Description

圧入部材Press-fit member
 本発明は、流体機器の流路に設けられる圧入部材に関するものである。 The present invention relates to a press-fitting member provided in a flow path of a fluid device.
 JP2008-540934Aには、シリンダヘッドに流出弁が設けられた高圧ポンプが記載されている。この流出弁は、シリンダヘッドの流出孔内にばねホルダを圧入することで固定される。 JP 2008-540934A describes a high-pressure pump having a cylinder head provided with an outflow valve. This outflow valve is fixed by press-fitting a spring holder into the outflow hole of the cylinder head.
 JP2008-540934Aに記載の高圧ポンプでは、ばねホルダを流出孔に圧入する際に、ばねホルダの先端部分が流出孔の内壁を削って異物が発生することがある。このような異物が流路内の流体に混入すると、異物が流体とともに流れて流体回路を構成する流体機器のシール部や摺動部に入り込んでしまい、シール部や摺動部においてシール不良や摩耗が発生するおそれがある。 In the high pressure pump described in JP2008-540934A, when the spring holder is press-fitted into the outflow hole, the tip of the spring holder may scrape the inner wall of the outflow hole to generate foreign matter. When such foreign matter is mixed into the fluid in the flow path, the foreign matter flows with the fluid and enters the seal portion or sliding portion of the fluid equipment that constitutes the fluid circuit, resulting in poor sealing or wear at the seal portion or sliding portion. May occur.
 本発明は、上記の問題点に鑑みてなされたものであり、圧入部材を圧入した際に発生する異物の流体への混入を防止することを目的とする。 The present invention has been made in view of the above-described problems, and an object thereof is to prevent foreign matters generated when a press-fitting member is press-fitted into a fluid.
 本発明のある態様によれば、流体機器の流路に設けられる圧入部材は、流体機器の流路に圧入される本体部と、本体部よりも圧入方向側に位置し本体部よりも小径に形成される小径部と、本体部と小径部の間に設けられ周方向に形成される溝と、を備える。 According to an aspect of the present invention, the press-fitting member provided in the flow path of the fluid device includes a main body portion that is press-fitted into the flow path of the fluid device, and a smaller diameter than the main body portion that is positioned on the press-fitting direction side of the main body portion. A small-diameter portion formed, and a groove formed between the main body portion and the small-diameter portion and formed in the circumferential direction.

 以下、図面を参照して、本発明の実施形態に係る圧入部材について説明する。 Hereinafter, a press-fitting member according to an embodiment of the present invention will be described with reference to the drawings.
 圧入部材は、流体機器の流路に設けられる。本実施形態では、流体機器がポンプ1であり、圧入部材がチェック弁10である場合について説明する。 The press-fitting member is provided in the flow path of the fluid device. In the present embodiment, a case where the fluid device is the pump 1 and the press-fitting member is the check valve 10 will be described.
 図1は、ポンプ1に形成された流路2に設けられるチェック弁10を示している。チェック弁10は、カートリッジ式のチェック弁である。 FIG. 1 shows a check valve 10 provided in a flow path 2 formed in the pump 1. The check valve 10 is a cartridge type check valve.
 図1に示すように、チェック弁10は、流路2に固定され内部に貫通路24が形成されたハウジング20と、貫通路24の段差部25に形成された弁座26に対して着座又は離間する球状の弁体30と、弁体30を弁座26に向かって付勢する付勢ばね40と、貫通路24の一端に固定され付勢ばね40の端部を支持するばね受50と、を備える。チェック弁10は、ハウジング20に弁体30、付勢ばね40、及びばね受50を組み付けた後、流路2の開口2bから流路2内に圧入される。 As shown in FIG. 1, the check valve 10 is seated on a housing 20 fixed to the flow path 2 and having a through passage 24 formed therein, and a valve seat 26 formed in a step portion 25 of the through passage 24. A spherical valve body 30 that is spaced apart, a biasing spring 40 that biases the valve body 30 toward the valve seat 26, and a spring receiver 50 that is fixed to one end of the through passage 24 and supports the end of the biasing spring 40. . The check valve 10 is press-fitted into the flow path 2 from the opening 2 b of the flow path 2 after assembling the valve body 30, the urging spring 40, and the spring receiver 50 to the housing 20.
 このように構成されたチェック弁10の機能について説明する。 The function of the check valve 10 thus configured will be described.
