Gas compressor

Abstract

The present invention provides a gas compressor that can reduce the cost of the entire gas compressor without reducing the oil separation performance required by the gas compressor and can maintain the same oil separation function for a long time. This gas compressor is provided with an oil separator with a pipe structure consisting only of a discharge pipe integrally formed with a side cylinder head, which is used to separate lubricating oil components contained in high-pressure refrigerant gas out of the device. In this case, the discharge pipe is used as a discharge path for the high-pressure refrigerant gas from the first discharge chamber straight to the front of the inner wall of the compressor housing without a bypass. The separation of lubricating oil components is achieved by the high-pressure refrigerant gas that has just been discharged into the first discharge chamber from the cylinder discharge port flows through the discharge pipe and collides with the inner wall of the compressor housing without reducing the high flow rate.

Description

technical field [0001] The present invention relates to a gas compressor installed in a vehicle or other system, and more particularly to a gas compressor that can maintain the same function for a long time without degrading the oil separation function required for the compressor. A gas compressor that can reduce the cost of the entire compressor without changing the oil separation function. Background technique [0002] In this type of traditional gas compressor, as shown in Figure 11, there is a cylinder 2 whose inner circumference is basically elliptical in the compressor housing 1, and cylinder heads are installed on the two end faces of the cylinder 2 respectively. 3, 4. [0003] In the gas compressor shown in the same figure, the casing 1 is composed of a box body 1-1 with one end open and a front end cover 1-2 installed at the open end. The second discharge chamber 5 and the suction chamber 6 are located inside the housing 1 . The second discharge chamber 5 is loca...

Problems solved by technology

Therefore, if any failure occurs due to the loosening of the oil separator lock bolt 26, for example, when the lock bolt 26 is loose, the installation reference plane of the side cylinder head 3 and the oil separator 20 is opened, thereby blocking the gas passage 19, Before the oil is separated, the high-pressure refrigerant gas leaks from the gap to the outside of the gas passage 19, resulting in a decrease in oil separation performance, etc.

In other words, it is difficult to maintain the same oil separation function for a long time
