Description

[Brief explanation of the drawing]

FIG. 1 is a cross-sectional view of a rotary compressor equipped with a lubricating oil cooling circuit according to the present invention, and FIG. 2 is a partial perspective view showing a main part of FIG. 1 partially cut away. 1 is a closed container, 2 is a compression element, 4 is a cylinder, 5 is a piston, 6 is a crankshaft, 7 is a main bearing, 8 is an end bearing, 1
4 is a discharge pipe, 15 is lubricating oil, 16 is an oil guide pipe, and 17 is a heat exchanger.

Claims (1)

[Scope of utility model registration request] The inside of the cylinder is divided into a high pressure side and a low pressure side by vanes and pistons, and compression is performed by rotation of the crankshaft.
The compression element that discharges the high-pressure gas from the main bearing or end bearing in contact with both end surfaces of the cylinder, or the discharge hole provided in the cylinder is housed in a sealed container that serves as a high-pressure space, and the gas is stored in the sealed container. In a rotary compressor equipped with a circuit that lubricates each sliding part of the compression element with oil, and guides the oil stored at the bottom of the container to a heat exchanger outside the closed container and returns it into the container. , one end of the oil guide pipe to the heat exchanger is opened in the lubricating oil in the closed container, and the discharge pipe for the compressed gas is inserted and released into the oil guide pipe, and the lubricating oil is injected by injecting the discharge gas. A rotary compressor characterized in that circulation is circulated through the heat exchanger and into a closed container.
