【考案の詳細な説明】
本考案は圧縮機の弁板とヘッドとの間に挟持されて冷却
回路内に封入されている流体の漏れを防止するガスケッ
トの改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a gasket that is sandwiched between a valve plate and a head of a compressor to prevent leakage of fluid sealed in a cooling circuit.
従来使用されているガスケットは第１図に示すようにヘ
ッドの内部形状と同一に形成されており、吐出室と吸入
室のシール部幅はヘッドの吸入室と吐出室を圧力的に分
離する隔壁の幅と等しくなっていた。Conventionally used gaskets are formed to have the same internal shape as the head, as shown in Figure 1, and the width of the seal between the discharge and suction chambers is the same as the partition that pressure-wise separates the suction and discharge chambers of the head. was equal to the width of
このため圧縮機に異常現象が生じ、吐出室が異常高圧と
なった場合には弁板あるいはヘッドに変形が生ずるとと
もに弁板とヘッドとの間に介在させているガスケットも
高圧のため、吐出室から吸入室側に押し出されて破損す
る危険が生じていた。For this reason, if an abnormal phenomenon occurs in the compressor and the discharge chamber becomes abnormally high pressure, the valve plate or head will be deformed, and the gasket interposed between the valve plate and the head will also be under high pressure, causing the discharge chamber to become abnormally high pressure. There was a risk that the product would be pushed out into the suction chamber and damaged.
本考案はこのような欠陥を除去するためガスケットの外
周側に形成している吸入室空間を弁板に穿設されている
吸入孔と対応する個所に吸入孔と同一径の小孔に形成し
てガスケットの切り抜き量を少なくすることにより吐出
内の異常高圧によるガスケットの破損を防止することを
目的とするものである。In order to eliminate such defects, the present invention creates a small hole with the same diameter as the suction hole in the suction chamber space formed on the outer circumferential side of the gasket at a location corresponding to the suction hole drilled in the valve plate. The purpose of this is to prevent damage to the gasket due to abnormally high pressure within the discharge by reducing the amount of gasket cutout.
以下本考案を実施例を示す図面によって説明する。The present invention will be explained below with reference to drawings showing embodiments.
１はガスケットで、吸入孔２ａおよび吐出孔２ｂを穿設
した弁板２と、吸入室３ａおよび吐出室３ｂを形成した
ヘッド３との間に挟持されている。A gasket 1 is held between a valve plate 2 having a suction hole 2a and a discharge hole 2b, and a head 3 having a suction chamber 3a and a discharge chamber 3b.
４は該ガスケットの中央部に穿設された吐出室空間で、
ヘッド３の吸入室３ａと吐出室３ｂを圧力的に分離して
いる隔壁９と同一形状をなしている。4 is a discharge chamber space bored in the center of the gasket;
It has the same shape as the partition wall 9 that pressure-wise separates the suction chamber 3a and discharge chamber 3b of the head 3.
また５は吐出室空間４の外周上に穿設された吸入小孔で
、該吸入小孔５は弁板２上に穿設されている吸入孔２ａ
と対応する個所に形成され、吸入孔２ａと同一の径を有
するものである。Reference numeral 5 denotes a small suction hole bored on the outer periphery of the discharge chamber space 4, and the small suction hole 5 is a suction hole 2a formed on the valve plate 2.
It is formed at a location corresponding to the suction hole 2a and has the same diameter as the suction hole 2a.
６はヘッド３をガスケット１および弁板２とともにケー
シング７に固定するためのボルト８を貫通させるボルト
孔である。Numeral 6 is a bolt hole through which a bolt 8 for fixing the head 3 together with the gasket 1 and the valve plate 2 to the casing 7 is passed.
ガスケット１を弁板２とヘッド３の間に挟持すると、該
ガスケット１はヘッド３の外周縁と隔壁９によって固着
されるが、吸入室３ａと吐出室３ｂのシール部幅を厚く
したため吐出室３ｂの異常高圧にも耐えられる。When the gasket 1 is sandwiched between the valve plate 2 and the head 3, the gasket 1 is fixed by the outer peripheral edge of the head 3 and the partition wall 9. However, since the width of the seal between the suction chamber 3a and the discharge chamber 3b is made thicker, Can withstand abnormally high pressure.
以上のように本考案はヘッド３の隔壁９と同一に形成し
た吐出室空間４の外周上に弁板２の吸入孔２ａと対応さ
せて同一径とした吸入小孔５を穿設することにより、吸
入室２ａと吐出室２ｂのシール部幅が広くなり、圧縮機
に異常現象が生じて吐出室２ｂが異常高圧となってもガ
スケット１の破損を防止できる効果を有する。As described above, the present invention is achieved by drilling a small suction hole 5 with the same diameter on the outer periphery of the discharge chamber space 4 formed in the same manner as the partition wall 9 of the head 3, so as to correspond to the suction hole 2a of the valve plate 2. The width of the seal between the suction chamber 2a and the discharge chamber 2b is widened, which has the effect of preventing damage to the gasket 1 even if an abnormal phenomenon occurs in the compressor and the discharge chamber 2b becomes abnormally high pressure.
