In different specifications of the compressors, the common ones include models such as rotary compressors, scroll compressors and screw compressors.
- The scroll compressor incurs a relatively higher cost due to its high level of difficulty of manufacture. Although both of the rotary compressor and the screw compressor complete the compression by changing the volume of the compressor chamber, yet the rotary compressor adopts a simple compression method and skillfully avoids the problems of the screw compressor including the deviation of the force in an axial direction, clearance volume and internal leakage, so as to improve the reliability and efficiency of the device and obtain a relatively higher market share.

If the casing of the rotary compressor is tilted, the refrigerant in the second chamber will flow to the first chamber, and if the casing of the rotary compressor resumes to its normal using position, the refrigerant will flow to the first chamber and cannot reflow to the second chamber, so as to affect the overall operation performance of the compressor adversely and reduce the efficiency of the compressor. In addition, thecylinder 14 and thecasing 11 are fixed by soldering, and this it is necessary to melt the metal at a soldering point of thecylinder 14 and thecasing 11, and the soldering process generally requires a high temperature over 1000. The high temperature of the soldering may cause a deformation of thecylinder 14 easily and affects the precision of a micro-scale inner wall of thecylinder 14 significantly. As a result, the cylinder may leak or get stuck easily, particularly for a smaller rotary compressor, and the aforementioned thermal deformation issue is inevitable. - Therefore, it is a primary objective of the present invention to provide a rotary compressor capable of isolating high and low pressures.
- To achieve the aforementioned objective, the present invention provides a rotary compressor comprising a casing having a motor, an eccentric shaft and a cylinder installed therein, and the motor includes a rotor and a stator, and the eccentric shaft rotates with the rotor and turns around in the cylinder, and the cylinder divides the casing into a high pressure chamber and a low pressure chamber, and the high pressure chamber is disposed between the motor and the cylinder, and the low pressure chamber is disposed at the bottom of the cylinder, wherein an isolating element is installed between the cylinder and the casing for isolating the high pressure chamber and the low pressure chamber, and the isolating element includes at least one reflowing hole penetrated through the isolating element and interconnected between the high pressure chamber and the low pressure chamber.
