ステムD1は、吸込み弁部材Ｃのリブ37外周に下端部を嵌合させて棒部36の周囲に起立させたコイルスプリングｓの上端に下端部を当接支持させて、常時コイルスプリングｓにより上方へ付勢された上下端開口の筒状をなし、外周下部に環状の吐出弁座40を突設し、吐出弁座40直上の筒壁部分には一対の吐出弁孔41を穿設している。また、ステムD1の上部には連結筒部材D2を介して装着筒部材D3を連結している。連結筒部材D2は下部をステムD1の上部に嵌着させ、嵌着部分の下端部は大径筒部50に形成してステムD1との間に環状ピストンD4の一部を嵌合させる環状空間を形成している。 The stem D 1 has a lower end fitted to the outer periphery of the rib 37 of the suction valve member C and is supported by an upper end of a coil spring s which is raised around the rod part 36, and is always moved by the coil spring s. It has a cylindrical shape with an upper and lower opening that is biased upward, and an annular discharge valve seat 40 projects from the lower part of the outer periphery, and a pair of discharge valve holes 41 are formed in the cylindrical wall portion directly above the discharge valve seat 40. ing. Further, the upper portion of the stem D 1 connecting the hollow mounting member D 3 via the coupling tube member D 2. Coupling cylinder member D 2 are then fitted to the bottom to the top of the stem D 1, the lower end portion of the fitting portion fitting part of the annular piston D 4 between the stem D 1 is formed on the large-diameter portion 50 An annular space to be joined is formed.

各吐出弁孔41は対向位置に穿設された縦長なもので、棒部36先端縁のステムD1内最下降位置から、棒部36先端縁のステムD1内最上昇位置までの縦巾を備えている。図１では作動部材Ｄが最上昇位置にあり、即ちステムD1が最上昇位置にあり、この際棒部36の先端縁はステムD1内の最下降位置にある。また、作動部材Ｄを押し下げてステムD1を押し下げれば、棒部36は相対的に上昇してその先端縁は図１の二点鎖線で示す位置にある。従って、各吐出弁孔41は各位置間の縦巾を備えている。 Each discharge valve hole 41 as it vertically bored in the opposite position, the vertical width of the bar portion 36 distal stem D 1 within the lowest position of the edge, up to the uppermost position within the stem D 1 of the rod portion 36 leading edge It has. Actuating member D in FIG. 1 is in the uppermost position, i.e. there stem D 1 is the highest position, the leading end edge of the Cybozu portion 36 is in the lowermost position of the stem D 1. Further, by pushing down the stem D 1 by depressing the actuating member D, the rod portion 36 relatively rises and its leading edge is in the position indicated by the two-dot chain line in FIG. Accordingly, each discharge valve hole 41 has a vertical width between each position.

この場合前記規定内で若干の誤差は当然考慮される。また、それ以上の長さも考慮される。また、吐出弁孔41下端縁の下限位置は突出弁座40を設けた位置よりも少なくとも上方でなくてはならず、上端縁の上限位置は上記要件を満たせばそれ以上延ばすことは可能である。更に、吐出弁孔41は対向位置に一対設けた場合に限らず、前記要件を満たせば１カ所であっても３個所以上であっても良い。但しステムの耐久性と、液の流動効率との配分を考慮すれば、対向位置に一対設けた場合がより好ましく採用できる。また、図示例では吐出弁孔41の上端縁を外方へ傾斜上昇する如く構成しているが、内方へ傾斜上昇する如く構成することで、棒部36上方への液の流動性をより円滑に行える。   In this case, a slight error is naturally taken into consideration within the above-mentioned definition. In addition, longer lengths are also considered. Further, the lower limit position of the lower end edge of the discharge valve hole 41 must be at least above the position where the protruding valve seat 40 is provided, and the upper limit position of the upper end edge can be extended further if the above requirements are satisfied. . Furthermore, the discharge valve holes 41 are not limited to a pair provided at the opposed positions, and may be one place or three places or more as long as the above requirements are satisfied. However, in consideration of the distribution between the durability of the stem and the flow efficiency of the liquid, the case where a pair is provided at the opposing position can be more preferably employed. In the illustrated example, the upper end edge of the discharge valve hole 41 is configured to be inclined and raised outward. However, by configuring the upper edge of the discharge valve hole 41 to be inclined and raised inward, the fluidity of the liquid above the rod portion 36 is further improved. It can be done smoothly.

