- FIG. 10 A perspective view of the plug 10 and the flow rate adjusting screw 11 is shown in FIG.
- the flow rate of the air flowing in from the compressor 1 can be adjusted by adjusting the screwing amount of the flow rate adjusting screw 11 with respect to the flow rate adjusting screw receiver 16, and the compressor 1 as a high pressure fluid supply means can be adjusted.
- the inflowing air can be throttled to a very weak level with the flow adjustment screw 11 of the plug 10.

発明を実施するための最良の形態 BEST MODE FOR CARRYING OUT THE INVENTION
図 2〜図 7は本発明を具体化した第一実施形態としての流体圧力調整器 19及びそ れを利用したリークダウンテスター 20を示している。このリークダウンテスター 20は、 図 3の断面図に示すように、流体としての空気の流路の途中部に介装され、該空気 を上流側から下流側へと中継する中継路 21を有するエアガンを利用し、該エアーガ ンの先端に、圧力測定手段としての圧力計 4と、該圧力計 4の入口側に逆止弁 13と、 出口側に被検査物としてのラヂエーター 5に空気を送り込むためのゴム管 15とを取り 付けたものを 1対としたものを組み込んでいる。この組み込みは、逆止弁 13がエアー ガンの先端の内部に入るように、ねじ込み取り付けることにより行っている。エアーガ ンの開閉バルブ 12と圧力計 4の逆止弁 13の間には抜き穴 14を設けている。開閉バ ルブ 12のレバー及び抜き穴 14の相対位置は、これらが片手のみで操作し難くなるよ うに設定されている。これにより、リークダウンテスター 20を使用者に両手で操作させ るようにし、使用者がその空いた手や顔等の身体を被検査物としてのラヂエーターに 近づけることを防止するようにしている。プラグ 10における空気の流路の下流側開口 には、流量調整ネジ受け 16としての雌ネジが螺設されており、該流量調整ネジ受け 16には、流量調整ネジ 11が螺入される。流量調整ネジ 11は、そのネジ 17の先が斜

As shown in the cross-sectional view of FIG. 3, the leak down tester 20 is interposed in the middle of a flow path of air as a fluid, and has an air gun having a relay path 21 that relays the air from the upstream side to the downstream side. In order to send air into the pressure gauge 4 as a pressure measuring means at the tip of the air gun, the check valve 13 at the inlet side of the pressure gauge 4, and the radiator 5 as an object to be inspected at the outlet side A pair with a rubber tube 15 attached is incorporated. This incorporation is performed by screwing so that the check valve 13 enters the inside of the tip of the air gun. A vent hole 14 is provided between the air gun open / close valve 12 and the check valve 13 of the pressure gauge 4. The relative positions of the lever of the open / close valve 12 and the punch hole 14 are set so that they are difficult to operate with only one hand. This allows the user to operate the leak-down tester 20 with both hands, and prevents the user from approaching the empty hand, face, or other body to the radiator as the object to be inspected. A female screw as a flow rate adjusting screw receiver 16 is screwed into the downstream side opening of the air flow path in the plug 10, and the flow rate adjusting screw 11 is screwed into the flow rate adjusting screw receiver 16. The flow adjustment screw 11 Therefore, the deeper it is screwed into the flow rate adjusting screw receiver 16, the more the air flow is restricted. A perspective view of the plug 10 and the flow rate adjusting screw 11 is shown in FIG. In this way, the flow rate of the air flowing in from the compressor 1 can be adjusted by adjusting the screwing amount of the flow rate adjusting screw 11 with respect to the flow rate adjusting screw receiver 16, and the compressor 1 as a high pressure fluid supply means can be adjusted. The inflowing air can be throttled to a very weak level with the flow adjustment screw 11 of the plug 10. The flow rate adjusting screw receiver 16 and the flow rate adjusting screw 11 are an inflow adjusting valve as a flow rate reducing means for restricting the air flow.
