Description

[0001] SCROLL COMPRESSOR [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a scroll compressor, and more particularly, to a scroll compressor in which a tip chamber structure is improved so as to allow axial flow of an orbiting scroll while maintaining airtightness of the compression chamber.

Generally, compressors that serve to compress refrigerant in automotive cooling systems have been developed in various forms. Such a compressor includes a reciprocating type in which compression is performed while a refrigerant is compressed and a rotary type in which compression is performed while rotating. In the reciprocating type, there are a crank type in which the driving force of the drive source is transmitted to a plurality of pistons by using a crank, a swash plate type in which the swash plate is transmitted by a swash plate installed shaft, a wobble plate type in which a wobble plate is used, There are vane rotary type, scroll type using revolving scroll and fixed scroll.

FIG. 1 shows the construction of a conventional scroll compressor, and FIG. 2 shows a conventional tip chamber and orbiting scroll. 1 and 2, a scroll compressor according to an embodiment of the present invention includes a housing 10 in which a compressor 10, a compressor 30, and a controller 40 are installed. The compression chamber 60, the discharge chamber 70, and the back pressure chamber 80 are partitioned by the suction chamber 50, the suction chamber 50, the compression chamber 60, the discharge chamber 70,

The driving unit 20 includes a stator 21 and a rotor 22 coaxially mounted on the inside of the housing 10 and the compression unit 30 is fixed to the inside of the housing 10 And an orbiting scroll (32) that forms a compression chamber (60) by engaging with the fixed scroll (31) while pivotally moving by the drive unit (20), and the control unit And various types of driving circuits and elements mounted on the inner side of the housing 10.

The suction chamber 40 is a space in which the refrigerant sucked from the outside of the housing 10 is stored and the compression chamber 50 is a space in which the refrigerant sucked into the suction chamber 40 is compressed, (60) is a space through which the refrigerant compressed in the compression chamber (50) is discharged, and the back pressure chamber (80) is a space for applying pressure such that the orbiting scroll (32) is in close contact with the fixed scroll .

When the external power is applied to the control unit 40 through the connection terminal or the like, the controller 40 controls the driving unit 20 to supply the operation signal .

When the operating signal is transmitted to the driving unit 20, the electromagnet type stator 21 which is press-fitted into the inner peripheral surface of the housing 10 is excited and becomes magnetized, So that the rotor 22 rotates at a high speed.

At this time, when the rotary shaft 23 of the driving unit 20 rotates at a high speed, the orbiting scroll 32 of the compression unit 30 coupled to the rear end of the rotary shaft rotates at high speed in synchronism with each other, The refrigerant that has flowed from the suction chamber 50 to the compression chamber 60 is compressed from the outer periphery of the scroll to the scroll center by the interaction with the fixed scroll 31 and discharged to the discharge chamber 70 The refrigerant compression operation is completed.

The refrigerant discharged to the discharge chamber 70 is delivered to the outside of the housing 10 and a part of the refrigerant is reduced in pressure through the orifice and then transferred to the back pressure chamber 80, A pressure is generated in the back pressure chamber 80 by the transferred refrigerant and a back pressure plate (not shown) abutting on the orbiting scroll 32 by the pressure of the back pressure chamber 80 presses the orbiting scroll 32 The orbiting scroll 32 is pressed in the direction of the fixed scroll 31 and the orbiting scroll 32 and the fixed scroll 31 are closely contacted with each other so that the compression chamber 60 can be sealed. A ring-shaped tip chamber T is provided at the contact portion between the back pressure chamber 80 and the orbiting scroll 32 so as to prevent the refrigerant from leaking at the contact portion between the back pressure chamber 80 and the orbiting scroll 32 .

On the other hand, in order for the refrigerant compression process to proceed smoothly, the orbiting scroll 32 should be rotated without rotating. To this end, a rotation prevention mechanism for preventing the rotation of the orbiting scroll 32 is installed on the rear portion of the orbiting scroll 32. In the conventional case, as shown in FIG. 1, And a pin member P which is installed in the housing 10 and is inserted into the ring member R. The ring member R, which moves together with the orbiting scroll 32, The rotation of the orbiting scroll 32 can be prevented by restricting the movement of the orbiting scroll R by the pin member P. [

However, in the above-described conventional scroll compressor structure, the tip room T provided at the contact portion between the back pressure chamber 80 and the orbiting scroll 32 does not have the axial flame damping function. Accordingly, axial flow of the orbiting scroll 32 is restricted, excessive stress concentration may occur in the orbiting scroll 32, and when the excessive stress concentration occurs, the orbiting scroll 32 is deformed and the compression efficiency is lowered .

SUMMARY OF THE INVENTION The present invention has been proposed in order to solve the above-mentioned problems, and it is an object of the present invention to provide a damping tip chamber having a damping function, which enables axial flow of the swivel scroll to prevent deformation of the orbiting scroll due to stress concentration, And it is an object of the present invention to provide a scroll compressor capable of solving the problem of deterioration in compression efficiency.