更に、押下ヘッドD5内には梃部材D7を設けている。梃部材D7は、開閉弁部材D6後端部に上端を連係させるとともに、下端部を装着筒部材D3の頂板部61上面に当接係止させており、また、装着筒部材D3に対する押下ヘッドD5の押し下げ時に開閉弁部材D6を後方へ引き出す如く揺動可能に枢着している。 Further, there is provided a lever member D 7 is the pressing head D 5. Lever member D 7, together to coordinate the upper end to the opening and closing valve member D 6 rear portion, and a lower end abutting engagement thereby locked to the top panel 61 top surface of the mounting tubular member D 3, also hollow mounting member D 3 It is swingably pivoted as draw-off valve member D 6 rearward when pushed down the pressing head D 5 against.

図示例に於ける梃部材D7は、上端部を開閉弁部材D6の後端部に連係した垂直板部90下端部より前方へ下る二股の傾斜板部91を延設するとともに、各傾斜板部91の下端部を摺動筒62両側の頂板部61上面に当接係止させている。梃部材D7と開閉弁部材D6との連係は、垂直板部90の上端部中央に設けた切欠部に開閉弁部材D6の上記環状凹部を嵌合させている。 In lever member D 7 in the illustrated example, as well as extend the bifurcated inclined plate portion 91 down the upper portion to the front of the vertical plate portion 90 lower end which is linked to the rear end of the opening and closing valve member D 6, the inclined The lower end portion of the plate portion 91 is brought into contact with and locked to the upper surface of the top plate portion 61 on both sides of the sliding cylinder 62. Integration with lever member D 7 and the opening and closing valve member D 6 has the annular recess of the opening and closing valve member D 6 is fitted into the notch provided on the upper end center of the vertical plate portion 90.

また、屈折部分両側に突設した枢着軸を、それぞれ両側の軸受に回動可能に嵌合させている。そして、第２コイルスプリングs1により前方付勢された開閉弁部材D6により垂直板部90上部の連係部分を常時前方へ付勢させており、押下ヘッドD5の押し下げにより、装着筒部材D3の頂板部61が傾斜板部91を押し上げて梃部材D7を回動させ、第２コイルスプリングs1の前方付勢力に抗して開閉弁部材D6を後方へ引き出す如く構成している。 Further, pivot shafts provided on both sides of the refracting portion are fitted to the bearings on both sides so as to be rotatable. Then, and to bias the linkage portion of the vertical plate portion 90 top to always forward by the second on-off valve member D 6 which is forward biased by the coil spring s 1, by depressing the pressing head D 5, the hollow mounting member D The top plate portion 61 of 3 pushes up the inclined plate portion 91 to rotate the collar member D 7 and pulls the on-off valve member D 6 backward against the forward biasing force of the second coil spring s 1 . .

この様な押下ヘッドD5は、ステムD1に対する押下ヘッドD5の押下抗力がステム自体の押下抗力より小になる様に構成している。この様に構成するために、基本的には装着するポンプのステムを上方付勢させるための弾性材よりも、開閉弁部材D6を前方付勢させるための弾性材の弾発力を小さく選択すれば良く、その他摺動筒とシリンダとの摩擦力，梃部材の揺動時の摩擦力等を考慮してこれらを選択すれば良い。 Such pressing head D 5 is pressed drag pressing head D 5 relative to the stem D 1 is configured so as to be a smaller than pressing force of the stem itself. To configure in this way, than the elastic material to essentially be upward urge the stem of the pump mounting small select elastic force of the elastic member for the opening and closing valve member D 6 are forward forcing These may be selected in consideration of the frictional force between the sliding cylinder and the cylinder, the frictional force when the saddle member is swung, and the like.

押下ヘッドD5の外周下部には前記案内筒12の各案内凹溝13に対して上下動可能に嵌合する一対の突部82を突設している。各突部82が案内凹溝13位置にある場合には押下ヘッドD5の押し込みが可能であり、牽いては作動部材Ｄの上下動が可能である。一方、その状態から押下ヘッドD5を回動させて係止用凹溝14上に位置させれば、押下ヘッドD5の押し下げを防止できる。 The outer peripheral lower portion of the pressing head D 5 are projected a pair of projections 82 which vertically movably fitted relative to the guide grooves 13 of the guide cylinder 12. If the projections 82 are in the guide grooves 13 positions are possible depression of the pressing head D 5, is drawn are possible vertical movement of the actuating member D. On the other hand, if the position of the pressing head D 5 from this state by turning on the locking groove 14 can be prevented depressed depression head D 5.