[0034] ここで、中継路 21と、流量調整手段としての流入調整弁と、抜き穴 14とが、流体とし ての空気の流路の途中部に介装され、該途中部における上流側に対して下流側の 空気の圧力が減少するように調整するための流体圧力調整器 19である。この流体圧 力調整器 19は、空気の圧力に逆らって手で押さえることにより抜き穴 14からの空気 の流出を抑制又は停止可能、かつ、手を離すことにより抜き穴 14からの空気を放流 可能となるように空気の流れを制御可能に構成されている。 [0034] Here, the relay path 21, the inflow regulating valve as the flow rate adjusting means, and the vent hole 14 are interposed in the middle of the flow path of the air as the fluid, and upstream of the middle section. On the other hand, a fluid pressure regulator 19 for adjusting the downstream air pressure to decrease. This fluid pressure regulator 19 can suppress or stop the outflow of air from the hole 14 by holding it against the air pressure by hand, and can release the air from the hole 14 by releasing the hand. The air flow is configured to be controllable.
[0035] 次に、本発明に係るリークダウンテスター 20の使用方法について説明する。まず、 ラヂエーター 5に本発明のエアーガンのゴム管 15を差し込み、プラグ 10にコンプレツ サーホースを接続する。次いで、コンプレッサー 1を作動させ、エアーガンの開閉バ ルブ 12のレバーを一方の手で握った時に先端に流れる空気を全て抜き穴 14力も抜 けさせる。このとき、抜き穴 14からシユーという音がするので、これにより、抜き穴 14か ら空気が漏れていることを確認できる。次いで、その微弱な空気の流れを他方の手の 指 9で塞ぐと、エアーガン内部に圧力が発生し、逆止弁 13、ゴム管 15を通じて、ラヂ エーター 5に圧力が掛かる。ラヂエーター 5内が所望の圧力になるまでは、開閉バル ブ 12のレバーを一方の手で握りっぱなしで、他方の手の指 9を使って抜き穴 14を閉 じたり開いたりしてラヂエーターへの空気の圧力を調整する。そして、ラヂエーター 5 内が所望の圧力になったときは、他方の手の指 9を抜き穴 14から離してから、一方の 手を開閉バルブ 12のレバーから離すようにする。このように、エアーガンの開閉バル ブ 12のレバーをだけを握ってもコンプレッサー 1の高い圧力がラヂエーター 5に加わ らない安全な構造となっている。そして、エアーガン内部の空気量は微弱に絞ってあ り、該微弱な流れの圧力の上昇を圧力計 4を確認しながら緩やかにゴム管 15に送り、
ラヂエーター 5に任意の圧力を得るようにしている。ラヂエーター 5に送り込んだ空気 は開閉バルブ 12のレバーと抜き穴 14から手を離しても圧力計 4の入口の逆止弁 13 の作用により保たれる。 [0035] Next, a method for using the leak down tester 20 according to the present invention will be described. First, the rubber tube 15 of the air gun of the present invention is inserted into the radiator 5, and the compressor hose is connected to the plug 10. Next, Compressor 1 is operated, and when the lever of the air gun open / close valve 12 is grasped with one hand, all the air flowing to the tip is also released. At this time, since a noise is heard from the punch hole 14, it can be confirmed that air is leaking from the punch hole 14. Next, when the weak air flow is blocked by the finger 9 of the other hand, pressure is generated inside the air gun, and pressure is applied to the radiator 5 through the check valve 13 and the rubber tube 15. Until the pressure inside the radiator 5 reaches the desired pressure, hold the lever of the open / close valve 12 with one hand and use the finger 9 of the other hand to close or open the hole 14 to the radiator. Adjust the air pressure. When the pressure inside the radiator 5 reaches a desired pressure, the finger 9 of the other hand is released from the hole 14 and then one hand is released from the lever of the opening / closing valve 12. In this way, even if the lever of the open / close valve 12 of the air gun is held, the high pressure of the compressor 1 is not applied to the radiator 5 in a safe structure. The amount of air inside the air gun is reduced to a very low level, and the increase in the pressure of the weak flow is gently sent to the rubber tube 15 while checking the pressure gauge 4, Arbitrary pressure is applied to the radiator 5. The air sent to the radiator 5 is maintained by the action of the check valve 13 at the inlet of the pressure gauge 4 even if the lever of the opening / closing valve 12 and the release hole 14 are released.