 図1における左側から流体が流路2内を流れてくると、チェック弁10の貫通路24内に流体が流入する。そして、流体の圧力が弁体30に作用すると、弁体30は付勢ばね40の付勢力に抗して弁座26から離間する。これにより、流体はチェック弁10を通過して、チェック弁10の下流側へと流れていく。これに対して、図1における右側から流体が流路2内を流れてくると、ばね受50側から貫通路24内に流体が流入する。このとき、弁体30は付勢ばね40の付勢力によって弁座26に着座している。このため、流体はチェック弁10を通過することができない。つまり、チェック弁10は、図1における右側からの流体の流れに対してチェック機能を果たすことになる。このように、チェック弁10は、流路2内の流体の一方向の流れのみを許容するものである。 When the fluid flows in the flow path 2 from the left side in FIG. 1, the fluid flows into the through passage 24 of the check valve 10. When the fluid pressure acts on the valve body 30, the valve body 30 moves away from the valve seat 26 against the biasing force of the biasing spring 40. As a result, the fluid passes through the check valve 10 and flows to the downstream side of the check valve 10. On the other hand, when the fluid flows in the flow path 2 from the right side in FIG. 1, the fluid flows into the through passage 24 from the spring receiver 50 side. At this time, the valve body 30 is seated on the valve seat 26 by the biasing force of the biasing spring 40. For this reason, the fluid cannot pass through the check valve 10. That is, the check valve 10 performs a check function on the fluid flow from the right side in FIG. As described above, the check valve 10 allows only the flow in one direction of the fluid in the flow path 2.
 次に、チェック弁10のハウジング20の具体的な構成について説明する。 Next, a specific configuration of the housing 20 of the check valve 10 will be described.
 図1及び図2に示すように、ハウジング20は、流路2に圧入される本体部21と、本体部21よりも圧入方向側に位置し本体部21よりも小径に形成される小径部22と、本体部21と小径部22の間に設けられ周方向に形成される環状の溝23と、を備える。本体部21と小径部22とは、一体のものとして連続的に形成される。本体部21は、流路2の内周面2aの径よりもわずかに大きな径を有し、小径部22は、流路2の内周面2aよりも小さな径を有する。これにより、流路2の内周面2aと小径部22との間には、隙間Cが存在する。なお、小径部22は、流路2の内周面2aと略同じ径であってもよい。この場合には、隙間Cは存在しないことになる。 As shown in FIGS. 1 and 2, the housing 20 includes a main body 21 that is press-fitted into the flow path 2, and a small-diameter portion 22 that is positioned on the press-fitting direction side of the main body 21 and has a smaller diameter than the main body 21. And an annular groove 23 provided between the main body portion 21 and the small diameter portion 22 and formed in the circumferential direction. The main body portion 21 and the small diameter portion 22 are continuously formed as an integrated body. The main body 21 has a diameter slightly larger than the diameter of the inner peripheral surface 2 a of the flow channel 2, and the small diameter portion 22 has a diameter smaller than that of the inner peripheral surface 2 a of the flow channel 2. Thereby, a gap C exists between the inner peripheral surface 2 a of the flow path 2 and the small diameter portion 22. The small diameter portion 22 may have a diameter substantially the same as the inner peripheral surface 2a of the flow path 2. In this case, the gap C does not exist.
 次に、溝23の機能について、図2を参照しながら具体的に説明する。図2は、溝23付近の拡大図である。 Next, the function of the groove 23 will be specifically described with reference to FIG. FIG. 2 is an enlarged view of the vicinity of the groove 23.
 チェック弁10は、流路2の開口2bから図1、2に示す矢印の方向に圧入されることによって、流路2に固定される。具体的には、本体部21が流路2の内周面2aに圧入されることによって流路2の内周面2aに固定される。 The check valve 10 is fixed to the flow path 2 by being press-fitted in the direction of the arrow shown in FIGS. Specifically, the main body portion 21 is fixed to the inner peripheral surface 2 a of the flow channel 2 by being press-fitted into the inner peripheral surface 2 a of the flow channel 2.
 本体部21を流路2の内周面2aに圧入する際に、本体部21の圧入方向の先端部21Aによって、流路2の内周面2aが削られて異物60が発生することがある。このような異物60が流路2内の流体に混入してしまうと、異物60が流体とともに流れて、例えば、弁体30と弁座26との間のシート部分に噛みこんでしまうおそれがある。異物60がこのようなシート部分に噛みこんでしまうと、閉弁時に弁体30と弁座26との間に隙間ができてしまい、流体が漏れてしまい、チェック弁10の機能が損なわれる。また、異物60が、アクチュエータなどの摺動部分に入り込んでしまうと、摩耗や作動不良の原因となる。 When the main body 21 is press-fitted into the inner peripheral surface 2 a of the flow path 2, the inner peripheral surface 2 a of the flow path 2 may be scraped by the distal end portion 21 </ b> A in the press-fitting direction of the main body 21 to generate the foreign matter 60. . If such foreign matter 60 is mixed into the fluid in the flow path 2, the foreign matter 60 may flow along with the fluid and may be caught in the seat portion between the valve body 30 and the valve seat 26, for example. . If the foreign matter 60 is caught in such a seat portion, a gap is formed between the valve body 30 and the valve seat 26 when the valve is closed, fluid leaks, and the function of the check valve 10 is impaired. Further, if the foreign matter 60 enters a sliding portion such as an actuator, it causes wear and malfunction.
