As shown in FIG. 1, the reciprocating type hermetic compressor has a piston 5 of a cylinder device 4 connected to a crank portion of a shaft 3 of an electric motor that is rotatably supported by a frame 2 provided in a hermetically sealed case 1. The reciprocating motion compresses the refrigerant gas led from the suction pipe 6, and the compressed refrigerant gas is guided to a heat exchanger (not shown) by the discharge mantle 9 via the discharge chamber of the valve cover 7 and the muffler chamber 8. There is.

However, the valve cover 7 of the above type has cover members 13 and 14 joined together as shown in FIG.
The passage portion 16 formed by the notch is formed at a position offset by the notch, and the passage portion 16 is bent at right angles. Therefore, it is difficult to align both cover members at right angles, resulting in poor workability and limited capacity. When incorporated into a compressor with a large capacity, there is a problem in that the passage area becomes insufficient, which causes a decrease in compressor performance.
本発明は上記した点に鑑みてなされたもので、
カバー部材接合時の直角合わせを容易に行ない得

The present invention provides an opening in the passage forming part of the cover member to be joined, and forms a plurality of connecting parts to vary the passage area, and also facilitates right angle alignment by joining two or more separated parts. It was designed so that it could be carried out.
以下本発明の一実施例を図面につき説明する。 An embodiment of the present invention will be described below with reference to the drawings.
なお第６図において第５図と同一部材について
は同一符号を付す。 In FIG. 6, the same members as those in FIG. 5 are given the same reference numerals.
第６図において符号２０はマフラ室１８と吐出

されている。 In FIG. 6, reference numeral 20 is a refrigerant passage connecting the muffler chamber 18 and the discharge chamber 12, and this passage 20
are formed on both sides sandwiching the opening 21 provided in the middle part.
すなわちカバー部材１３の通路形成部２２の中

る。 That is, by providing the opening 21 in the center of the passage forming part 22 of the cover member 13, two connecting parts are formed on both sides, and the passage 20 is formed in these two connecting parts. Then, the cover member 13 is bent and formed at right angles at the passage forming portion 22 by conventional means.
一方、カバー部材１４も上記カバー部材１３の
開口２１に対応した部位に開口が設けられ、同じ

うことができる。 However, when assembling the valve cover 7,
The cover member 13 and the cover member 14 are joined so that the openings 21 overlap, and both the covers 13 and 1
4 are integrally joined by copper brazing (or silver brazing). Since the bent portions of both the cover members 13 and 14 are joined at the two connecting portions, the two cover members can be aligned at right angles smoothly and easily.
第８図は本発明の他の実施例を示すものであつ
