れが圧縮機の騒音増大につながっておりこの点に関して
も問題があった。In manufacturing valve plates for conventional valve devices of hermetic compressors, most of them have the structure shown in Figures 1 and 2, and are manufactured by machining a cast material, and this machining requires a flat surface. Strict accuracy and complicated machining such as valve relief groove machining, drilling, etc. are required, requiring advanced technology and time.On the other hand, even when combined with a valve, it requires a lot of time to attach with screws or rivets. Many defects were caused by screws loosening and breaking, and the impact caused by the collision between the valve and valve plate was also large, which led to increased noise from the compressor, which was another problem.
本考案は上述問題点を解消すべく改良するもので以下図
示一実施例に従って詳細に説明する。The present invention is an improvement to solve the above-mentioned problems, and will be described in detail below according to an embodiment shown in the drawings.
第３図は本考案の密閉形圧縮機の弁装置の一実施例分解
斜視図、第４図は第３図のＢ−Ｂ’断面図である。FIG. 3 is an exploded perspective view of an embodiment of the valve device for a hermetic compressor according to the present invention, and FIG. 4 is a sectional view taken along line BB' in FIG. 3.
尚第１図及び第２図と同一部品は同一符号を記す。Components that are the same as those in FIGS. 1 and 2 are designated by the same reference numerals.
図において、１はバルブプレートにして、スウエーテ゛

出穴２、吸入穴３及び弁逃げ溝４を設けたものを製作す
る。In the figure, reference numeral 1 denotes a valve plate, which is manufactured using a thin steel plate such as swathed steel or spring steel and provided with a discharge hole 2, a suction hole 3, and a valve escape groove 4 by press working.
このバルブプレート１に吐出弁５、吸入弁６をスポット
溶接Ａ等を施こし一体形威している。A discharge valve 5 and a suction valve 6 are integrally formed on this valve plate 1 by spot welding A or the like.
そして前記バルブプレート１に内部摩擦の大きい緩衝材
７（例えばテフロン等の樹脂が適している。A cushioning material 7 (for example, a resin such as Teflon or the like) having a large internal friction is suitable for the valve plate 1.
）を接着によりサンドイツチ構造として結合している。) are bonded together as a sanderch structure by adhesion.
尚、第１図中８は吐出弁５の開或動作を規制するりテー
ナーである。In addition, 8 in FIG. 1 is a retainer for regulating the opening or operation of the discharge valve 5.
従って、気体の吸い込み時には吸入弁６の遊端部が内方
に彎曲し、吸入穴３より気体を吸い込むと共に、圧縮時
には上記吸入弁６が閉或して吐出弁５の遊端部が外方に
彎曲し、吐出穴２より圧縮気体を吐出する。Therefore, when gas is sucked in, the free end of the suction valve 6 bends inward to suck in gas from the suction hole 3, and when compressed, the suction valve 6 is closed and the free end of the discharge valve 5 is bent outward. The compressed gas is discharged from the discharge hole 2.
この時、上記吸入弁６及び吐出弁５は圧力差、気体の流

ーナ−８やストッパー（図示せず）との間に衝撃音を発
生するが、この衝撃音は緩衝材７によって吸収されるた
め騒音がなくなる。At this time, the suction valve 6 and the discharge valve 5 repeat opening and closing several times due to the pressure difference and gas flow, and the movement of the suction valve 6 and the discharge valve 5 is restricted as well as between the valve plates 1 and 1. -8 and a stopper (not shown), but this impact sound is absorbed by the cushioning material 7, so there is no noise.
又、バルブプレート１，１と弁５，６とは溶接されてい
るためビス止めやリベット止めに比して耐強度性が良好
となり商品信頼性も高く、ビス、リベット等の緩みによ
るガタツキもなくなるものである。In addition, since the valve plates 1, 1 and the valves 5, 6 are welded, they have better strength resistance than screws or rivets, and product reliability is high, and there is no wobbling due to loosening of screws, rivets, etc. It is something.

るという顕著な効果を奏し得るものである。As described above, in the present invention, the valve plate of the hermetic compressor is made of a thin steel plate such as swath steel or spring steel, and this valve plate is arranged on the discharge valve side and the suction valve side, and each The discharge valve and suction valve are welded to the outer surface of the valve plate, and a buffer material made of a material with high internal friction such as resin is interposed between the two valve plates, which requires complicated machining. It is possible to shorten the machining time by eliminating the need for screws, rivets, etc. when assembling the valve, making it inexpensive and highly reliable. Furthermore, since a cushioning material is interposed between the two valve plates, the generation of impact vibrations is reduced, and the noise of the compressor can be reduced. It is.
