Abstract

<P>PROBLEM TO BE SOLVED: To solve problems in a conventional manual oil pump wherein when the pump is removed from a tank, residual oil in the pump must be intentionally drained because the residual oil remains in an oil suction pipe 3 and at the bottom part of a body 2 even if an oil supply stop valve 1 is opened. <P>SOLUTION: In this manual oil supply pump, a valve element 5a is installed and a return flow passage 9 is formed between a pump body part 2 and the oil suction pipe 3. When the oil supply stop valve 1 is opened, the residual oil thus flows out to the oil levels of a supply can 7a and a reception can 12a without remaining in the pump. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

Detailed Description of the Invention

本発明は、手動式給油ポンプの、給油停止時にポンプ内残油を減らし、取り外し時の垂れこぼれ削減を図る、垂れこぼれの少ない手動式給油ポンプに関するものである。The present invention relates to a manual oil supply pump with less dripping that reduces residual oil in the pump when oiling is stopped and reduces dripping when removed.

従来の手動式給油ポンプは取り外し時に給油停止コックを開放にしても、手動式ポンプ内に残油が残り供給缶及び受給缶から取り外した時、吸油管及び吐出管先端より、垂れこぼれを起こしていた、又ポンプ室およびポンプ胴体内の残油は全て受給缶へ流れ込むため、注意をしていないと受給缶より石油が溢れ出すことがあった。Even if the oil supply stop cock is opened at the time of removal of the conventional manual oil pump, residual oil remains in the manual pump, and when the oil is removed from the supply canister and receiving canister, it spills from the tips of the oil absorption pipe and discharge pipe. Moreover, since all the residual oil in the pump chamber and the pump body flows into the receiving can, oil may overflow from the receiving can unless care is taken.

Problems to be solved by the invention

従来の手動式石油ポンプは、ポンプ停止時の吸油管からの垂れこぼれ、受給缶からの溢れ出しに苦慮している、本発明は給油停止コックを開いた時、吐出管からの流出量を減らし、ポンプ内の残油を殆ど残さない様にできる、又ポンプを取り外す際、吸油管先端及び受給管先端からの垂れこぼれが少なく済むようになされたものである。Conventional manual oil pumps struggle to spill from the oil suction pipe when the pump stops and overflow from the receiving can. The present invention reduces the outflow from the discharge pipe when the oil stop cock is opened. The residual oil in the pump can be hardly left, and when the pump is removed, there is little spillage from the oil absorption pipe tip and the receiving pipe tip.

Means to solve the problem

ポンプ胴体（２）の上部に手動ポンプ（８）を設け、手動ポンプ（８）の上部に給油停止コック（１）を設ける、ポンプ胴体（２）と吸油管（３）の間に弁体（５ａ）と戻し流路（９）を設ける、戻し流路（９）は弁体（５ａ）が閉じた状態でもポンプ胴体（２）と吸油管（３）の間を空気及びポンプ内残油（１３ａ）が流通できる流路である、ポンプ胴体（２）と吐出管（４）の間には吐出逆止弁（６）を設け吐出管（４）からポンプ胴体（２）へ逆流しない弁である、本発明は以上の構成よりなるA manual pump (8) is provided at the top of the pump body (2), and an oil supply stop cock (1) is provided at the top of the manual pump (8). A valve body (2) between the pump body (2) and the oil absorption pipe (3) 5a) and a return flow path (9) are provided. The return flow path (9) is provided with air and residual oil in the pump (3) between the pump body (2) and the oil absorption pipe (3) even when the valve body (5a) is closed. 13a) is a flow path through which a discharge check valve (6) is provided between the pump body (2) and the discharge pipe (4), and does not flow backward from the discharge pipe (4) to the pump body (2). The present invention comprises the above configuration.

