Compressor

Abstract

An object is to inhibit a refrigerant leakage and enhance a performance of a compressor. The compressor comprises a driving element stored in a sealed container of the compressor, and a compression element driven by a rotary shaft of the driving element. This compression element comprises a cylinder in which a compression space is constituted; a suction port and a discharge port which communicate with the compression space in the cylinder; a compression member whose one surface crossing an axial direction of the rotary shaft is inclined continuously between a top dead center and a bottom dead center and which is rotatably disposed in the cylinder and which compresses a fluid (refrigerant) sucked from the suction port to discharge the fluid via the discharge port; and a vane which is disposed between the suction port and the discharge port to abut on an upper surface as one surface of the compression member and which partitions the compression space in the cylinder into a low pressure chamber and a high pressure chamber, and one surface of the compression member is disposed on a side opposite to the driving element.

Description

[0001] This application is a divisional application of the application titled "compressor" and application number 2005101071749 filed by Sanyo Electric Co., Ltd. on September 28, 2005. technical field [0002] The present invention relates to a compressor for compressing and discharging fluids such as refrigerant and air. Background technique [0003] Conventionally, for example, in refrigerators, a method in which a compressor compresses a refrigerant and circulates the refrigerant in a circuit is used. Examples of such compressors include a rotary compressor called a rotary compressor (see, for example, JP-A-5-99172, Document 1), a scroll compressor, and a screw compressor. [0004] The above-mentioned rotary compressor has the advantages of relatively simple structure and low manufacturing cost, but has the problems of large vibration and torque fluctuation. In addition, scroll compressors and screw compressors have problems of difficulty in processing and high cost, alt...

Problems solved by technology

[0006] However, in the structure of the above-mentioned document 2, since the high-pressure chamber and the low-pressure chamber are formed adjacent to the upper and lower sides of the compression member (swash plate) in the entire cylinder, there is a problem of poor efficiency caused by refrigerant leakage due to an increase in the high-pressure and low-pressure differences. question

[0007] In particular, when one side of the compression member is arranged on the side of the driving element, the refrigerant in the compression space tends to leak from between the rotating shaft and the bearing of the rotating shaft, resulting in a decrease in the performance of the compressor.

[0008] In addition, in the compressor of the above-mentioned document 2 structure, also like the current compressor of the above-mentioned document 1, an oil collecting pan is formed in the lower part of the airtight container, and oil is supplied from the oil collecting pan to the compression element through an oil pump. , For example, when the compression element is arranged on the upper side of the driving element, etc., and the compression element is installed at a position away from the oil pan, it is difficult to supply oil through the oil pump, resulting in insufficient oil supply.
