【発明の詳細な説明】
イ 産業上の利用分野
この発明はピストンとシリンダーの摺動面を液体で充満
して、潤滑と気体のシール作用及び冷却作用を同時に行
なう様にした往復動式気体圧縮機と真空ポンプに関する
。Detailed Description of the Invention A. Field of Industrial Application This invention is a reciprocating gas compression device that fills the sliding surfaces of a piston and cylinder with liquid to simultaneously perform lubrication, gas sealing, and cooling functions. Regarding machines and vacuum pumps.
口 従来の技術
従来の往復動形の気体圧縮機及び真空ポンプノ摺動面の
シールは、ピストンにピストンリングやパツキンを用い
る構造となっているので、摺動には摩擦抵抗が大きく、
摩耗も伴なうので、駆動々力の浪費と、メカニズムの損
耗による短寿命化が避けられない。特にピストンリング
を使用する場合は低速作動では機構上シールドが不完全
になる為全く使用出来ないので２秒速数回以下という作
動の圧縮機や真空ポンプを作ることは難しい。Conventional technology The seals on the sliding surfaces of conventional reciprocating gas compressors and vacuum pumps have a structure that uses piston rings and packings for the piston, so there is a large frictional resistance during sliding.
Since wear also accompanies it, it is unavoidable that driving force is wasted and the life of the mechanism is shortened due to wear and tear. In particular, when piston rings are used, they cannot be used at all due to low-speed operation because the mechanical shield becomes incomplete, so it is difficult to make compressors and vacuum pumps that operate at speeds of several times per second or less.
ハ 問題点を解決する為の手段
この発明を空気圧縮として実施した場合の例を図面にも
とづいて説明すると次の様になる。C. Means for Solving the Problems An example of implementing this invention as an air compressor will be explained below based on the drawings.

と共に上下に往復運動をし、オイルタンク１１のオイル
をシリンダーカバー１２に送油する。The piston moves up and down by the crankshaft 2. A crankshaft 2 driven by a motor 20 is connected to a connecting rod 3 and converts its circular motion into a swinging motion of a lever 4. A roller 4α at the tip of the lever 4 transmits the vibration to the piston rod 5 and converts the swinging motion of the piston 5 into an up and down motion of the piston 1. As the piston 1 moves up and down, air passes through the purifier 8, opens the intake valve 6, is sucked into the cylinder 9, is compressed, and is discharged from the discharge valve 7. The tip of a plunger 10α of an oil pump is attached to the lever 4, and it reciprocates up and down with a rocking motion to send oil from an oil tank 11 to a cylinder cover 12.
この作動はピストン１が下降する吸入行程の時、オイル

量より多いと、常時油溝１０Ｌはオイルで満されている
ことになり、過剰に噴出されたオイルはピストン１が上
死点に来た時噴出弁７の方向に流れ、圧縮空気と共に吐
出される。During this operation, during the suction stroke when the piston 1 descends, the oil pump 10 discharges oil, and as shown in FIG. erupts towards. At this time, oil accumulates in the oil groove 1α of the piston 1, but the amount of oil that is ejected from the piston 1
If the amount is greater than the amount leaking downward from the sliding surface between the cylinder wall 9α and the oil groove 10L, the oil groove 10L is always filled with oil, and the excess oil will cause the piston 1 to reach the top dead center. When it comes, it flows in the direction of the jet valve 7 and is discharged together with the compressed air.

漏洩したオイルも。Oil is separated from the discharged air in a gas-liquid separation chamber 14,
The oil is sent out from the discharge port 15, but the oil is sent out from the float valve 16.
Open it and return to oil tank 11 again. Also, oil leaked from the sliding surface.
戻し口１７よりオイルタンク１１に戻る。It returns to the oil tank 11 through the return port 17.
二 作 用
ピストン１とシリンダー壁９ａとの摺動面ヲ通って下方
に漏れるオイルの量より多くの量を噴出口Ｂより供給す

気が通過すべき摺動面の間隙はオイルで完全に遮断され
る。2. Function If a larger amount of oil is supplied from the spout B than the amount of oil that leaks downward through the sliding surface between the piston 1 and the cylinder wall 9a, oil will always remain in the oil groove 1α, and air will be The gap between the sliding surfaces through which the oil must pass is completely blocked by oil.
これは摺動面の様な微細な間隙を流体が流れる場合、気
体より粘度がはるかに大きい液体は流動抵抗が大きい為

トン上面１ｂを冷却し、吐出時に過剰オイルも圧縮空気
と一緒に吐出されるので、圧縮過程が断熱圧縮より等温
圧縮に近い作動になる。This is a method that takes advantage of the fact that when a fluid flows through minute gaps such as sliding surfaces, a liquid with a much higher viscosity than a gas has a large flow resistance and cannot pass through it as quickly as a gas. In this case, the oil cools the cylinder inner wall 9α and the piston upper surface 1b, and excess oil is also discharged together with the compressed air at the time of discharge, so that the compression process is closer to isothermal compression than adiabatic compression.

れ省エネルギー効果が得られる。E. Effects of the Invention Since the sliding parts are sealed with liquid as described above, the frictional resistance of piston rings, packings, etc. is eliminated.9 Power loss associated with mechanical friction is significantly reduced, and the wear and tear of frictional parts is reduced. The problem of short lifetime of the mechanism is also solved. As the compression approaches isothermal compression, the compression work is reduced, resulting in an energy-saving effect.
又摺動部が液膜による間接々触となるので。Also, the sliding parts come into contact with each other due to the liquid film.
使用する液体にはオイル以外に水の様な液体も使うこと
が出来、油分の全く含まれない気体の圧縮も可能になる
ので、従来の圧縮機では使用出来なかった分野にも広く
使えるという効果がある。In addition to oil, liquids such as water can be used as liquids, and it is also possible to compress gas that does not contain any oil, so it can be used in a wide range of fields where conventional compressors cannot be used. There is.
更に機械の構造を第３図の様にすると、液体シールドの
原理はそのま＼真空ポンプに応用出来る。Furthermore, if the structure of the machine is changed to the one shown in Figure 3, the principle of liquid shielding can be directly applied to a vacuum pump.

The air in the vacuum chamber 25 is sucked out by the action of. In this case, the oil for the shield is supplied by the oil pump 12 from the oil injection port 13 provided in the cylinder cover 12, as in the case of FIG.

利用したこの発明の原理は圧縮機だけではなく、真空ポ
ンプの分野にも広く応用出来る。Looking at the gas pressure, the inside of the cylinder 26 becomes negative pressure compared to the outside, so the oil leaks downward while shielding the sliding surface of the piston 22, and the excess oil flows from the overflow port 27 through the float valve 16. Return to oil tank 11. The oil shielding effect and circulation in this case are the same as in the case of a compressor. Therefore, the principle of the present invention, which utilizes the characteristic that the flow resistance of liquid is greater than that of gas, can be widely applied not only to compressors but also to the field of vacuum pumps.
