Description

Scroll Compressor

The present invention relates to a scroll compressor having an oil supply assembly.

A scroll compressor is a compressor which compresses refrigerant gas by changing the volume of a compression chamber formed by a pair of opposed scrolls. Scroll compressors have higher efficiency, lower vibration and noise, smaller size and lighter weight than reciprocating compressors or rotary compressors, and thus are widely used in air conditioners.

In general, the scroll compressor can be divided into low pressure and high pressure according to the pressure of the refrigerant filling the inner space of the casing. In the low pressure scroll compressor, a suction pipe communicates with the inner space of the casing, and a discharge pipe communicates with the discharge side of the compression unit so that the refrigerant is indirectly sucked into the compression chamber. On the other hand, in the high pressure scroll compressor, the suction pipe is in direct communication with the suction side of the compression unit, and the discharge pipe is in communication with the inner space of the casing so that the refrigerant is directly sucked into the compression chamber.

In the case of such a high pressure scroll compressor, the refrigerant discharged from the compression unit is filled in the casing inner space. In addition, the high-pressure scroll compressor has a fixed scroll, a swinging scroll engaged with the fixed scroll to compress the refrigerant, a main frame supporting the swinging scroll, and a fixed scroll fixed to the main frame, that is, on the back of the swinging scroll. The back pressure chamber which forms intermediate pressure is formed. In the back pressure chamber, the oil drawn up through the oil flow path of the drive shaft combined with the swing scroll is introduced into the back pressure chamber through the bearing surface between the main frame and the swing scroll through the oil storage groove of the main frame. The back pressure chamber forms an intermediate pressure because the pressure is reduced while passing through the bearing surface between the wheel and the turning scroll. Since the pressure in the back pressure chamber is higher than the pressure in the suction chamber, the oil in the back pressure chamber flows into the suction chamber through the bearing surface between the fixed scroll and the swing scroll by the pressure difference and is supplied to the compression chamber. In this process, the bearing surface between the fixed scroll and the swing scroll is lubricated to reduce the friction loss of the compressor.

However, there is a problem in that the structure for supplying the oil of the scroll compressor is complicated, and thus, the process and the cost are high.

In addition, during the initial operation or the low speed operation of the scroll compressor there is a problem that the oil is not supplied smoothly to the bearing surface between the fixed scroll and the swing scroll to reduce the efficiency of the compressor due to friction loss.
