Description

本開示は、車載空調システムに用いられるシリンダ部品に関する。   The present disclosure relates to a cylinder component used in an in-vehicle air conditioning system.

車載空調システムに用いられるシリンダ部品として、内部に被挿入部品としてキャップが挿入されるものが知られている（下記特許文献１参照）。   As a cylinder part used in an in-vehicle air-conditioning system, one in which a cap is inserted as an inserted part is known (see Patent Document 1 below).

特開２０１５−１５７５７９号公報Japanese Patent Laying-Open No. 2015-157579

特許文献１では、シリンダ部品とキャップとの間にシール部材を設けることは記載されていない。しかしながら、シリンダ部品に冷媒の流出入口が設けられ、シリンダ部品の内部に被挿入部品が挿入される場合、流出入口よりも挿入方向奥側にシール部材を配置することが考えられる。シリンダ部品と被挿入部品との間でシール部材は圧縮されるため、被挿入部品をシリンダ部品内に押し込んでいった場合、流出入口を通り過ぎる箇所でシール部材に余計な力がかからないようにしないと、シール部材が破損しシール切れを起こす恐れがある。   Patent Document 1 does not describe providing a seal member between the cylinder component and the cap. However, when the refrigerant inlet / outlet is provided in the cylinder part and the inserted part is inserted into the cylinder part, it is conceivable to dispose the seal member on the back side in the insertion direction from the inlet / outlet. Since the seal member is compressed between the cylinder part and the part to be inserted, if the part to be inserted is pushed into the cylinder part, it is necessary to prevent an extra force from being applied to the seal member at the place where it passes through the outflow inlet. Otherwise, the seal member may be damaged and the seal may be broken.

本開示は、被挿入部品を挿入する際にシール切れを起こしにくいシリンダ部品を提供することを目的とする。   An object of the present disclosure is to provide a cylinder part that is less likely to cause a seal break when inserting a part to be inserted.

本開示は、車載空調システムに用いられるシリンダ部品であって、被挿入部品が挿入される円筒状の挿入凹部（２０）と、挿入凹部に連通し冷媒を流出させる流出口（２０７，２１１）と、挿入凹部に連通し冷媒を流入させる流入口（２０４，２１４）と、が設けられ、流出口及び流入口の少なくとも一方には、周囲よりも肉厚の形状保持部（２０８，２１５，２２０）が設けられている。   The present disclosure is a cylinder part used in an in-vehicle air conditioning system, and includes a cylindrical insertion recess (20) into which a part to be inserted is inserted, and an outlet (207, 211) that communicates with the insertion recess and flows out the refrigerant. And an inflow port (204, 214) through which the refrigerant flows into the insertion recess, and at least one of the outflow port and the inflow port has a thicker shape holding portion (208, 215, 220) than the surroundings. Is provided.

周囲よりも肉厚の形状保持部を設けることで、例えばろう付け加工時や成形時に、形状保持部が設けられた流出口及び流入口の変形を抑制することが可能となる。シリンダ部品に被挿入部品を挿入するにあたって、間にＯリングといったシール部材を配置する場合、シール部材破損抑制の観点から流出口及び流入口近傍では、被挿入部品に対するシリンダ部品２変形を抑制する必要があるので、形状保持部によってこの変形を抑制することができる。   By providing the shape holding part thicker than the surroundings, it is possible to suppress deformation of the outlet and the inlet provided with the shape holding part, for example, during brazing or molding. When inserting a part to be inserted into a cylinder part, when a seal member such as an O-ring is arranged between them, it is necessary to suppress deformation of the cylinder part 2 with respect to the part to be inserted in the vicinity of the outlet and the inlet from the viewpoint of suppressing damage to the seal member. Therefore, this deformation can be suppressed by the shape holding portion.

本開示によれば、被挿入部品を挿入する際にシール切れを起こしにくいシリンダ部品を提供することができる。   According to the present disclosure, it is possible to provide a cylinder component that is less likely to cause a seal break when inserting a component to be inserted.

The portion of the cylinder part 2 in FIG. 1 shows a cross section taken along the line II in FIG. The cylinder part 2 and the heat exchanger 3 together constitute an in-vehicle air conditioning system. The heat exchanger 3 includes a header tank 31 and a tube 32. The refrigerant flowing into the header tank 31 flows through the tube 32, returns to the header tank 31, and flows out.