[0036] なお、図 4の斜視図に示すように、コンプレッサー 1の使用できない場合のために、 圧力計 4、逆止弁 13、ゴム管 15を一対とし、エアーガンの先端部分力 外せる構造と することもできる。これとともに、逆止弁 13として自転車のバルブ (例えば虫ゴムを有 するバルブ)を使用することにより、そのバルブに低圧流体供給手段としての自転車 用のポンプ 22 (タイヤチューブに空気を入れるポンプ)のノズル 23を繋ぐことができる ようにしている。これにより、高圧流体供給手段としてのコンプレッサー 1がない場合 でも、単体で自転車のポンプ 22によりラヂエーター 5に加圧できるようになる。 [0036] As shown in the perspective view of FIG. 4, when the compressor 1 cannot be used, the pressure gauge 4, the check valve 13, and the rubber tube 15 are paired so that the force at the tip of the air gun can be removed. You can also. At the same time, by using a bicycle valve (for example, a valve having rubber rubber) as the check valve 13, the bicycle pump 22 (pump that puts air into the tire tube) as a low-pressure fluid supply means to the valve is used. The nozzle 23 can be connected. As a result, even if the compressor 1 as a high-pressure fluid supply means is not provided, the radiator 5 can be pressurized by the bicycle pump 22 alone.
[0037] また、リークダウンテスター 20の故障の有無を検査するには、接続口力ものみ内部 に空気を注入可能なテスト容器を用いる。このテスト容器の接続口に、リークダウンテ スター 20のゴム管 15を接続し、ラヂエーター 5の圧力検査と同様の要領でリークダウ ンテスター 20を操作する。テスト容器力も空気が漏れることはないので、開閉バルブ 12のレバーと抜き穴 14から手を離したときに、テスト容器に送り込んだ空気の圧力が 保持されないことが圧力計 4により確認できる場合は、リークダウンテスター 20が故障 していることが判る。なお、このテスト容器に、封又は蓋がされた第二の接続口を設け ておくこともできる。この封又は蓋を開いて、該第二の接続口と、ラヂエーター 5のォ 一バーフローパイプ 6とをゴム管等のホースで接続するとともに、接続口にゴム管 15 を接続すれば、該テスト容器を空気の緩和容器として使用することもできる。 [0037] Further, in order to inspect whether there is a failure in the leak down tester 20, a test container capable of injecting air only into the connection port force is used. The rubber tube 15 of the leak down tester 20 is connected to the connection port of this test container, and the leak down tester 20 is operated in the same manner as the pressure test of the radiator 5. Since the test container force does not leak air, when the pressure gauge 4 can confirm that the pressure of the air sent to the test container is not maintained when the lever of the open / close valve 12 and the release hole 14 are released, It can be seen that the leak down tester 20 has failed. The test container may be provided with a second connection port that is sealed or covered. When this seal or lid is opened, the second connection port and the overflow pipe 6 of the radiator 5 are connected by a hose such as a rubber tube, and the rubber tube 15 is connected to the connection port. The container can also be used as an air relaxation container.
