産業上の利用分野
本発明は、冷蔵庫等に使用される圧縮機に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a compressor used in refrigerators and the like.

近年圧縮機は、省エネルギー化及び省資源化の見地から
高効率化が要望され続けている。圧縮機は高効率化が進

直して一層の高効率化を計ってゆかなければならない。BACKGROUND OF THE INVENTION In recent years, compressors have been required to have higher efficiency from the standpoint of energy and resource conservation. Compressors are becoming more efficient and have reached a high level, but we must review both the big picture and the details to make them even more efficient.

示されている。The conventional compressor mentioned above will be explained below with reference to the drawings. FIG. 4 shows a sectional view of the head of a cylinder in which valves are attached in a conventional compressor. Fourth
In the figure, 1 is a cylinder, and 2 is a piston that reciprocates within the cylinder. 3 is a suction reed valve, 4 is a valve plate, 5 is a discharge reed valve, 6 is a gasket,
Reference numeral 7 denotes a head cover consisting of a single-plate substrate 7a joined by brazing and a cover 7b made of a drawn product, both of which are bolted to the cylinder 1 in this order. The substrate 7a of the head cover 7 is provided with a concave valve receiver portion 7C for regulating the lift amount of the discharge reed valve 6. Further, 8 is a resin suction muffler. The operation of the compressor configured as above will be explained below. First, the gas sucked from the suction muffler 8 is
The gas is sucked into the cylinder 1 through the suction reed valve 3 and compressed by the reciprocating movement of the piston 2,
Compressed gas is sent into the head cover 7 through the discharge reed valve 6. At this time, the amount of lift of the discharge reed valve 6 is determined by the plate thickness of the gasket 6 plus the valve receiving portion 70 of the base plate 7a of the head cover 7. The thicker the gasket 6 is, the more it will sag due to heat and tightening force, and the sealing performance will be extremely reduced. In addition, the larger the lift amount of the discharge reed valve 5, the lower the press-fitting loss.
A concave valve receiver portion 7C was provided on the base plate 7a. Incidentally, such a conventional example is shown in Patent Application Publication No. 74380/1980.

点を有していた。Problems to be Solved by the Invention However, in the above configuration, there is a limit to the step machining of the part 70 of the base plate 7a of the head cover 7 made of iron plate and the valve receiver, and the part 7c of the valve receiver is still limited to the part 7c of the discharge reed valve. It is very difficult to mold it into a shape that follows the lift shape of No. 6. Furthermore, since the direction in which the compressed gas is most easily discharged is blocked from the viewpoint of the flow of the compressed gas, there is a problem in that the shape has a large passage resistance.
本発明はこのような従来の問題点を解消するものであシ
、より吐出側の圧力損失低減をはかシ高効率化を実現す

抗を感じることとなる。Effect of the Invention With the above-described configuration, the present invention further expands the lift amount of the discharge reed valve, and makes it easy to form the valve receiver into a shape that follows the lift shape of the discharge reed valve. Moreover, since there is no part of the valve receiver in the direction in which the compressed gas flows out the most, passage resistance will be felt.

７ト形状に沿った形状に成形されている。In the figure, numeral 9 denotes a head cover in which a board 9a made of a single plate and a cover 9b made of a drawn product are bonded together by brazing. The substrate 9a is provided with a valve receiver portion 9c for receiving the discharge reed valve 5, and the valve receiver portion 9C is punched out into a substantially U-shape and bent outward to fit the discharge reed valve 5 glue 7 shape. It is molded into a shape.

ラドカバ−９の基板９ａが無い為、通路抵抗を減する事
ができる。The operation of the compressor configured as above will be explained below. Gas sucked into the cylinder 1 from the suction 77ler 8 via the suction reed valve 3 is compressed by the reciprocating movement of the piston 2 and is discharged into the head cover 9 via the discharge reed valve 5. Since the valve receiver part 9c of the head cover 9 follows the shape of the discharge reed valve 6, the discharge reed valve 6 can be opened and closed smoothly, and the valve receiver 9c is arranged in the direction in which discharge is most easily discharged into the head cover 9. Since there is no substrate 9a of the helad cover 9, the passage resistance can be reduced.

きる。As described above, according to this embodiment, the portion 9c of the valve receiver is approximately U.
By punching out a letter shape and bending it into a shape that follows the shape of the glue 7 of the discharge reed valve 6, the discharge reed valve 6 can be opened and closed smoothly, and the compressed gas can flow into the head cover 9. Passage resistance during discharge can be reduced.
