産業上の利用分野
本発明は、空気や冷媒を吸入し圧縮、吐出する密閉型回
転式圧縮機の吐出通路に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a discharge passage of a hermetic rotary compressor that takes in, compresses, and discharges air or refrigerant.
従来例の構成とその問題点
従来、この種の密閉型回転式圧縮機は、第３図に示すよ

冷媒ガスの吐出が激しく行われ、この爆発的な吐出のた
めに圧縮機の騒音及び振動が大きくなっていた。However, in this conventional configuration, since the valve seat 27 is flat, lubricating oil (not shown) easily adheres to it, and the surface tension of this adhered lubricating oil is large, making it difficult to open the discharge valve 26. , overcompression increased, and when the discharge valve 26 was opened, the refrigerant gas was violently discharged, and this explosive discharge increased the noise and vibration of the compressor.

冷媒の吐出を制御し、圧縮機の騒音及び振動を低減する
ことを目的とするものである。OBJECT OF THE INVENTION The present invention solves the above-mentioned conventional problems, and controls the discharge of explosive refrigerant by increasing the responsiveness of the discharge valve and suppressing overcompression, thereby reducing the noise and vibration of the compressor. The purpose is to reduce
発明の構成
この目的を達成するために、本発明は弁座から吐出穴側
面にかけて、単数あるいは複数の切欠を設けたものであ
る。Structure of the Invention In order to achieve this object, the present invention provides one or more notches from the valve seat to the side surface of the discharge hole.

面張力が作用しないため、吐出弁の応答性は良くなり、
過圧縮が抑制され吐出ガス原音が小さくなり、圧縮機の
騒音および振動が低減するものである。With this configuration, the surface tension of the lubricating oil does not act between the discharge valve and the notch, so the response of the discharge valve is improved.
Overcompression is suppressed, the original sound of discharged gas is reduced, and noise and vibration of the compressor are reduced.

る。In the figure, 1 is a closed container, inside which is a rotor 2.
and a stator 3, and a compressor element 6 driven by the motor element 4 via a crankshaft 5. The compressor element 6 includes a piston 7 integrated with the crankshaft 5, a cylindrical cylinder 8 housing the piston 7, and the cylinder 8.
It is composed of an upper bearing end plate 9 and a lower bearing end plate 10 that close openings at both ends. These upper and lower bearing end plates 9 and 10 are
Each of them forms a pair and also serves to support the crankshaft 5. A discharge device 11 is provided on the upper bearing end plate 9 .
次に、第２図により上記吐出装置１１の構成について説
明する。ここで第１図と同じものについては同一の番号
を付して説明を省略する。Next, the configuration of the discharge device 11 will be explained with reference to FIG. Here, the same parts as in FIG. 1 are given the same numbers and the explanation is omitted.
同図において、吐出装置１１は上軸受端板９に吐出穴１
２を設け、この吐出穴側面１３と吐出弁１４が閉塞時に
当接する平面形状の弁座１５にかけて数個の切欠１６を
設けた構成となっている。In the figure, the discharge device 11 has a discharge hole 1 in the upper bearing end plate 9.
2, and several notches 16 are provided between the discharge hole side surface 13 and the planar valve seat 15 that the discharge valve 14 comes into contact with when the discharge valve 14 is closed.
上記構成において、電動機要素４が運転されると、圧縮
機要素６も駆動され、冷媒はシリンダ８内に吸込まれ、
ピストン７の回転に伴なって圧縮され、圧力が上昇する
と、吐出弁１４を押し上げてシリンダ８から吐出しよう
とする。In the above configuration, when the electric motor element 4 is operated, the compressor element 6 is also driven, and the refrigerant is sucked into the cylinder 8.
As the piston 7 rotates, it is compressed and the pressure increases, pushing up the discharge valve 14 and attempting to discharge from the cylinder 8.
この時、吐出穴側面１ａと弁座１５にかけて切欠を設け
ているために、この部分には潤滑油（図示せず）による
吐出弁１５の開きを妨げる表面張力が作用せず、吐出弁
１５の応答性がよくなり、無用なシリンダ８内圧力の上
昇（過圧縮）を抑制でき、爆発的なガスの吐出が抑制さ
れ、吐出ガスによる騒音、振動が低減する。また、過圧
縮を抑制することによる入力低減の効果も得ることがで
きる。At this time, since a notch is provided between the discharge hole side surface 1a and the valve seat 15, surface tension that prevents the discharge valve 15 from opening due to lubricating oil (not shown) does not act on this part, and the discharge valve 15 opens. Responsiveness is improved, unnecessary increase in pressure inside the cylinder 8 (overcompression) can be suppressed, explosive discharge of gas is suppressed, and noise and vibration caused by discharged gas are reduced. Moreover, the effect of input reduction can also be obtained by suppressing overcompression.