シリンダ部品２は、熱交換器３にろう付けされている。シリンダ部品２は、略円筒状の部品である。シリンダ部品２は、その一部が貯液器４に挿入されている。   The cylinder part 2 is brazed to the heat exchanger 3. The cylinder part 2 is a substantially cylindrical part. A part of the cylinder part 2 is inserted into the liquid reservoir 4.

シリンダ部品２には、被挿入部品を挿入するための挿入凹部２０が設けられている。挿入凹部２０に連通するように、冷媒を流出させる流出口２０７，２１１と、冷媒を流入させる流入口２０４，２１４と、が設けられている。   The cylinder part 2 is provided with an insertion recess 20 for inserting a part to be inserted. Outflow ports 207 and 211 through which the refrigerant flows out and inflow ports 204 and 214 through which the refrigerant flows in are provided so as to communicate with the insertion recess 20.

挿入凹部２０には、挿入端である図中上端から、固定部２０１と、シール部２０２と、拡径部２０３と、シール部２０５と、拡径部２０６と、シール部２０９と、拡径部２１０と、シール部２１２と、拡径部２１３と、貯液器接合部２１６と、が設けられている。   The insertion recess 20 has a fixed portion 201, a seal portion 202, a diameter-expanded portion 203, a seal portion 205, a diameter-expanded portion 206, a seal portion 209, and a diameter-expanded portion from the upper end in the figure, which is the insertion end. 210, a seal portion 212, an enlarged diameter portion 213, and a reservoir joint portion 216 are provided.

固定部２０１は、被挿入部品を固定するための部分であって、雌ねじが形成されている。シール部２０２，２０５，２０９，２１２は、被挿入部品との間に設けられるＯリングといったシール部材に当接する部分である。   The fixing part 201 is a part for fixing the part to be inserted, and is formed with a female screw. The seal portions 202, 205, 209, and 212 are portions that abut a seal member such as an O-ring provided between the parts to be inserted.

拡径部２０３には、流入口２０４が連通している。拡径部２０６には、流出口２０７が連通している。流入口２０４には、車載空調システムである冷凍サイクルを流れる冷媒が流入する。流入口２０４に流入した冷媒は、被挿入部品である弁体ユニット（図１に明示せず）によって、流出口２０７側に導かれる。流出口２０７から流出する冷媒は、熱交換器３に流入する。   An inflow port 204 communicates with the enlarged diameter portion 203. An outlet 207 communicates with the enlarged diameter portion 206. The refrigerant flowing through the refrigeration cycle that is the in-vehicle air conditioning system flows into the inflow port 204. The refrigerant that has flowed into the inflow port 204 is guided to the outflow port 207 side by a valve body unit (not explicitly shown in FIG. 1) that is an inserted part. The refrigerant flowing out from the outlet 207 flows into the heat exchanger 3.

図２に示されるように、流入口２０４は、形状保持部２２０を貫通するように設けられている。形状保持部２２０は、周囲よりも肉厚に形成されており、ろう付け時に加熱されても変形量が少なくなるようになっている。   As shown in FIG. 2, the inlet 204 is provided so as to penetrate the shape holding part 220. The shape holding part 220 is formed thicker than the surroundings, and the deformation amount is reduced even when heated during brazing.

形状保持部２２０には、他機器接合部２１９が設けられている。他機器接合部２１９は、熱交換器３以外の機器であって、車載空調システムである冷凍サイクルを構成する圧縮機といった他機器と直接的又は間接的に繋がる部分である。他機器接合部２１９には、取付平面部２１９ａが設けられている。   The shape holding part 220 is provided with an other device joint part 219. The other device joint 219 is a device other than the heat exchanger 3 and is a portion that is directly or indirectly connected to another device such as a compressor constituting a refrigeration cycle that is an in-vehicle air conditioning system. The other device joint portion 219 is provided with a mounting flat surface portion 219a.

図２に示されるように、流出口２０７は、形状保持部２０８を貫通するように設けられている。形状保持部２０８は、周囲よりも肉厚に形成されており、ろう付け時に加熱されても変形量が少なくなるようになっている。   As shown in FIG. 2, the outlet 207 is provided so as to penetrate the shape holding portion 208. The shape holding part 208 is formed to be thicker than the surroundings, and the deformation amount is reduced even when heated during brazing.

