    A vane-type compressor especially adapted for compressing refrigerant in air-conditioning systems has a vane carrying rotor mounted on fixed center bearings and surrounded by an eccentrically positioned cylinder guiding the vane motion and confining and controlling the compression process which is free to swing toward the rotor and maintain a line of tangency contact therewith providing a direct barrier between the discharge and suction sides of the compression chamber. A spring loaded end plate pressed against one end of the cylinder serves as a relief valve to purge liquid such as lubricant which might collect in the compression cavities during a shut-down period and which could otherwise create a lock-up condition. A fixed front bearing plate or end head has a cup-shaped housing piloted thereon surrounding the cylinder and providing a rear bearing mounting for the rotor. The front plate has an inlet port supplying the compression cavities between the rotor and cylinder. The cylinder has an outlet adjacent the tangency seal line of contact between the rotor and cylinder which discharges to a chamber between the housing and cylinder that is surrounded by porous fibrous strips effective to separate lubricant entrained in the compressed refrigerant. The refrigerant is discharged to an outlet port in the front bearing plate and the separated lubricant collects in the bottom of the housing and is circulated back to the bearings and vane slots of the rotor.

    (54) ROTARY PLATE COMPRESSOR
    one
    The invention relates to a pump compressor building, namely; rotary plate compressors, mainly for automatic air conditioning systems. spirit, including the compression of the refrigerant.
    The closest to the proposed technical entity is a rotary plate compressor, | Q comprising a housing in which a cylinder is displaced and an rotor with plates placed eccentrically located in the latter, forming a vacuum chamber and a compression chamber with the cylinder and injection windows p.
    The disadvantage of this compressor is the relatively low volumetric efficiency and service life of the compressor, due to the presence of leaks and wear of the sealing components.
    The purpose of the invention is to increase the volumetric efficiency and increase the service life of the compressor.
    This goal is achieved by the fact that the cylinder is fixed on the body with the help of a hinge support installed in the zone of the discharge window.
    At the same time, a spring is placed between the housing and the cylinder in the area of the suction port, which presses the cylinder against the rotor during operation.
    Fig, 1 shows a rotary plate compressor, longitudinal section; FIG. 2 is a section A-A in FIG. I; in fig. 3 - section B - in FIG. I; in fig. 4 shows a section B-B in FIG. 2
    The rotary lamellar compressor contains a housing 1, in which the cylinder 2 is displaced and the eccentric placed in the latter is a rotor 3 with plates 4, which forms with the cylinder 2 vacuum and compression chambers connected respectively to the suction 5 and discharge 6 windows. Cylinder 2 is mounted on housing 1 by means of a ball .8 of a low support 7 installed in the area of the discharge window 6. Between case J and cylinder 2 in the area of the intake window 5 is placed a pin 8, pressing the cylinder 2 against the rotor 3 during operation. The compressor contains also an end cap 9, in which windows 5 and 6 are formed, and a shaft 10 mounted on bearings II and 12 and provided with a sealing unit 13 on which a rotor 3 with plates 4 is mounted. The hinge support 7 includes a base plate 14 having a recess 15, in which the projection 16 of the shoe 17 is located, and the console It is fixed on cylinder 2. The compressor contains a valve made in the form of a flat plate 18, cantilever-mounted between plate 14 and cylinder 2, and the latter has through holes 19 for discharging compressed refrigerant. The cylinder 2 forms with the housing 1 a crescent-shaped space divided by porous elements 20 and 21 into chambers 22 and 23. Porous elements 20 and 21 are made of a fibrous material (for example, synthetic felt) impregnated with lubricating oil and serve as a drop collector. The end cover 9 also has a channel 24 for supplying lubricating oil to the bearing 12 and the sealing unit 13, and in the cylinder 2 a groove 25 in which the spring 8 is located. The rotary plate compressor operates as follows. When the rotor 3 rotates with the plates 4 eccentrically located in the cylinder 2 with the formation of the vacuum and compression chambers connected respectively to the suction 5 and the discharge 6 windows, the refrigerant shrinks and moves from the window 5 to the window 6 o With this, the compressed refrigerant flows through the holes 19, bending the plate 18, first in to measure 22, and then to chamber 23, while passing through porous elements; - 50 in
    You are 20 and 21 and are cleared of lubricating oil, after which the purified compressed refrigerant is delivered to the consumer through the discharge port 6.

    1. US patent No. 3729277, CL. 418-107, published. 1973. 2 Separated lubricating oil accumulates in the lower part of the chamber 23, from where it passes through the channel 24 to lubricate the bearing 12 and the seal assembly 13, and then to lubricate the plates 4, the inner surface of the cylinder 2 and the bearing 11. In this case, the spring 8 placed between the housing 1 and cylinder 2 in the groove 25 of the latter, provides a constant contact of cylinder 2 with the rotor 3 at the point of contact - in the area of the suction port 5. Moreover, under the pressure of compression, cylinder 2 moves relative to the projection 16. This movement ensures that cylinder 2 is pressed to the rotor 3. Thus, both the spring 8 and the pivot bearing 7 provide intimate contact between the cylinder 2 and the rotor 3, which is sufficient to prevent leakage, while at the same time reducing Fr loss. The proposed improvements provide improved volumetric efficiency and increased service life of a rotary vane compressor. Formula I. A rotary plate compressor, comprising a housing in which a cylinder is displaced and an rotor with plates eccentrically disposed in the latter, which forms, with a cylinder, a vacuum chamber and a compression chamber, respectively connected to the suction and discharge ports, in order to increase volumetric efficiency and increase the service life of the compressor, the cylinder is mounted on the housing with a hinge support installed in the area of the discharge window.
