Problems solved by technology

[0008] In the structure disclosed in Publication No. 11-107959 - in which the compressed refrigerant gas discharged into the discharge space directly enters the discharge pipe through the hole, is separated from the refrigerant gas by the hole and attached to the surface of the pipe adjacent to the hole The lubricant may block the refrigerant gas flow through the hole, which is disadvantageous in terms of preventing the pressure loss of the refrigerant gas from increasing due to the throttling of the refrigerant gas flow by means of the hole

Embodiment Construction

[0018] Embodiments of an electric motor driven compressor according to the present invention will be described below with reference to the accompanying drawings. Figure 1 to Figure 4 An electric motor driven scroll compressor according to a first embodiment of the present invention is shown. It should be noted that the compressor's as in figure 1 The left and right sides observed in , correspond to the front and rear sides of the compressor, respectively, and the figure 1 The upper and lower sides viewed in correspond to the upper and lower sides of the compressor, respectively.

[0019] refer to figure 1 , the compressor has a front casing 1 and a rear casing 2 which are fixed together by a plurality of bolts 3 to form a sealed compressor casing. The rear case 2 and the front case 1 respectively have an inlet port 4 and an outlet port 5 connected to an external refrigerant circuit (not shown). Refrigerant gas enters the compressor through the introduction port 4 of the r...

Abstract

A compressor includes a housing having a discharge chamber into which compressed refrigerant gas is discharged, an oil separation chamber, a passage connecting between the discharge chamber and the oil separation chamber, and an outlet port through which the refrigerant gas passed through the oil separation chamber flows out of the housing; and a cylindrical oil separator provided in the oil separation chamber. The oil separator includes a large-diameter portion, a small-diameter portion, and an intermediate portion formed between the large-diameter portion and the small-diameter portion and tapered toward the small-diameter portion. Plural holes are formed in the periphery of the small-diameter portion of the oil separator. The passage is directed toward the small-diameter portion of the oil separator in such a manner that the refrigerant gas swirls around the small-diameter portion, so that the refrigerant gas from which lubricating oil is separated enters the oil separator through the hole.

Description

technical field [0001] The present invention relates to a compressor. Background technique [0002] Pulsations of the discharged refrigerant gas occur in the refrigerant gas compressor. When the compressor is used in a vehicle air conditioner, this pulsation is transmitted to the cabin of the vehicle through the piping of the refrigerant circuit, and causes vibration and abnormal noise of equipment in the cabin. In order to reduce this pulsation, various methods have been proposed, such as providing a large-volume muffler on the side where the refrigerant gas is discharged or throttling the flow path of the discharged refrigerant gas. [0003] However, providing a large-volume muffler leads to an increase in the size of the compressor and thus to an increase in the installation space of the compressor, which is disadvantageous for installation in an environment such as a vehicle in which the arrangement space is limited. Throttling the refrigerant gas passage to reduce the...