形状保持部２０８には、熱交換器接合部２１７が設けられている。熱交換器接合部２１７は、熱交換器３に繋がる部分である。熱交換器接合部２１７には、取付曲面部２１７ａが設けられている。   The shape holding unit 208 is provided with a heat exchanger joint 217. The heat exchanger joint 217 is a part connected to the heat exchanger 3. The heat exchanger joint portion 217 is provided with a mounting curved surface portion 217a.

拡径部２１０には、流出口２１１が連通している。拡径部２１３には、流入口２１４が連通している。流入口２１４には、熱交換器３を流れた冷媒が流入する。流入口２１４に流入した冷媒は、被挿入部品である弁体ユニットによって、流出口２１１側に導かれる。流出口２１１から流出する冷媒は、車載空調システムである冷凍サイクルに流れる。   An outlet 211 communicates with the enlarged diameter portion 210. The inflow port 214 communicates with the enlarged diameter portion 213. The refrigerant that has flowed through the heat exchanger 3 flows into the inflow port 214. The refrigerant that has flowed into the inflow port 214 is guided to the outflow port 211 side by a valve body unit that is an inserted component. The refrigerant flowing out from the outlet 211 flows into the refrigeration cycle that is an in-vehicle air conditioning system.

流入口２０４に対して形状保持部２２０が設けられているのと同様に、図には明示しないけれども流出口２１１に対しても形状保持部が設けられている。   Similarly to the shape holding portion 220 provided for the inflow port 204, a shape holding portion is provided for the outflow port 211, though not explicitly shown in the drawing.

流入口２１４は、形状保持部２１５を貫通するように設けられている。形状保持部２１５は、周囲よりも肉厚に形成されており、ろう付け時に加熱されても変形量が少なくなるようになっている。形状保持部２１５には、熱交換器接合部２１８が設けられている。   The inflow port 214 is provided so as to penetrate the shape holding portion 215. The shape holding portion 215 is formed to be thicker than the surroundings, and the deformation amount is reduced even when heated during brazing. The shape holder 215 is provided with a heat exchanger joint 218.

貯液器接合部２１６は、全長の半分程度が貯液器４の内部に挿入され固定されている。従って、シリンダ部品２は、貯液器接合部２１６が貯液器４に挿入されている以外の部分は、貯液器４から露出している。   About half of the total length of the reservoir joint 216 is inserted and fixed inside the reservoir 4. Therefore, the cylinder component 2 is exposed from the reservoir 4 except for the reservoir junction 216 inserted into the reservoir 4.

図３に、シリンダ部品２に被挿入部品である弁体ユニット５を挿入した状態を示す。シリンダ部品２に弁体ユニット５を挿入すると、シール部２０２にシール部材５１が当接する。同様に、シール部２０５にはシール部材５２が当接し、シール部２０９にはシール部材５３が当接し、シール部２１２にはシール部材５４が当接する。   FIG. 3 shows a state in which the valve body unit 5 that is a part to be inserted is inserted into the cylinder part 2. When the valve body unit 5 is inserted into the cylinder part 2, the seal member 51 comes into contact with the seal portion 202. Similarly, the seal member 52 contacts the seal portion 205, the seal member 53 contacts the seal portion 209, and the seal member 54 contacts the seal portion 212.

弁体ユニット５にシール部材５１，５２，５３，５４を配置し、シリンダ部品２の挿入凹部２０に挿入し始めると、最初にシール部材５４がシール部２０２に当接する。シール部材５４は、シール部２０２と弁体ユニット５との間で圧縮された状態で下降する。流入口２０４が設けられている拡径部２０３に到達すると、シール部材５４の圧縮状態が開放される。拡径部２０３は全周に渡って設けられているので、シール部材５４も均等に開放される。   When the seal members 51, 52, 53, 54 are arranged on the valve body unit 5 and begin to be inserted into the insertion recess 20 of the cylinder part 2, the seal member 54 first comes into contact with the seal portion 202. The seal member 54 descends in a compressed state between the seal portion 202 and the valve body unit 5. When reaching the enlarged diameter portion 203 where the inflow port 204 is provided, the compressed state of the seal member 54 is released. Since the enlarged diameter portion 203 is provided over the entire circumference, the seal member 54 is also equally opened.

