The housing 1 in the lower part of the injection chamber 4 has a recess 39 for the liquid, the liquid level in the UG-: baking 39 does not exceed the lower edge of the compressed gas orifice 36, and the injection chamber 4 itself has a shape and volume favorable to the primary separation coming from chambers) 3 compressing the gas-liquid mixture to gas and liquid already in the housing I of the compressor.

    In FIG. 8, the point P is a reference point, in which the volume G of the intake and compressible gas is 100 We will achieve the gas at full load and the amount L of the injected fluid is 100 (optimal for operation at full load). Curve A corresponds to the case when the volume of the injected fluid is not fully regulated. Curve B displays the allowable upper limit for the amount of injected fluid and is described by the following empirical forum: L 103 Curve C displays the lower limit of the amount of injected fluid. However, the best practical results are achieved with the lower limit corresponding to the curve D described by the following empirical formula:. 1.a A comparison of the formula formulas and an analysis of the results of the conducted research shows that the optimal ratio of the messed volumes G and L of gas and liquid is provided while satisfying the inequality L | -. G In practice, the regulation of volumes is carried out by selecting the shapes and sizes of the channel-grooves of the housing and valve and selecting the appropriate pump performance for pumping through these channels-grooves and the fluid line to the compression chambers. Rotary compressor works as follows. In accordance with changes in gas flow, temperature or pressure in reservoir 14, the control fluid from a source (conventionally not shown) is introduced under pressure through inlet port 32 or 33 into cylinder 13 and displaces piston 12 placed in it and connected with it I 1 valve 8. As a result of the movement of the valve 8 (Fig. 1), the flow area of the line formed by the channel-groove 16 of the housing 1 and the channel-groove 17 of the valve 8 is changed. In FIG. 1, a control valve 8 is immersed at full load when it is displaced so much that the grooves 16 and 17 are fully communicated with each other. Accordingly, the entire volume of fluid flowing through conduit 35 from tank 14 is injected by pump 15 through hole 45, cavity 9 and hole 10 in camera 3 squeeze. A mixture of gas and liquid from chambers Z-szh enters the chamber 4 of the injection, in which it is separated into gas and liquid, with most of the liquid collected in the recess 39, from which pump 40 is injected into the reservoir 14. All compressed gas and very small part of the liquid through the opening 36 and the check valve 38 through the pipeline 37 is also discharged into the tank 14, where the compressed gas is finally cleaned of liquid using a separator separator 42 and through the pipeline 43 is supplied to the consumer. For a second embodiment of the compressor of FIG. 3) the volume of fluid is controlled in a similar way, with the difference that the fluid enters the line through the opening 46. Depending on how much the projections 18 and 19 of the housing 1 and the valve 8 and their slots 20 and 21 are displaced relative to each other, the amount of cooling, lubricating and sealing fluid enters the compression chambers 3 through the cavity of the tubular protrusion 19, the cavity 9 and the orifice IO of the valve 8. According to the third embodiment of the compressor (Fig. 5), the protrusion 24 of the valve 8 is connected to the piston 12 and it is moved together with NSh-. (and, therefore, with the valve 8 itself) under the influence of the control medium. In this case, the protrusion 24 slides along the protrusion 23 of the body I located coaxial to it and located therein, as a result of which the flow area of the line formed by their grooves 26 and 25 and, consequently, the amount of injected fluid changes. The liquid enters the line through the hole 47, then passes through the inner cavity of the protrusion 23 of the housing 1 and through the slots 23 and 26 enters the valve cavity 9, from where it passes through the holes 10 into the compression chamber 3. Fluid is discharged in the same manner as described. In the fourth embodiment (Fig. 7), the liquid from the reservoir 14 enters the line through the opening 48 and further along the hollow protrusion 27 of the housing 1 enters the cavity 9 of the valve 8. When the regulating valve 8 is moved to change the intake gas volume, the regulating needle 28 moves with thereto, and to a greater or lesser extent, overlaps the outlet 9113 of the protrusion-channel 27, thus regulating the volume of the injected fluid. The shape of the needle 2b can be selected in a certain way to ensure optimal ratios between the controlled volumes. 2 1 3
    In this way, the invention provides an increase in the efficiency of the compressor operation by automatically maintaining the optimum ratio between the volumes of compressible gas and the cooling, lubricating and sealing fluid supplied to the compression chambers. i
