【０００１】
【発明の属する技術分野】
本発明は手動と空気圧駆動とを両方利用可能なオイル吸引装置に係り、特に空気圧駆動吸気手段のエヤ吸入路では制御装置が設けており、吸い込んだオイルが満タンになったときに、自動的にエヤ吸入路を閉鎖できるオイル吸引装置に関する。
【０００２】
【従来の技術】
図７と図８を参照する。これらは従来の手動と空気圧駆動とを両方利用できるオイル吸引装置であり、中空なケース８１を有し、前記ケース８１のなかには貯油空間８２を有し、前記貯油空間８２のなかには浮き板８３が設けられており、且つ前記ケース８１の上には上蓋８４が設けられており、前記上蓋８４には、手動吸気手段７と、空気圧駆動吸気手段６と、吸油管８５とが設けられている。
【０００３】
前記空気圧駆動吸気手段６はエヤ源に接続したエヤ吸入路６１を有し、前記エヤ吸入路６１の端末には排気口６２を有し、且つ前記エヤ吸入路６１は前記貯油空間８２と連通した吸気路６３を有し、前記吸気路６３のなかには間隔を置いた複数の塞げ片６４が設けており、且つ前記吸気路６３の底端には座体６５が設けられており、前記座体６５の内部にはスチール玉６６が設けられている。前記座体６５の底部には貫通孔６５１が設けられており、前記座体６５の底部とスチール玉６６との間にはシールリング６７が設けられており、平常時には、前記スチール玉６６は自重で落下し前記貫通孔６５１を閉鎖しする。そうすると、前記空気圧駆動吸気手段６は前記貯油空間８２と連通しないので、手動吸気手段７よりエヤを吸引してオイルを吸い込むことができる。
【０００４】
前記手動吸気手段７は鉛直に立つ吸油筒７１を有し、前記吸油筒７１のなかにはピストン７２が設けられている。前記ピストン７２のピストンロッド７３は上蓋８４を挿通して外に伸び、前記ピストンロッド７３の上端には使用者の操作のためのハンドル７４が設けている。前記上蓋８４には、貯油空間８２と吸油筒７１とに連通したエヤ吸入路（図示せず）を有し、且つ前記エヤ吸入路の開閉は浮きボール７５に制御され、貯油空間８２内の吸い込んだオイルが増加すると、オイルが前記浮きボール７５を上へ押しエヤ吸入路を閉鎖して吸油筒７１へのオイルの吸込みを停止させる。
【０００５】
上記のような構成において、手動吸気手段７は、貯油空間８２内の吸い込んだオイルが満タンした場合にエヤ吸入路を閉鎖するための浮きボール７５を有するが、空気圧駆動吸気手段６は上記のような機構がない。すなわち、前記空気圧駆動吸気手段６よりオイルを吸い込む場合には、貯油空間８２内のオイルレベルが座体６５の高さに至ると、オイルが座体６５の貫通孔６５１から吸気路内に吸われて排気口６２から噴出する問題があった。
【０００６】
【発明が解決しようとする課題】
本発明の主な目的は、制御装置において、スリーブに嵌めている自在ブロックが下へ伸びたロッドを有し、貯油空間内の吸い込んだオイルが満タンした場合に浮き板が上昇され前記ロッドを押し、それに従って前記ロッドと結合した自在ブロックの上のシールパッキンが前記座体の貫通孔を閉鎖するため、貯油空間内のオイルが外部に洩れない手動と空気圧駆動とを両方利用可能なオイル吸引装置を提供する。
【０００７】
本発明の次な目的は、自在ブロックの上のシールパッキンが座体の貫通孔を閉鎖するとともに、ピンが座体内の塞げ体を押し除けるため、シールパッキンとシリコンリングとの間にある空間が吸気路と連通し、前記制御装置がロックされない手動と空気圧駆動とを両方利用可能なオイル吸引装置を提供する。
【０００８】
本発明のもう一つの目的は、自在ブロックから伸びたロッドのなかにウェートが嵌められているため、空気圧駆動吸気手段よりエヤを吸っている際に、自在ブロックが上へ吸引されて座体の貫通孔を閉鎖することがない手動と空気圧駆動とを両方利用可能なオイル吸引装置を提供する。
【０００９】
【課題を解決するための手段】
上記目的を達成するためになされた本願では、中空なケースを有し、前記ケースのなかには貯油空間を有し、前記貯油空間のなかには浮き板が設けており、前記ケースの上には上蓋が設けてられており、
前記上蓋には、手動吸気手段と、空気圧駆動吸気手段と、吸油管とが設けられ、前記空気圧駆動吸気手段はエヤ吸入路を有し、前記エヤ吸入路は前記貯油空間と連通した開口を有し、前記エヤ吸入路のなかには複数の塞げ片が距離を置いて設けられており、前記空気圧駆動吸気手段は制御装置が設けられており、前記制御装置が開状態である場合、前記空気圧駆動吸気手段が前記貯油空間の内部のエヤを吸い出してオイルを吸入するように前記貯油空間が前記空気圧駆動吸気手段と連通した状態であり、前記制御装置が閉状態である場合、前記貯油空間が前記空気圧駆動吸気手段と連通しない状態であり、
手動吸気手段にてオイルを吸入可能な手動と空気圧駆動とを両方利用可能なオイル吸引装置において、
前記制御装置は、座体と、塞げ体と、スリーブと、自在ブロックとを有し、