その後更に弁体ユニット５が押し込まれると、シール部材５４は、シール部２０５に当接する。シール部材５４は、シール部２０５と弁体ユニット５との間で均等に圧縮される。このように、シール部材５４は、シール部２０２，２０５，２０９で順次均等に圧縮され、拡径部２０３，２０６，２１０で順次均等に開放される。   Thereafter, when the valve body unit 5 is further pushed, the seal member 54 comes into contact with the seal portion 205. The seal member 54 is evenly compressed between the seal portion 205 and the valve body unit 5. As described above, the seal member 54 is sequentially and uniformly compressed by the seal portions 202, 205, and 209, and sequentially opened by the enlarged diameter portions 203, 206, and 210.

一方、拡径部２０３，２０６，２１０が設けられていない場合、シリンダ部品２に弁体ユニット５が押し込まれていくと、流入口２０４を通過する際にシール部材５４が、流入口２０４が形成されている部分でのみ開放され、不均一な開放状態となる。更に弁体ユニット５が押し込まれていくと、シール部材５４が流入口２０４の下側でせん断力が加わる状態となっていまい、破損のおそれがある。本実施形態では、シール部２０２，２０５，２０９に対して、拡径部２０３，２０６，２１０を設けることで、シール部材５１，５２，５３，５４の破損を回避している。   On the other hand, when the enlarged diameter portions 203, 206, and 210 are not provided, when the valve body unit 5 is pushed into the cylinder part 2, the seal member 54 is formed when passing through the inflow port 204, and the inflow port 204 is formed. It is opened only at the part where it is, and it becomes a non-uniform open state. Further, when the valve body unit 5 is pushed in, the seal member 54 is in a state where a shearing force is applied below the inflow port 204, and there is a risk of damage. In this embodiment, damage to the seal members 51, 52, 53, and 54 is avoided by providing the enlarged diameter portions 203, 206, and 210 with respect to the seal portions 202, 205, and 209.

上記したように本実施形態のシリンダ部品２は、車載空調システムに用いられるシリンダ部品であって、被挿入部品である弁体ユニット５が挿入される円筒状の挿入凹部２０と、挿入凹部２０に連通し冷媒を流出させる流出口２０７，２１１と、挿入凹部２０に連通し冷媒を流入させる流入口２０４，２１４とが設けられ、流出口２０７，２１１及び流入口２０４，２１４の少なくとも一方には、周囲よりも肉厚の形状保持部２０８，２１５，２２０が設けられている。   As described above, the cylinder component 2 according to the present embodiment is a cylinder component used in an in-vehicle air conditioning system, and includes a cylindrical insertion recess 20 into which a valve body unit 5 that is an inserted component is inserted, and an insertion recess 20. Outflow ports 207 and 211 through which the refrigerant flows out and inflow ports 204 and 214 through which the refrigerant flows into the insertion recess 20 are provided, and at least one of the outflow ports 207 and 211 and the inflow ports 204 and 214 includes Shape holding portions 208, 215, and 220 that are thicker than the surroundings are provided.

周囲よりも肉厚の形状保持部２０８，２１５，２２０を設けることで、例えばろう付け加工時や成形時に、形状保持部が設けられた流出口２０７，２１１及び流入口２０４，２１４の変形を抑制することが可能となる。シリンダ部品２に被挿入部品である弁体ユニット５を挿入するにあたって、間にＯリングといったシール部材を配置する場合、シール部材破損抑制の観点から流出口２０７，２１１及び流入口２０４，２１４近傍では、被挿入部品である弁体ユニット５に対するシリンダ部品２の変形を抑制する必要があるので、形状保持部２０８，２１５，２２０によってこの変形を抑制することができる。   By providing the shape holding portions 208, 215, and 220 that are thicker than the surroundings, deformation of the outlets 207 and 211 and the inlets 204 and 214 provided with the shape holding portions is suppressed, for example, during brazing or molding. It becomes possible to do. When a sealing member such as an O-ring is arranged between the cylinder part 2 and the valve body unit 5 to be inserted, in the vicinity of the outlets 207 and 211 and the inlets 204 and 214 from the viewpoint of suppressing damage to the sealing member. Since it is necessary to suppress the deformation of the cylinder part 2 with respect to the valve body unit 5 that is an inserted part, the deformation can be suppressed by the shape holding portions 208, 215, and 220.

