Description
【考案の詳細な説明】 本考案は圧縮機に関するものである。[Detailed explanation of the idea] The present invention relates to a compressor.
一般に圧縮機はピストンの下降に伴つて、ガス
（例えば空気）が、吸込管接続口、吸込室、吸込
口及び吸込弁と弁座板との隙間を通つて圧縮室に
吸込まれる。また、ピストンが上昇すると吸込弁
が閉じ、圧縮室内のガスが圧縮され、そのガス圧
が吐出室の圧力より高くなると、吐出弁が開き、
圧縮室内のガスは吐出口、吐出弁と弁座板との隙
間を通り吐出室内に拡散され、この室内に滞留し
た後に吐出管接続口を通つて吐出される。 Generally, in a compressor, as a piston moves downward, gas (for example, air) is sucked into a compression chamber through a suction pipe connection port, a suction chamber, a suction port, and a gap between a suction valve and a valve seat plate. Also, when the piston rises, the suction valve closes, compressing the gas in the compression chamber, and when the gas pressure becomes higher than the pressure in the discharge chamber, the discharge valve opens.
The gas in the compression chamber passes through the discharge port, the gap between the discharge valve and the valve seat plate, is diffused into the discharge chamber, and after staying in the chamber is discharged through the discharge pipe connection port.
ところで、周知のように、40℃のガスを大気圧
から10Kgｆ／cm2（Ｇ）まで圧縮すると、吐出ガス
温度は300℃を超える温度となるため、吐出室内
に滞留した高温の吐出ガスにより隔壁が加熱され
る。このため、吸込ガスが吸込室を通過する際に
隔壁を介して吸込ガス温度が上昇されることとな
る。この結果吐出ガス温度は更に上昇することと
なり、こうした悪循環を生じるため、吸込ガス温
度及び吐出ガス温度は非常に高くなる。このため
吸込ガスは熱膨張し、圧縮機の圧縮効率を低下さ
せていた。 By the way, as is well known, when gas at 40℃ is compressed from atmospheric pressure to 10Kgf/cm 2 (G), the temperature of the discharged gas exceeds 300℃. is heated. Therefore, when the suction gas passes through the suction chamber, the temperature of the suction gas is increased through the partition wall. As a result, the discharge gas temperature further increases, creating such a vicious cycle, and the suction gas temperature and discharge gas temperature become extremely high. For this reason, the suction gas thermally expands, reducing the compression efficiency of the compressor.
また、吐出ガス温度が高いため給油式圧縮機の
場合は、吐出室に炭化物が生じて弁等に付着し、
弁の作動に悪影響を及ぼす虞れがあつた。 In addition, in the case of oil-fed compressors, because the discharge gas temperature is high, carbide forms in the discharge chamber and adheres to valves, etc.
There was a risk that the operation of the valve would be adversely affected.
そこで本考案は前述の如き不具合を改善するた

数の突起を設けたものである。 Therefore, the present invention was devised to improve the above-mentioned problems, and its purpose is to cause the suction gas drawn into the suction chamber of the compressor to be heated by the discharge gas and thermally expand. The purpose is to prevent compression efficiency from decreasing. In order to achieve this objective, the present invention has a discharge head that protrudes into the discharge chamber from the inner wall surface of the cylinder head other than the side adjacent to the suction head, and guides the discharge gas discharged from the discharge port to the discharge port. It is provided with a plurality of protrusions.

The discharge valve 15 is at a position where it does not hit even if it opens to the maximum. One short side of the guide wall 17 extends to the vicinity of the discharge pipe connection port 8. As a result, a passage 18 is formed between the guide walls 17 through which the discharged gas flows. In addition, on the central guide wall 17d,

の外表面に伝達される。 In the compressor configured in this way, the discharge valve 15 opens, and the gas in the compression chamber 16 flows through the discharge port 13,
The discharge chamber 1 passes through the gap between the discharge valve 15 and the valve seat plate 4.
1 , this discharge gas is actively led on the one hand to the discharge pipe connection 8 through the passage 18 between the guide walls 17 . On the other hand, the flow tries to flow toward the partition wall 9 side, but is guided by the dividing plate 19 to the upper and lower inner wall surfaces of the discharge chamber 11 through the guide path 20 without directly colliding with the partition wall 9. It is sent to the discharge pipe connection port 8 along the inner wall surface. At this time, the discharged gas comes into contact with the guide wall 17, so the heat of the discharged gas is transferred to the cylinder head 6 via the guide wall 17.
transmitted to the outer surface of the
このように、吐出室１１内の表面積が増大して
吐出室１１内の受熱面積がふえるため、吐出室１
１内の放熱効果が高まる。 In this way, the surface area within the discharge chamber 11 increases and the heat receiving area within the discharge chamber 11 increases, so the discharge chamber 1
The heat dissipation effect within 1 is increased.

い。 Note that the dividing plate 19 may be provided not only at the central guide wall 17d but also at the end of each guide wall 17 as in this embodiment. Conversely, the dividing plate 19 may not be provided, but it is more effective to prevent the temperature from rising on the suction chamber 10 side. In addition, the cylinder head 6
It does not have to have both the suction chamber 10 and the discharge chamber 11 as in this embodiment, but it can also be a separate type in which the suction head part and the discharge head part are located separately, as long as they are located close to each other. good. Further, although the guide wall 17 is provided on the upper wall surface of the discharge chamber 11, it may be provided on any wall surface other than the partition wall 9.
本考案は以上述べた如くであるため次のような

防止できる。 During the discharge process of the compressor, the discharged gas from the discharge port is actively guided to the discharge boat by the plurality of protrusions, so the gas diffused in the discharge chamber can flow smoothly from the discharge port.
The temperature rise in the discharge chamber can be suppressed as much as possible.
In addition, the heat-receiving area in the discharge chamber has increased, and the heat is transferred to the outer surface of the discharge head other than the side adjacent to the suction head, so the rise in temperature of the suction gas can be suppressed to the utmost, and compression efficiency can be improved. Deterioration can be prevented.
