本発明は冷蔵庫、シコケース等の冷却システムに用いる
往復型圧縮機に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a reciprocating compressor used in a cooling system for a refrigerator, a cooling case, etc.
従来の技術
近年、省エネの観点から圧縮機の効率向上の要求が高ま
っている。以下従来例を第5図、第6図に従い説明する
。BACKGROUND OF THE INVENTION In recent years, there has been an increasing demand for improving the efficiency of compressors from the viewpoint of energy conservation. A conventional example will be explained below with reference to FIGS. 5 and 6.
第6図において、1はモータ3と圧縮機構からなるコン
プレッサーユニットである。6は前記圧縮機構4を構成

。In FIG. 6, 1 is a compressor unit consisting of a motor 3 and a compression mechanism. Reference numeral 6 denotes a cylinder constituting the compression mechanism 4, which includes a piston 6 reciprocated by the motor 3, a suction reed valve seat 7a having a suction reed valve 7 with lift processing (bending processing), and a valve having a discharge reed valve 8. Each of them is equipped with a plate 9.

ダー6内のガスが吐出リード弁8を押し上げ吐出室に流
nる。吸入工程では吐出リード弁8が閉じ、吸入リード
弁7が開き低圧ガスがシリンダ5内に吸い込ま扛る。In the above configuration, the gas in the cylinder 5 is compressed by the movement of the piston 6, and in the compression stroke, the gas in the cylinder 6 pushes up the discharge reed valve 8 and flows into the discharge chamber. In the suction process, the discharge reed valve 8 is closed, the suction reed valve 7 is opened, and low pressure gas is sucked into the cylinder 5.
発明が解決しようとする問題点
このような構成において吸入行程が開始し、ピストン6
が図中右側へ移動を始めても吸入リード弁7は油の粘性
力でバルブプレート9に密着しているため、かなりの差
圧がつくまで開かない。このため吸入行程中、実際吸入
リード弁7が開いている時間は短かく、シリンダ5のガ
ス充填効率が悪いため性能が落ちる欠点を有していた。Problem to be Solved by the Invention In this configuration, the suction stroke starts and the piston 6
Even if the valve starts to move to the right in the figure, the suction reed valve 7 remains in close contact with the valve plate 9 due to the viscous force of the oil, so it will not open until a considerable pressure difference is built up. Therefore, during the suction stroke, the time during which the suction reed valve 7 is actually open is short, and the gas filling efficiency of the cylinder 5 is poor, resulting in a reduction in performance.
本発明は上記欠点に鑑み、応答性にすぐれた弁機構を備
えた往復型圧縮機を提供することを目的とする。SUMMARY OF THE INVENTION In view of the above drawbacks, it is an object of the present invention to provide a reciprocating compressor equipped with a valve mechanism with excellent responsiveness.

。Means for Solving the Problems In order to solve these problems, the valve mechanism of the reciprocating compressor of the present invention has a suction reed valve on the cylinder side, a discharge reed valve on the opposite cylinder side, and one end is connected to the suction reed valve on the side opposite to the cylinder. It consists of a valve plate provided with a through hole that opens at the position of the reed valve and the other end opens at the position of the discharge reed valve.

27の固定用貫通孔である。21 is a compressor unit consisting of a motor 23 and a compression mechanism 24. Reference numeral 25 denotes a cylinder constituting the compression mechanism 24, and includes a piston 26 that is reciprocated by the motor 23, a suction reed valve 27, a discharge reed valve 28, and a valve plate 29. 32 is a stopper for regulating the movement of the discharge reed valve 28, 33 is a spring for fixing the stopper 32, and 34 and 35 are keepers and pins. 36 is a through hole provided in the valve plate 29, one end of which opens opposite the suction reed valve 27;
The other end is open facing the discharge reed valve 28. 43
37 and 40 are the valve plate 29 and the suction through hole of the suction reed valve 27; 38 and 41 are the discharge through holes;
Similarly, 9.42 is a through hole for fixing the valve plate 29 and the suction reed valve 27.
上記構成において動作を説明するとピストン26により
圧縮さ扛たガスは吐出リード弁28を介して吐出室37
に吐出さ扛る。この際吐出リード28は開いているため
、貫通孔36は吐出室37と連通するため同じ圧力とな
る。次に吸入行程にはいると吐出リード升28が閉じ、
シリンダー25内圧力が貫通孔36内の圧力より低くな
ると、貫通孔36内に溜まっているガスの圧力により吸
入リード弁27の弁部43は半開き状態となり外部圧力
よりシリンダー26内圧が低くなるとただちに吸入リー
ド弁27の弁部43は開き吸入が開始さnる。To explain the operation in the above configuration, the gas compressed by the piston 26 is passed through the discharge reed valve 28 to the discharge chamber 37.
Spit out and pick up. At this time, since the discharge lead 28 is open, the through hole 36 communicates with the discharge chamber 37, so that the pressure is the same. Next, when entering the suction stroke, the discharge lead box 28 closes,
When the internal pressure of the cylinder 25 becomes lower than the pressure inside the through hole 36, the valve part 43 of the suction reed valve 27 becomes a half-open state due to the pressure of the gas accumulated inside the through hole 36, and as soon as the internal pressure of the cylinder 26 becomes lower than the external pressure, suction is started. The valve portion 43 of the reed valve 27 opens and suction begins.
したがって従来リフト加工のみでは不充分であった吸入
リード弁27を押し開ける力が生ま扛吸入ガスの充填効
率を向上させる効果が得ら扛る。Therefore, a force is generated to push open the suction reed valve 27, which was insufficient in the conventional lift process alone, and the effect of improving the filling efficiency of suction gas cannot be obtained.
発明の効果
以上のように本発明は一端が吸入リード弁の位置に開口

する0Effects of the Invention As described above, the present invention uses a valve plate 1 having a through hole with one end opening at the suction reed valve position and the other end opening at the discharge reed valve position. The suction reed valve is forcibly opened by the pressure of high-pressure gas, which has the effect of improving gas filling efficiency during suction.