[0038] また、図 7は、本発明のリークダウンテスター 20を被検査物としてのエンジンのシリ ンダー 25内の漏れ検査に使用する方法を示している。本例のエンジンのシリンダー 25内における漏れは、シリンダー 25及びピストン 26の間、シリンダー 25、ガスケット 2 7及びシリンダーヘッド 28の間や、吸気ノ レブ 29や、排気バルブ 30等に生じた隙間 力 起こる。エンジンのシリンダー 25内の圧縮圧力の既定値は約 IMPa程度であり、 シリンダー 25内の漏れ具合を知るためにシリンダー 25内に注入する空気の圧力は 0 . 1〜0. 14MPa程度であり、本発明のリークダウンテスター 20により十分得られる。 この場合、リークダウンテスター 20は、そのゴム管 15の先端に、点火プラグのネジ穴
31にねじ込み可能に構成された空気挿入金具 32を装着して使用する。そして、シリ ンダー 25内に連通している点火プラグのネジ穴 31に空気挿入金具 32をねじ込み、 シリンダー 25内が所定圧力になるように圧力計 4で確認しながら空気をシリンダー 25 内に注入する。そして、リークダウンテスター 20を取り付けたままの状態で所定時間 が経過した後、シリンダー 25内の圧力低下を圧力計 4により計測することにより、シリ ンダー 25内の漏れ具合を計測すれば、エンジンの疲労度が判断できる。一般的に エンジンの疲労度を知るにはコンプレツシヨンゲージを取り付けてエンジンの圧縮圧 力を計測し既定値と比較してシリンダー 25内の漏れ具合で判断するが、この作業は セルを回しながらコンプレツシヨンゲージを最高圧力にする必要があり、セルを廻す 作業員とコンプレツシヨンゲージを見る作業員が二人いるが、本発明によれば作業員 一人で対応できる。 FIG. 7 shows a method of using the leak down tester 20 of the present invention for leak inspection in the cylinder 25 of the engine as an object to be inspected. Leakage in the cylinder 25 of the engine of this example occurs between the cylinder 25 and the piston 26, between the cylinder 25, the gasket 27, and the cylinder head 28, and the clearance force generated in the intake valve 29, the exhaust valve 30, etc. . The default value of the compression pressure in the cylinder 25 of the engine is about IMPa, and the pressure of the air injected into the cylinder 25 to know the leakage in the cylinder 25 is about 0.1 to 0.14 MPa. It is sufficiently obtained by the leak-down tester 20 of the invention. In this case, the leak-down tester 20 has a spark plug screw hole at the tip of its rubber tube 15. Install the air insertion bracket 32 that can be screwed onto 31. Then, insert the air insertion bracket 32 into the screw hole 31 of the spark plug communicating with the cylinder 25, and inject air into the cylinder 25 while checking with the pressure gauge 4 so that the inside of the cylinder 25 becomes a predetermined pressure. . Then, after a predetermined time has passed with the leak down tester 20 attached, the pressure drop in the cylinder 25 is measured by the pressure gauge 4 to measure the leak condition in the cylinder 25. The degree of fatigue can be judged. Generally, in order to know the degree of engine fatigue, a compression gauge is attached and the compression pressure of the engine is measured and compared with the default value to determine the degree of leakage in the cylinder 25. This work is done while turning the cell. The compression gauge needs to be at the maximum pressure, and there are two workers who turn the cell and two workers who look at the compression gauge. According to the present invention, one worker can handle it.
[0039] 以上のように構成された本実施形態の流体圧力調整器 19によれば、次の効果が 得られる。 According to the fluid pressure regulator 19 of the present embodiment configured as described above, the following effects can be obtained.
(a)空気の圧力を手に感じながら、該空気の圧力を調整することができるので、流体 圧力調整器 19の下流側に過大な圧力を加えることを防止できる。また、手の力で抜 き穴 14を閉じたままに保持することが可能な空気の圧力には限界があり、該限界の 圧力になると手が押し返されて抜き穴 14から空気が放出され、それ以上に圧力が上 昇することが防止されるようになって!/ヽる。 (a) Since the pressure of the air can be adjusted while feeling the pressure of the air by hand, it is possible to prevent an excessive pressure from being applied to the downstream side of the fluid pressure regulator 19. In addition, there is a limit to the pressure of air that can hold the punch hole 14 closed with the force of the hand, and when the limit pressure is reached, the hand is pushed back and air is released from the punch hole 14. It will prevent the pressure from rising further!
(b)構造が簡単で、少ない部品で構成できるので、軽量に構成でき可搬性ゃ機動性 を向上させたり、信頼性を向上させたり、低コストに提供したりすることができる。 (b) Since the structure is simple and can be configured with a small number of parts, it can be configured to be lightweight and can be portable, improving mobility, improving reliability, and providing at low cost.