前記座体は、前記エヤ吸入路の開口で設けられ、前記座体と前記エヤ吸入路との間には移動空間が形成され、前記座体のエヤ吸入路から遠ざかった一端には前記移動空間まで貫通した貫通孔を有し、
前記塞げ体は、前記移動空間の内部に設けられ、自重により常時に前記貫通孔を閉鎖し、
前記スリーブは、前記座体の前記空気圧駆動吸気手段と結合した一端の反対側に結合され、前記スリーブには多数の吸気孔を有し、前記スリーブの前記上蓋から遠ざかった一端には孔を有し、
前記自在ブロックは、前記スリーブのなかに挿入され、前記自在ブロックから前記スリーブの孔を挿通したロッドが伸びており、前記自在ブロックの前記座体に近接した端面にはシールパッキンが設けられており、前記端面には前記座体の貫通孔と対応したピンが設けられており、エヤを流通するように、前記ピンの外徑は対応した前記貫通孔の内径より小さく、
前記自在ブロックのロッドが浮き板に押されて上へ移動しシールパッキンが前記貫通孔を閉鎖した場合、前記ピンにより前記塞げ体を押し除け可能であることを特徴とする。
【００１０】
【発明の実施の形態】
以下、本発明の実施の形態を示す実施例を図面に基づいて説明する。
図１から図４に示すように、本発明の実施例による手動と空気圧駆動とを両方利用可能なオイル吸引装置は、中空なケース１を有し、前記ケース１のなかには一貯油空間１１を有し、前記貯油空間１１のなかには浮き板１２が設けられている。前記ケース１の上には上蓋１３が設けられており、前記上蓋１３には、手動吸気手段２と、空気圧駆動吸気手段３と、吸油管１４とが設けられている。
【００１１】
前記手動吸気手段２は鉛直に立つ吸油筒２１を有し、前記吸油筒２１のなかにはピストン２２が設けられており、前記ピストン２２のピストンロッド２３は上蓋１３を挿通して外に伸び、前記ピストンロッド２３の上端には使用者の操作のためのハンドル２４が設けている。前記上蓋１３には、貯油空間１１と吸油筒２１とに連通したエヤ吸入路１３１を有し、且つ前記エヤ吸入路１３１の開閉は浮きボール２５に制御され、貯油空間１１内の吸い込んだオイルが増加すると、オイルが前記浮きボール２５を上へ押しエヤ吸入路１３１を閉鎖して吸油筒２１へのオイルの吸込みを停止させる。
【００１２】
空気圧駆動吸気手段３はエヤ源に接続したジョイント３１を有し、前記ジョイント３１は主流路３２と連通し、前記主流路３２の他端が排気口３３と接続している。前記主流路３２の中段は吸気路３４と連通し、前記吸気路３４が前記貯油空間１１まで貫通した開口３４１を有し、前記吸気路３４のなかには間隔を置いた複数の塞げ片３４２が設けており、且つ前記吸気路３４の開口３４１には制御装置４が接続している。
【００１３】
前記制御装置４は、前記吸気路３４の開口３４１で設けた座体４１を有し、前記座体４１と前記吸気路３４との間には移動空間４２が形成しており、且つ前記座体４１の吸気路３４から遠ざかった一端には前記移動空間４２まで貫通した貫通孔４１１を有している。前記座体４１の前記貫通孔４１１の周縁には塞げ面４１２が形成されている。前記移動空間４２のなかには塞げ体が設けられている。本実施例では、前記塞げ体はスチール玉４３であり、且つ前記座体４１において、前記塞げ面４１２と前記スチール玉４３の間には中空なシリコンリング４４が設けられており、前記シリコンリング４４により貫通孔４１１と移動空間４２が連通状態になり、且つ前記シリコンリング４４の前記スチール玉４３と対応した処では円錐状の窪み部４４１が形成されている。前記スチール玉４３の外徑は前記窪み部４４１の最小徑より大きくにし、そうすると、平常時に、前記スチール玉４３が自重で窪み部４４１を塞げて貫通孔４１１を閉鎖する。この場合には、前記空気圧駆動吸気手段３は前記貯油空間１１と連通しないので、手動吸気手段２よりエヤを吸引してオイルを吸い込むことができる。
【００１４】
前記座体４１の吸気路３４から遠ざかった一端はスリーブ４５に嵌められており、前記スリーブ４５には複数の吸気孔４５１が開けており、且つ前記スリーブ４５の前記座体４１から遠ざかった一端には孔４５２を有する。
【００１５】
前記スリーブ４５のなかには自在ブロック４６が設けられており、前記自在ブロック４６から前記スリーブ４５の孔４５２を挿通したロッド４６１が伸びており、且つ前記ロッド４６１にはウェート４６２が嵌められている。前記自在ブロック４６の前記座体４１に隣接した端面４６３では、座体４１の貫通孔４１１に対応したピン４６４が設けられており、エヤを流通するように、前記ピン４６４の外徑は対応した前記貫通孔４１１の内径より小さく、前記ピン４６４の前記端面４６３に隣接した処にはネック４６５が設けられている。前記ネック４６５に前記シールパッキン４６６が固定され、そうすると、前記自在ブロック４６のロッド４６１が上へ浮き板１２に押されてシールパッキン４６６が前記貫通孔４１１を閉鎖した場合には、前記ピン４６４により前記スチール玉４３を押し除けさせ、前記貫通孔４１１の閉鎖状態を解除することができる。