以下、本発明の実施の形態を説明する。
手動式給油ポンプにおいて、ポンプ胴体（２）の底辺部と吸油管（３）の間に、弁体（５ａ）と、吐出管（４）よりも孔径が小さい戻し流路（９）を設けることで、給油停止コック（１）を閉じた状態で手動ポンプ（８）に急速な押圧加えると、ポンプ胴体（２）及び手動ポンプ（８）内の空気及び石油（１３ａ）は戻し流路（９）より吸油管（３）へ逆流もするが、戻し流路（９）の孔径を小さくすることにより、大半は吐出逆止弁（６）が開き吐出管（４）へ流出する、スクイブ性のある手動ポンプ（８）から押圧を解除すると吐出逆止弁（６）は閉鎖し、弁体（５ａ）が開き供給石油（７ｂ）は吸油管（３）を通り弁体（５ａ）及び戻し流路（９）を通りポンプ胴体（２）及び手動ポンプ（８）内に流入する、この操作を繰り返す事で供給石油（７ｂ）が吸油管（３）から吐出管（４）へ流れ出す、石油受給缶（１２ａ）に希望量の受給石油（１２ｂ）が流入した時点で、給油停止コック（１）を開くとポンプ胴体（２）及び手動ポンプ（８）内の残油は吐出逆止弁（６）及び戻し流路（９）を通り、吐出管（４）及び吸油管（３）内の残油と共に石油受給缶（１２ａ）及び石油供給缶（７ａ）に流入し、受給石油（１２ｂ）及び供給石油（７ｂ）の油面まで落下して停止する、戻し流路（９）付手動石油ポンプを、給油停止コック（１）を開放状態で、吸油管（３）及び吐出管（４）を石油供給缶（７ａ）及び石油受給缶（１２ａ）より取り外すとき、給油停止コック（１）及び吐出逆止弁（６）及び戻し流路（９）全てが開放になっているので、受給石油（１２ｂ）及び供給石油（７ｂ）の油面と同じ高さにポンプ内残油の高さもなる、よって吐出管（４）及び吸油管（３）先端からの垂れこぼれが殆どなく外せる、ポンプ胴体（２）及び手動ポンプ（８）内の残油は吐出管（４）からと戻し流路（９）からも吸油管（３）を介して石油給油缶（７ａ）へも流出するので石油受給缶（１２ａ）への残油の流れ込みは少なくなる、ポンプ胴体（２）底辺部に残留する残油も戻し流路（９）を設ける事で吸油管（３）へ流出してしまい、手動式給油ポンプを取り外し後の吐出管（４）及び吸油管（３）の先端からの流出は少量で済む。Embodiments of the present invention will be described below.
In a manual oil pump, a valve body (5a) and a return channel (9) having a smaller hole diameter than the discharge pipe (4) are provided between the bottom of the pump body (2) and the oil absorption pipe (3). When the oil supply stop cock (1) is closed and the manual pump (8) is rapidly pressed, the air and oil (13a) in the pump body (2) and the manual pump (8) are returned to the return channel (9). ) Also flows back to the oil absorption pipe (3), but by reducing the hole diameter of the return flow path (9), most of the discharge check valve (6) opens and flows out to the discharge pipe (4). When the pressure is released from a manual pump (8), the discharge check valve (6) is closed, the valve body (5a) is opened, and the supplied oil (7b) passes through the oil absorption pipe (3) and the valve body (5a) and the return flow. By repeating this operation to flow into the pump body (2) and manual pump (8) through the path (9) When the desired amount of received oil (12b) flows into the oil receiving can (12a) when the oil supply (7b) flows from the oil absorption pipe (3) to the discharge pipe (4), the oil supply stop cock (1) is opened. The residual oil in the pump body (2) and the manual pump (8) passes through the discharge check valve (6) and the return flow path (9), and together with the residual oil in the discharge pipe (4) and the oil absorption pipe (3) Supply a manual oil pump with a return flow path (9) that flows into the receiving can (12a) and the oil supply can (7a) and stops by dropping to the oil level of the receiving oil (12b) and the supplying oil (7b). When the oil stop pipe (3) and the discharge pipe (4) are removed from the oil supply can (7a) and the oil supply can (12a) with the stop cock (1) opened, the oil supply stop cock (1) and the discharge check valve (6) and the return flow path (9) are all open, so the received oil (12b) and The pump body (2) and the pump body (2), which has the same height as the oil level of the oil supply (7b), and the height of the residual oil in the pump can be removed. The residual oil in the manual pump (8) flows out from the discharge pipe (4), the return flow path (9) and the oil supply canister (7a) through the oil absorption pipe (3), so that the oil supply canister (12a) Residual oil remaining on the bottom of the pump body (2) also flows out into the oil absorption pipe (3) by providing a return channel (9), and the manual oil pump is removed. A small amount of outflow from the tip of the later discharge pipe (4) and oil absorption pipe (3) is sufficient.

The invention's effect

本発明を使用すると、給油停止コック（１）を解放にした時、戻し流路（９）を設けた事で、手動式給油ポンプ内の残油は殆ど無く、垂れこぼれを削減でき、供給タンク、受給タンクからの手動式給油ポンプの取り外しを容易にできる様にした。 By using the present invention, when the oil supply stop cock (1) is released, the return passage (9) is provided, so that there is almost no residual oil in the manual oil supply pump, and dripping can be reduced. The manual oil pump can be easily removed from the receiving tank.
