the service life, the separation plate is fixed in the housing, and in the elastic bands, except for the two extreme ones, through holes are made, and in the adjacent bands, the holes are made not coincident and not intersecting, and the transitions from the groove walls in the housing to its inner surface are made in the form of a smooth curved surface. 2. A compressor according to claim 1, characterized in that the transition from the rotor surface to the groove in the rotor from the discharge nozzle side is made in the form of a bead, the surface of which, facing the housing, is made with a curvature corresponding to the curvature of the transition surface from the groove walls in the housing to its internal surface on the side of the discharge pipe. w FIG. 5 Fm.6