【００１６】
図５を参照する。空気圧駆動吸気手段３のジョイント３１のスイッチ３１１が開状態にした場合には、圧縮空気がエヤ源から主流道３２に流入し、主流道３２内の圧縮空気が吸気路３４を通過しているときに、吸気路３４が吸引力を発生しスチール玉４３を上へ吸引するが、スチール玉４３が塞げ片３４２に阻まれる。そうすると、貫通孔４１１が吸気路３４と連通するため、貯油空間１１内のエヤは、吸気孔４５１から吸い込まれて貫通孔４１１を経て吸気路３４に入ってから、排気口３３から排出される。
【００１７】
そして、前記自在ブロック４６は、自体が重くてウェート４６２もそれに設けられているため、上へ吸引されることができない。従って、吸気孔４５１と貫通孔４１１との間は開状態に保持する。
【００１８】
貯油空間１１内のエヤが吸われて空気圧が負圧になった後、オイルが吸油管１４から貯油空間１１まで吸い込まれ、オイルレベルの上昇に従って浮き板１２も上へ移動され、貯油空間１１内のオイルレベルが一定の高さになると、自在ブロック４６のロッド４６１は前記浮き板１２に押されて上へ移動しつつ、シールパッキン４６６が座体４１に当接し貫通孔４１１を閉鎖すると自在ブロック４６も止まる（図６に示す）。そうすると、オイルが吸気路３４から吸い出される問題はなくない。
【００１９】
特に注意すべきのは、自在ブロック４６が上へ移動されてシールパッキン４６６が座体４１に当接し貫通孔４１１を閉鎖するとともに、自在ブロック４６のピン４６４は、貫通孔４１１を通過してジョイント３１のスイッチ３１１を閉にした後に落下したスチール玉４３を上へ上げる。そうすると、スチール玉４３は前記窪み部４４１を塞ぐことがなく、シールパッキン４６６とシリコンリング４４との間にある空間も吸気路３４と連通状態を保持する。
【００２０】
そうしないと、スチール玉４３が落下し窪み部４４１を塞がれば、シールパッキン４６６とシリコンリング４４との間にある空間は真空状態になって、貯油空間１１内のオイルが排出しても自在ブロック４６が落下できなくなり、ひいては制御装置４がロックされる。制御装置４がロックされれば、空気圧駆動吸気手段３は作動できない。
【００２１】
本実施例には次のような効果がある。
（イ）制御装置４において、スリーブ４５に嵌めている自在ブロック４６が下へ伸びたロッド４６１を有し、貯油空間１１内の吸い込んだオイルが満タンした場合に浮き板１２が上昇され前記ロッド４６１を押し、それに従って前記ロッド４６１と結合した自在ブロック４６の上のシールパッキン４６６が前記座体４１の貫通孔４１１を閉鎖する。そのため、貯油空間１１内のオイルが外部に洩れない。
【００２２】
（ロ）前記自在ブロック４６のロッド４６１が浮き板１２に押されて上へ移動し、シールパッキン４６６が前記貫通孔４１１を閉鎖するとともに、前記ピン４６４が座体４１内のスチール玉４３を押し除けて、シールパッキン４６６とシリコンリング４４との間にある空間が吸気路３４と連通する。そのため、前記制御装置がロックされたことを回避することができる。
【００２３】
（ハ）前記自在ブロック４６から伸びたロッド４６１のなかにウェート４６２が嵌められているため、空気圧駆動吸気手段３よりエヤを吸っている際に、自在ブロック４６が上へ吸引されて座体４１の貫通孔４１１を閉鎖することを回避することができる。

As a result, the through-hole 411 and the moving space 42 are in communication with each other, and a conical depression 441 is formed at a location corresponding to the steel ball 43 of the silicon ring 44. The outer rim of the steel ball 43 is made larger than the minimum ridge of the dent portion 441. Then, the steel ball 43 closes the dent portion 441 with its own weight and closes the through hole 411 in normal times. In this case, since the pneumatic drive intake means 3 does not communicate with the oil storage space 11, the oil can be sucked by sucking air from the manual intake means 2.