上記の如く構成したポンプ１は、図１の状態から押下ヘッドD5を押し下げると、最初ステムD1は下がらず、装着筒部材D3に対して押下ヘッドD5が下降する。この際、梃部材D7の下端部が装着筒部材D3の頂板部61上面に押し上げられて枢着軸を中心に回動し、その上端部が後方へ回動して開閉弁部材D6を第２コイルスプリングs1の弾発力に抗して後方へ移行させ、吐出口81が開く。 Pump 1 configured as described above, depressing the pressing head D 5 from the state of FIG. 1, the first stem D 1 is not lowered, the pressing head D 5 descends relative to the mounting cylinder member D 3. In this case, the lever member lower end of the D 7 is pushed up to the top panel 61 top surface of the mounting tubular member D 3 rotates about the pivot axis, the opening and closing valve member D to pivot the upper end to the rear 6 Is moved backward against the elastic force of the second coil spring s 1 , and the discharge port 81 is opened.

次いでステムD1が下降し、該ステムD1の下降により環状ピストンD4がステムD1に対して相対上昇して吐出弁73が開き、シリンダＢ内の加圧液が吐出弁孔41を介してステムD1内を通り、摺動筒62内導入され、次いでシリンダ部80内、弁室Ｒ内を通り、吐出口81より吐出される。この際吸込み弁部材Ｃの棒部36はステムD1内にその先端の突出幅を大きく浸入してくる。 Next, the stem D 1 is lowered, and when the stem D 1 is lowered, the annular piston D 4 is raised relative to the stem D 1 to open the discharge valve 73, and the pressurized liquid in the cylinder B passes through the discharge valve hole 41. Then, it is introduced into the sliding cylinder 62 through the stem D 1 , and then discharged from the discharge port 81 through the cylinder portion 80 and the valve chamber R. In this case the rod portion 36 of the suction valve member C will come a protruding width of the front end in the stem D 1 greater intruding.

次に押下ヘッドD5の押圧を解除すると、最初ステムD1の上方付勢力により押下ヘッドD5が上昇する。この際、例えば押下ヘッドD5上面を押圧した手が離れないうちにステムD1の上昇が行われ、吐出口81は開いたままの状態で行われる。同時に環状ピストンD4がステムD1に対して相対的に下降して吐出弁73が閉じる。また、同時に棒部36の上端部がステムD1に対して相対的に下降するため、ステムD1内容積が増大する。従って、この時点でステムD1内及び弁室Ｒ内は負圧状態となり、バックサクション機能を発揮する。次いで、手を離す余地ができ、第２コイルスプリングs1の弾発力により開閉弁部材D6が前方へ移行して吐出口81を閉塞し、それに伴い梃部材D7により押下ヘッドD5を装着筒部材D3に対して上方へ押上げ、装着筒部材D3と押下ヘッドD5との関係が元の状態に戻る。 Now releases the pressing of the pressing head D 5, presses the head D 5 rises by the upper biasing force of the first stem D 1. In this case, for example, increase of the stem D 1 While pressing the pressing head D 5 top hand does not leave is performed, the discharge port 81 is carried out in remains open. At the same time, the annular piston D 4 is lowered relative to the stem D 1 and the discharge valve 73 is closed. At the same time since the upper end portion of the rod portion 36 is lowered relative the stem D 1, the stem D 1 internal volume increases. Thus, the stem D 1 and the valve chamber R at this time becomes a negative pressure state, exerts a back suction function. Next, there is room for releasing the hand, and the on / off valve member D 6 moves forward by the elastic force of the second coil spring s 1 to close the discharge port 81, and accordingly, the pressing head D 5 is moved by the collar member D 7. lifting upward relative to the hollow mounting member D 3, the relationship between the mounting tubular member D 3 and pressing head D 5 is returned to its original state.

作動部材Ｄの上昇に伴いシリンダＢ内は負圧化し、それに伴って吸込み弁33が開いてパイプ25を介して容器体100 内の液がシリンダＢ内に導入される。   As the operating member D rises, the inside of the cylinder B becomes negative pressure, and the suction valve 33 is opened accordingly, and the liquid in the container body 100 is introduced into the cylinder B through the pipe 25.