本実施形態では、挿入凹部２０の内周面には、被挿入部品である弁体ユニット５との間にシール部材を圧接保持することで気密性を保つシール部２０２，２０５，２０９，２１２が設けられており、挿入凹部２０の流出口２０７，２１１又は流入口２０４，２１４を含む内周面には、シール部２０２，２０５，２０９，２１２よりも大径の拡径部２０３，２０６，２１０，２１３が設けられている。   In this embodiment, seal portions 202, 205, 209, and 212 are provided on the inner peripheral surface of the insertion recess 20 to maintain airtightness by holding the seal member in pressure contact with the valve body unit 5 that is a component to be inserted. Provided on the inner peripheral surface including the outlets 207, 211 or the inlets 204, 214 of the insertion recess 20, the enlarged diameter parts 203, 206, 210 having a larger diameter than the seal parts 202, 205, 209, 212. , 213 are provided.

挿入凹部２０に弁体ユニット５を挿入するにあたって、拡径部２０３，２０６，２１０，２１３を設けない場合、シール部２０２，２０５，２０９，２１２において圧縮されたシール部材５１，５２，５３，５４が、流出口２０７，２１１又は流入口２０４，２１４において偏った開放状態となる。その状態で再びシール部２０２，２０５，２０９，２１２において圧縮されると、一部のみにせん断力が集中し破損のおそれがある。そこで、シール部２０２，２０５，２０９，２１２に隣接し、シール部２０２，２０５，２０９，２１２よりも大径の拡径部２０３，２０６，２１０，２１３を設けることで、シール部材５１，５２，５３，５４を均一開放と均一圧縮とが連続する状態におくことができ、破損のおそれを低減することができる。   When inserting the valve body unit 5 into the insertion recess 20, when the enlarged diameter portions 203, 206, 210, 213 are not provided, the seal members 51, 52, 53, 54 compressed in the seal portions 202, 205, 209, 212 are provided. However, the outlets 207 and 211 or the inlets 204 and 214 are in an open state. If the seal portions 202, 205, 209, and 212 are compressed again in this state, the shearing force concentrates on only a part and there is a risk of damage. Therefore, by providing the enlarged diameter portions 203, 206, 210, 213 which are adjacent to the seal portions 202, 205, 209, 212 and have a larger diameter than the seal portions 202, 205, 209, 212, the seal members 51, 52, 53 and 54 can be kept in a state in which uniform opening and uniform compression are continuous, and the risk of breakage can be reduced.

本実施形態では、シール部２０２，２０５，２０９，２１２は、被挿入部品である弁体ユニット５の挿入方向に沿って複数設けられており、挿入方向における奥に行くに従って縮径している。具体的には、シール部２０２よりもシール部２０５の直径が小さく、シール部２０５よりもシール部２０９の直径が小さく、シール部２０９よりもシール部２１２の直径が小さくなるように形成されている。例えば、シール部材５４は最終的にはシール部２１２と当接し圧縮保持されるところ、それよりも手前のシール部２０２，２０５，２０９の直径をシール部２１２よりも小さくしているので、弁体ユニット５を挿入する際の破損を低減することができる。   In the present embodiment, a plurality of seal portions 202, 205, 209, and 212 are provided along the insertion direction of the valve body unit 5 that is a part to be inserted, and the diameter is reduced toward the back in the insertion direction. Specifically, the seal portion 205 is smaller in diameter than the seal portion 202, the seal portion 209 is smaller in diameter than the seal portion 205, and the seal portion 212 is smaller in diameter than the seal portion 209. . For example, when the seal member 54 finally comes into contact with the seal portion 212 and is compressed and held, the diameter of the seal portions 202, 205, and 209 in front of it is smaller than that of the seal portion 212. The damage at the time of inserting the unit 5 can be reduced.

本実施形態では、車載空調システムを構成する熱交換器３に繋がる熱交換器接合部２１７，２１８と、冷媒を貯める貯液器に繋がる貯液器接合部２１６と、が設けられている。更に、車載空調システムを構成する熱交換器３以外の他機器である圧縮機等に繋がる他機器接合部２１９が設けられ、他機器接合部２１９には、他機器と直接的又は間接的に繋がるための平面部である取付平面部２１９ａが設けられている。   In the present embodiment, heat exchanger joints 217 and 218 connected to the heat exchanger 3 constituting the vehicle-mounted air conditioning system, and a liquid reservoir joint 216 connected to the liquid reservoir that stores the refrigerant are provided. Furthermore, the other apparatus joint part 219 connected to the compressor etc. which are apparatuses other than the heat exchanger 3 which comprises a vehicle-mounted air conditioning system is provided, and the other apparatus joint part 219 is connected directly or indirectly with another apparatus. A mounting flat surface portion 219a, which is a flat surface portion, is provided.