 このため、チェック弁10では、本体部21と小径部22の境界部分に溝23が形成される。これにより、ハウジング20を圧入した際に本体部21の先端部21Aによって発生した異物60は、溝23内において捕捉される。これにより、異物60が流路2内の流体に混入することを防止できる。 Therefore, in the check valve 10, a groove 23 is formed at the boundary portion between the main body 21 and the small diameter portion 22. As a result, the foreign matter 60 generated by the distal end portion 21 </ b> A of the main body portion 21 when the housing 20 is press-fitted is captured in the groove 23. Thereby, it can prevent that the foreign material 60 mixes in the fluid in the flow path 2.
 また、小径部22と流路2の内周面2aとの間の隙間Cを所定の小さな隙間とすることで、溝23内において捕捉された異物60が隙間Cを通過しづらくなるので、異物60が流路2へ流出することを防止できる。 In addition, since the gap C between the small diameter portion 22 and the inner peripheral surface 2a of the flow path 2 is a predetermined small gap, the foreign matter 60 captured in the groove 23 is difficult to pass through the gap C. 60 can be prevented from flowing out into the flow path 2.
 小径部22は、流路2の内周面2aとの間に所定の隙間Cを有するように形成されるため、小径部22と流路2の内周面2aとが接することはない。したがって、小径部22が流路2の内周面2aを削ってしまうことはないため、溝23よりも圧入方向側から異物が発生することはない。 The small-diameter portion 22 is formed so as to have a predetermined gap C between the inner peripheral surface 2a of the flow channel 2 and therefore the small-diameter portion 22 and the inner peripheral surface 2a of the flow channel 2 do not contact each other. Therefore, since the small diameter portion 22 does not scrape the inner peripheral surface 2a of the flow path 2, no foreign matter is generated from the press-fitting direction side of the groove 23.
 以上の本実施形態によれば、以下の効果を奏する。 According to the above embodiment, the following effects are obtained.
 チェック弁10では、本体部21と小径部22の境界部分に溝23が形成される。したがって、チェック弁10のハウジング20を圧入する際に発生した異物60は溝23内に捕捉される。これにより、異物60が流路2内の流体に混入することを防止できる。 In the check valve 10, a groove 23 is formed at the boundary between the main body 21 and the small diameter portion 22. Therefore, the foreign matter 60 generated when the housing 20 of the check valve 10 is press-fitted is captured in the groove 23. Thereby, it can prevent that the foreign material 60 mixes in the fluid in the flow path 2.
 チェック弁10では、小径部22と流路2の内周面2aとの間の隙間Cを所定の小さな隙間が形成される。これにより、溝23内に捕捉された異物60は隙間Cを通過しづらいため、異物60が流路2へ流出することを防止できる。 In the check valve 10, a predetermined small gap is formed in the gap C between the small diameter portion 22 and the inner peripheral surface 2a of the flow path 2. Thereby, since the foreign material 60 captured in the groove 23 is difficult to pass through the gap C, the foreign material 60 can be prevented from flowing out into the flow path 2.
 また、小径部22はハウジング20を圧入する際にガイドとして機能する。これにより、チェック弁10を流路2に対して同軸に圧入することができる。 The small diameter portion 22 functions as a guide when the housing 20 is press-fitted. Thereby, the check valve 10 can be press-fitted coaxially with respect to the flow path 2.
 以上のように構成された本発明の実施形態の構成、作用、及び効果をまとめて説明する。 The configuration, operation, and effect of the embodiment of the present invention configured as described above will be described together.
 圧入部材(チェック弁10)は、流体機器(ポンプ1)の流路2に圧入される本体部21と、本体部21よりも圧入方向側に位置し本体部21よりも小径に形成される小径部22と、本体部21と小径部22の間に設けられ周方向に形成される溝23と、を備える。 The press-fitting member (check valve 10) includes a main body 21 that is press-fitted into the flow path 2 of the fluid device (pump 1), and a small diameter that is located on the press-fitting direction side of the main body 21 and has a smaller diameter than the main body 21. And a groove 23 provided between the main body 21 and the small diameter portion 22 and formed in the circumferential direction.
 この構成によれば、圧入部材(チェック弁10)の本体部21を圧入する際に発生した異物60は、本体部21と小径部22の間に設けられた溝23内に捕捉される。これにより、圧入部材(チェック弁10)を圧入したときに発生する異物60の流路2中の流体への混入を防止できる。 According to this configuration, the foreign matter 60 generated when the main body portion 21 of the press-fitting member (check valve 10) is press-fitted is captured in the groove 23 provided between the main body portion 21 and the small diameter portion 22. Thereby, mixing of the foreign matter 60 generated when the press-fitting member (check valve 10) is press-fitted into the fluid in the flow path 2 can be prevented.
 また、溝23は、本体部21を流路2に圧入させる際に発生する異物60を捕捉するためのものである。 Further, the groove 23 is for capturing the foreign matter 60 generated when the main body 21 is press-fitted into the flow path 2.
 以上、本発明の実施形態について説明したが、上記実施形態は本発明の適用例の一部を示したに過ぎず、本発明の技術的範囲を上記実施形態の具体的構成に限定する趣旨ではない。 The embodiment of the present invention has been described above. However, the above embodiment only shows a part of application examples of the present invention, and the technical scope of the present invention is limited to the specific configuration of the above embodiment.