[0040] また、本実施形態のリークダウンテスター 20によれば、本発明エアーガンのゴム管 15をラヂエーター 5に差し込み、プラグ 10にコンプレッサーホースを接続し、開閉バ ルブ 12のレバーを握るだけではラヂエーター 5には圧力がまったく掛からず、微弱に 抜き穴力も流れ出る空気を指 9で塞ぐことで、緩や力な圧力の上昇を圧力計 4で確認 しながらラヂエーター 5に任意の検査圧力が得られる。 [0040] Further, according to the leak down tester 20 of the present embodiment, simply inserting the rubber tube 15 of the air gun of the present invention into the radiator 5, connecting a compressor hose to the plug 10, and grasping the lever of the opening / closing valve 12 only causes the radiator. No pressure is applied to 5 and the air that weakly pierces through the air is blocked with fingers 9, so that an arbitrary inspection pressure can be obtained at radiator 5 while confirming a moderately strong pressure rise with pressure gauge 4.
[0041] そして、本発明は、ラヂエーター 5の圧力検査のみならず、本発明エアーガン出口 のゴム管 15でラヂエーター 5注水口横のオーバーフローパイプ 6により、ラヂエータ 一 5内部に圧力を送り込んだ後、それを外し、ラヂエーター 5内部圧力の変化をキヤ
ップ 7開放時の内部圧力の噴出し音、ラヂエーターホースの膨らみで確認することで 、注水口及びそこに取り付けられたキャップ 7の保持力の良否判断が可能である。 [0041] And the present invention is not only for checking the pressure of the radiator 5 but also for feeding the pressure into the radiator 5 by the rubber pipe 15 at the outlet of the present invention by the overflow pipe 6 next to the radiator 5 water inlet. Remove the radiator 5 and measure the change in internal pressure. By checking the sound of the internal pressure that is blown when the top 7 is opened and the swelling of the radiator hose, it is possible to judge whether the holding power of the water inlet and the cap 7 attached thereto is good or bad.
[0042] このように、本発明を具体ィ匕したリークダウンテスター 20によれば、自動車整備工 場において、エアー工具と同様な扱いで、ラヂエーター 5の水漏れ検査が出来るよう になり、コンプレッサー 1のない場合も一般に普及している安価な自転車のポンプ 22 を使用して加圧検査が出来るようになった。 [0042] Thus, according to the leak down tester 20 embodying the present invention, it becomes possible to perform a water leak inspection of the radiator 5 in the same manner as an air tool at an automobile maintenance shop. Even when there is no pressure, a low-pressure bicycle pump 22 that is widely used can be used for pressure testing.
[0043] 従って、本実施形態のリークダウンテスター 20によれば、次の効果が得られる。 Therefore, according to the leak down tester 20 of the present embodiment, the following effects can be obtained.
(a)ラヂエーター 5に注入する空気の圧力を手で感知しながら、該空気の流れを調節 するようにしているので、ラヂエーター 5に過大な圧力をカ卩えることを防止でき、これ によりラヂエーター 5が損傷することを防止できる。また、手の力で抜き穴 14を閉じた ままに保持することが可能な空気の圧力には限界があり、該限界の圧力になると手が 押し返されて抜き穴 14から空気が放出され、それ以上に圧力が上昇することが防止 されるようになつている。 (a) Since the air flow is adjusted while detecting the pressure of the air injected into the radiator 5 by hand, it is possible to prevent the radiator 5 from being charged with excessive pressure. Can be prevented from being damaged. In addition, there is a limit to the pressure of air that can be held with the punch hole 14 closed by hand force, and when the limit pressure is reached, the hand is pushed back and air is released from the punch hole 14, Further increase in pressure is prevented.
(b)構造が簡単で、少ない部品で構成できるので、軽量に構成でき可搬性ゃ機動性 を向上させたり、信頼性を向上させたり、低コストに提供したりすることができる。 (b) Since the structure is simple and can be configured with a small number of parts, it can be configured to be lightweight and can be portable, improving mobility, improving reliability, and providing at low cost.
