Problems solved by technology

[0013] That is, when the first metal washer is overlapped so that the surface of the first metal washer on the rib-protruding side abuts against the second metal washer, as described above, the crimping strength between the metal washer can be enhanced and the two can be improved. However, on the contrary, when the back surface of the first metal gasket on the concave side of the rib is in contact with the second metal gasket and the two are overlapped, the crimping strength between the two metal gaskets will decrease. , the tightness is also reduced
Therefore, it is important to correctly install the front and back of the metal gasket. However, in the conventional configuration, the front and back of the first metal gasket can only be judged by the shape of the rib. Even if the front and back sides are opposite, it is possible to install , therefore, there is a problem of mistakenly installing the back of the watch

Embodiment 1

[0040] Fig. 1 is a top view of a semi-hermetic compressor 1 applicable to an embodiment of the present invention, Fig. 2 is a longitudinal section front view of the compressor 1, Fig. 3 is a partial longitudinal section side view of the compressor 1, Fig. 4 is a compressor 1 is an exploded longitudinal sectional front view, FIG. 5 is an exploded partial longitudinal sectional side view of the compressor 1, FIG. 6 is a top view of the first metal gasket 13A installed on the compressor 1, and FIG. The top view of the second metal spacer 13B.

[0041]The compressor 1 of the embodiment is composed of a motor (drive element) 2 that generates rotational power, a power conversion member 3, a compression member 4, and a housing 5 that accommodates them. The power conversion member 3 converts the rotational power generated by the motor 2 to The compression part 4 is driven by the reciprocating power converted by the power conversion part 3 to compress the refrigerant (for example, natu...

Embodiment 2

[0082] In addition, even when the position of one positioning pin 65 is changed as in the above-mentioned embodiment, the positioning hole 68 is not limited to be arranged continuously with the outer rib 61B. For example, as shown in FIGS. 12 and 13, the positioning hole is arranged at The inner side of the outer rib 61B makes the two positioning holes formed on the metal spacers 13A, 13B to be in different positions when the front and the back are turned over, so that the present invention is also effective. In addition, in FIG. 12 and FIG. 13 , members assigned the same reference numerals as those in FIGS. 1 to 11 mentioned above are members having the same or similar effect or function, and description thereof will be omitted here.

[0083] The positioning hole 69 formed on the first metal washer 13A of the present embodiment is located inside the outer rib 61B, that is, it is not continuous with the rib 61B. Therefore, it is not necessary to form reinforcement around the po...

Embodiment 3

[0086] Next, another embodiment of the sealing member (the first metal gasket 13A and the second metal gasket 13B) interposed between the valve plate 5G and the casing main body 5A of the compressor 1 will be described with reference to FIGS. 14 and 15. illustrate. In this embodiment, the position of one positioning pin 65 passing through the positioning hole 67 is kept unchanged from the past, and the position of the other positioning pin 65 is changed so that the positioning hole formed on the first gasket 13A is located on the outer side of the reinforcement. The outer side of rib 61B. In addition, the compressor 1 used in this embodiment has the same structure as that of Embodiment 1 described in FIGS. 1 to 5 , FIG. 8 , and FIG. . In addition, in FIG. 14 and FIG. 15 , members assigned the same reference numerals as those in FIGS. 1 to 13 mentioned above are members having the same or similar effects or functions, and descriptions thereof are omitted here.

Abstract

The present invention provides a kind of compressor, which can really eliminate the problem that the surface and back of the formed metal shim concluding the reinforcing rib is making a mistake to install. Use a plurality of metal sheet forming at least two local holes (67, 68) to overlap to form sealing elements between the valve board (5G) and the shell body (5A). The first metal gasket (13A) of a plurality of metal gasket (13A, 13B) comprises reinforcing rib and the second metal gasket (13B) doesn't. Put the projection of the reinforcing rid of the said first metal gasket (13A) of a plurality of metal gaskets overlapping at the side of the second metal gasket (13B), and using all of the locating stud (65,66) to form location at the position that upturning the surface and the back using holes (67,68).

Description

technical field [0001] The present invention relates to a compressor in which a plurality of components are fixed to a casing main body with bolts through a seal. Background technique [0002] In the past, for example, in a reciprocating semi-hermetic compressor in which the refrigerant is compressed and worked by making the piston reciprocate in the cylinder, multiple components such as the valve plate and the cylinder head are bolted to the main body of the casing to form a casing. body. In addition, seals are provided between the cylinder head and the valve plate, and between the valve plate and the housing main body to seal between the components (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2004-301071 [0004] As a seal in this case, a gasket made of asbestos has conventionally been generally used. A cylinder hole corresponding to the cylinder formed in the housing main body, a suction port and a discharge port ...