[0014]
One end of the seat body 41 away from the intake passage 34 is fitted into a sleeve 45, a plurality of intake holes 451 are formed in the sleeve 45, and one end of the sleeve 45 away from the seat body 41. Has a hole 452.
[0015]
A free block 46 is provided in the sleeve 45, and a rod 461 inserted through the hole 452 of the sleeve 45 extends from the free block 46, and a weight 462 is fitted on the rod 461. A pin 464 corresponding to the through hole 411 of the seat body 41 is provided on the end surface 463 adjacent to the seat body 41 of the universal block 46, and the outer flange of the pin 464 corresponds to distribute the air. A neck 465 is provided at a position smaller than the inner diameter of the through hole 411 and adjacent to the end surface 463 of the pin 464. When the seal packing 466 is fixed to the neck 465, the rod 461 of the free block 46 is pushed upward by the floating plate 12 and the seal packing 466 closes the through hole 411. The steel ball 43 can be pushed away, and the closed state of the through hole 411 can be released.
[0016]
Please refer to FIG. When the switch 311 of the joint 31 of the pneumatic drive intake means 3 is in the open state, compressed air flows into the main flow path 32 from the air source, and the compressed air in the main flow path 32 passes through the intake path 34 In addition, the suction passage 34 generates a suction force to suck the steel ball 43 upward, but the steel ball 43 is blocked and blocked by the piece 342. Then, since the through hole 411 communicates with the intake passage 34, the air in the oil storage space 11 is sucked from the intake hole 451, enters the intake passage 34 through the through hole 411, and then is discharged from the exhaust port 33.
[0017]
And since the said universal block 46 is heavy itself and the weight 462 is also provided in it, it cannot be attracted | sucked upwards. Therefore, the space between the intake hole 451 and the through hole 411 is kept open.
[0018]
After the air in the oil storage space 11 is sucked and the air pressure becomes negative, the oil is sucked from the oil absorption pipe 14 to the oil storage space 11, and the floating plate 12 is also moved upward as the oil level rises. When the oil level reaches a certain level, the rod 461 of the free block 46 is pushed upward by the floating plate 12 and moves upward, while the seal packing 466 abuts against the seat body 41 and closes the through hole 411. 46 also stops (shown in FIG. 6). Then, there is no problem that oil is sucked out from the intake passage 34.
[0019]
Of particular note is that the free block 46 is moved upward so that the seal packing 466 abuts against the seat body 41 and closes the through hole 411, and the pin 464 of the free block 46 passes through the through hole 411 and is joined to The steel ball 43 dropped after the 31 switch 311 is closed is raised. Then, the steel ball 43 does not block the hollow portion 441, and the space between the seal packing 466 and the silicon ring 44 also maintains communication with the intake passage 34.
[0020]
Otherwise, if the steel ball 43 falls and closes the recess 441, the space between the seal packing 466 and the silicon ring 44 is in a vacuum state, and the oil in the oil storage space 11 is discharged. The free block 46 cannot be dropped, and the control device 4 is locked. If the control device 4 is locked, the pneumatically driven intake means 3 cannot operate.
[0021]
This embodiment has the following effects.
(A) In the control device 4, the free block 46 fitted to the sleeve 45 has a rod 461 extending downward, and when the sucked oil in the oil storage space 11 is full, the floating plate 12 is raised and the rod The seal packing 466 on the universal block 46 coupled to the rod 461 is pushed accordingly, and the through hole 411 of the seat body 41 is closed accordingly. Therefore, the oil in the oil storage space 11 cannot leak to the outside.
[0022]
(B) The rod 461 of the universal block 46 is pushed upward by the floating plate 12 and moves upward, the seal packing 466 closes the through hole 411, and the pin 464 pushes the steel ball 43 in the seat body 41. In addition, a space between the seal packing 466 and the silicon ring 44 communicates with the intake passage 34. Therefore, it can be avoided that the control device is locked.
[0023]
(C) Since the weight 462 is fitted in the rod 461 extending from the free block 46, the free block 46 is sucked upward when the air is sucked from the pneumatic drive intake means 3, and the seat 41 It is possible to avoid closing the through-hole 411.
