    The present invention relates to a hermetic rotary compressor, and more particularly, to a high and low pressure separation device for separating a high pressure part and a low pressure part in a cylinder.
    As a general hermetic rotary compressor, as shown in Figs. 1A and 1B, there is a hermetically sealed container 1 having a predetermined internal volume. The stator 2, the rotor 3, and the like are inside the hermetically sealed container 1. It is provided with a power mechanism consisting of, the upper bearing is pressed into the inner diameter of the rotor (3) surrounding the rotary shaft (4) and the eccentric portion (4a) of the rotary shaft (4) formed with an eccentric portion (4a) at the bottom (5) and the lower bearing (6) is inserted into the cylinder (8) coupled by the bolt (7) and the eccentric portion (4a) of the rotating shaft (4) while contacting the inner diameter of the cylinder (8) Compressor mechanisms including a vane 10 and the like that linearly move and separate the inside of the cylinder into a high pressure part and a low pressure part while being in sliding contact with the rolling piston 9 and the outer circumferential surface of the rolling piston 9 are provided.
    A discharge port 8a for discharging the compressed refrigerant gas is formed at one side of the cylinder 8 forming the high pressure part by the vane 10, and the discharge port 8a is provided at one side of the upper bearing 5. The discharge hole 5a is formed in communication with.
    In addition, an inlet port 8b through which refrigerant gas flows into the cylinder 8 is formed in the low pressure part of the cylinder 8, and the inlet port 8b is an accumulator 11 installed at the side of the sealed container 1. ) And a refrigerant inlet pipe 12.
    Reference numeral 13 denotes a discharge tube through which the refrigerant gas compressed in the sealed container 1 is discharged to the outside.
    In the structure as described above, when the rotor 3 rotates while the rotor 3 rotates by the applied current, the rolling piston 9 vanes the inside of the cylinder 8 by the rotation of the rotation shaft 4. ) And the low temperature low pressure refrigerant gas introduced into the accumulator 11 by the rotation of the rotating shaft 4 and the rolling piston 9 passes through the refrigerant inlet pipe 12 and the suction port 8b. (8) sucked into the inside and compressed to a state of high temperature and high pressure, the compressed high-temperature high-pressure refrigerant gas is discharged to the outside of the cylinder (8) through the discharge port (8a) and the discharge hole (5a), which is a closed container (1) It is discharged to the outside of the compressor through a discharge pipe 13 installed in the upper portion of the.
    The vane 10 which is coupled to the eccentric portion 4a of the rotating shaft 4 in the structure of the cylinder 8 so as to be in sliding contact with the rotating piston 9 to separate the inside of the cylinder 8 into a high pressure portion and a low pressure portion. In the conventional high and low pressure separation device, as shown in Figure 1b, a compression space is formed inside the rolling piston (9) is inserted and the upper and lower bearings 5, 6 are coupled to the cylinder Guide grooves 8c are formed to penetrate to one side of the side 8, and spring insertion holes 8d are formed in which springs are inserted in the vertical length direction of the penetrated guide grooves 8c. The one end is rounded and the vane 10 having a thickness and a predetermined area inserted into the guide groove 8c is inserted into the guide groove 8c so that the rounded side contacts the rolling piston 9. The vane 10 is inserted into the guide groove 8c into which the vane 10 is inserted. A spring 14 for elastically supporting the spring is inserted into the spring insertion hole 8d. One side of the spring 14 is inserted into a groove formed at one end of the vane 10 and the other side is supported on the inner circumferential surface of the sealed container 1 to which the cylinder 8 is coupled. The spring 14 is formed of a coil spring.
    In the structure as described above, the rolling piston 9 inserted into the eccentric portion 4a of the rotating shaft 4 is eccentrically rotated inside the cylinder 8 by the rotation of the rotating shaft 4. At this time, the inside of the cylinder 8 is separated into the high pressure part and the low pressure part by the contact of the vane 10, and the refrigerant gas is sucked into the cylinder 8 by the eccentric rotation of the rolling piston 9, and the compressed gas is discharged. It is discharged through the port 8a. At this time, the vane 10 is reciprocated along the guide groove 8c by the eccentric rotation of the rolling piston 9, the vane 10 is elastically supported by the spring (14).
    However, the high and low pressure separation device of the conventional hermetic compressor as described above has a spring 14 that elastically supports the vane 10 reciprocating along the guide groove 8c by the rolling piston 8 being eccentrically rotated. In the process of repeating the contraction and expansion, as shown in FIGS. 2A and 2B, the insertion state of the spring 14 is not stabilized and wear occurs between the spring 14 and the inner circumferential surface of the spring insertion hole 8d. Not only does it cause noise, but also causes the breakage of the spring 14, the vane 10 has a problem of reducing the contact force with the rolling piston 9 causes a loss of compression.
    Accordingly, an object of the present invention is to provide a high and low pressure separating device of a hermetic rotary compressor which is in contact with a rolling piston to stabilize the coupling state of the spring supporting the vane, which divides the inside of the cylinder into a high pressure part and a low pressure part, thereby preventing the breakage of the spring.
