Problems solved by technology

[0004] However, in the conventional structure, since the flow limitation depends on the size of the helical passage formed on the outer periphery of the main body, the processing precision of the helical passage is required to be high, and there is a problem that processing is difficult.

Embodiment Construction

[0027] Hereinafter, one embodiment of the present invention will be described based on the drawings.

[0028] exist figure 1 Among them, reference numeral 1 denotes a scroll compressor constituting an internal high pressure, and the compressor 1 is connected to a refrigerant circuit outside the figure, and is used to compress refrigerant, and the refrigerant circulates in the refrigerant circuit to perform refrigeration cycle operation . This compressor 1 has a vertically elongated cylindrical hermetic dome casing 3 .

[0029] The shell 3 is composed of a shell body 5, a bowl-shaped upper cover 7, and a bowl-shaped lower cover 9 to form a pressure vessel, and a cavity is formed inside. The housing body 5 is a cylindrical base part with an axis extending in the up-down direction; the upper cover 7 is integrally welded to the upper end of the housing body 5 in an airtight manner, and has a convex surface protruding upward; the lower The cover 9 is integrally welded to the low...

Abstract

The invention provides a scroll type compressor that can restrict the flow rate of lubricating oil without requiring a high processing precision and can be manufactured in low cost. An intercommunication path (51) for supplying a lubricating oil to a low-pressure portion (35A) in a scroll is arranged in a movable scroll (25). One end of the intercommunication path is opened to the outside and linearly extends inside. A high-pressure opening (51D) communicated with a high-pressure portion (43) in a sealed container and a low-pressure opening (53) opened to the low-pressure portion (35A) in the scroll are disposed on an inner peripheral surface. The intercommunication path (51) is configured as follows: a bottom hole (51A) opened to the outside at one end is formed; and reaming processing is conducted from one end to a position of a predetermined depth H on the lower hole (51A) to form an insertion hole (51B). A pin member (55), which is abutted against the inner end of the bottom hole (51A)and set to be smaller than the diameter of the insertion hole (51B), is inserted in the intercommunication path (51); the pin member (55) is extruded to the inner end so as to close the one end of the intercommunication path by a screw member (57).

Description

technical field [0001] The present invention relates to a scroll compressor having an oil passage for supplying lubricating oil to a meshing portion of a fixed scroll and a movable scroll on a low pressure side. Background technique [0002] Generally, there is known a scroll compressor in which a fixed scroll and a movable scroll meshing with the fixed scroll are accommodated in a hermetic container. Among such scroll compressors, there is proposed a scroll compressor having an oil passage for supplying lubricating oil to the meshing portion of the low-pressure side of the fixed scroll and the movable scroll, and in the oil passage A flow rate limiting member having a main body having a helical passage formed on the outer periphery is arranged (for example, refer to Patent Document 1). [0003] Patent Document 1: (Japanese) Unexamined Patent Publication No. 2004-60532 [0004] However, in the conventional structure, since the flow restriction depends on the size of the he...
