Description
【０００１】[0001]
本考案はターボチャージャ付内燃機関におけるウェイストゲートバルブ（過給 圧制御弁）の改良に関する。 The present invention relates to improvement of a waste gate valve (supercharging pressure control valve) in an internal combustion engine with a turbocharger.
【０００２】[0002]
この種のウェイストゲートバルブは、図２及び図３（ａ）、（ｂ）に示すよう に、タービンハウジング１に固定されたロッド軸受２に回動可能に嵌合するロッ ド３の図示左端部に、アーム４の基部が符号Ｆで示すように溶接され、アーム４ の可動端（図示下端）にはピン５が直径方向と軸方向に一定の隙間をもって嵌合 され、このピン５の先端小径部にほぼ円板状の弁体６がかしめ又は溶接で取付け られている。 This type of wastegate valve, as shown in FIGS. 2 and 3A and 3B, includes a rod bearing 2 fixed to a turbine housing 1 and a rod bearing 2 rotatably fitted to the left end portion of the rod 3 in the figure. Then, the base of the arm 4 is welded as shown by the symbol F, and the pin 5 is fitted to the movable end (lower end in the drawing) of the arm 4 with a constant gap in the diameter direction and the axial direction. A disc-shaped valve body 6 is attached to the portion by caulking or welding.
【０００３】 このウェイストゲートバルブは、ロッド３の図示右端に固着されたレバー７に よって開閉作動され、図３（ｂ）に閉弁状態を示す。８はタービンハウジング１ に設けた弁座で、弁体６が密着して閉弁している。The wastegate valve is opened / closed by a lever 7 fixed to the right end of the rod 3 in the figure, and the valve closed state is shown in FIG. 3B. Reference numeral 8 is a valve seat provided in the turbine housing 1, and the valve body 6 is in close contact with it to close the valve.
【０００４】 この従来技術では、閉弁時に弁体６の面が弁座８の面にシール性良く密着でき るように、弁体６に固着したピン５がアーム４の可動端に前記直径方向と軸方向 に一定の隙間をもって回転可能に嵌合組立てられている。In this conventional technique, the pin 5 fixed to the valve body 6 is attached to the movable end of the arm 4 in the diametrical direction so that the surface of the valve body 6 can be brought into close contact with the surface of the valve seat 8 when the valve is closed. It is assembled so that it can rotate with a certain clearance in the axial direction.
【０００５】[0005]
そのため、弁体自体がエンジン振動に同期して、または排気ガスの噴出圧力に よって振動し、アーム４が前記隙間によるがたでピン５や弁体６と衝突し、大き な騒音を発生すると共に、耐久性に乏しいという問題点があった。 Therefore, the valve element itself vibrates in synchronization with the engine vibration or by the jet pressure of the exhaust gas, and the arm 4 collides with the pin 5 and the valve element 6 due to the rattling due to the clearance, and a large noise is generated. However, there was a problem of poor durability.
【０００６】 又、ウェイストゲートバルブの可動側がロッド３、アーム４、ピン５及び弁体 ６の４部品から構成されているため、部品の製作費や組立費がかさんで、コスト 高になるという問題点があった。Further, since the movable side of the wastegate valve is composed of four parts of the rod 3, the arm 4, the pin 5 and the valve body 6, the manufacturing cost and assembly cost of the parts are expensive and the cost is high. There was a problem.
【０００７】 そこで、本考案はこれらの問題点を解消できるウェイストゲートバルブを提供 することを目的とする。Therefore, an object of the present invention is to provide a wastegate valve that can solve these problems.
【０００８】[0008]
上記目的を達成するために、本考案のウェイストゲートバルブは、ウェイスト ゲートバルブの可動側（９）を一体的に鋳造すると共に、その弁体部（９ａ）を 球面とし、ロッド部（９ｂ）を直径方向と軸方向に一定のクリアランスをもって 軸受（２）で支承し、かつタービンハウジング（１）の弁座（８Ａ）を前記弁体 部（９ａ）の球面と当接可能なテーパ状としたことを特徴とする。 In order to achieve the above object, the waste gate valve of the present invention is such that the movable side (9) of the waste gate valve is integrally cast, the valve body (9a) is spherical, and the rod portion (9b) is. The bearing (2) is supported with a certain clearance in the diametrical direction and the axial direction, and the valve seat (8A) of the turbine housing (1) is tapered so that it can abut the spherical surface of the valve body (9a). Is characterized by.
【０００９】[0009]
ロッド部（９ｂ）がレバーによって閉弁方向に回動されると、弁体部（９ａ） の球面がタービンハウジング１のテーパ状弁座（８Ａ）に当接閉弁する。 When the rod portion (9b) is rotated in the valve closing direction by the lever, the spherical surface of the valve body portion (9a) comes into contact with the tapered valve seat (8A) of the turbine housing 1 to close the valve.
【００１０】 このとき、ロッド部（９ｂ）と軸受（２）との間の直径方向と軸方向のクリア ランスは、弁体部（９ａ）がテーパ状弁座（８Ａ）とシール性良く密着するよう に作用する。At this time, in the diametrical and axial clearances between the rod portion (9b) and the bearing (2), the valve body portion (9a) closely adheres to the tapered valve seat (8A) with good sealing performance. Acts like.
【００１１】 又、ウェイストゲートバルブの可動部は部品点数が１点に減少する。 又、従来技術でみられた、アームがピンと弁体に衝突することがなくなる。In addition, the movable part of the waste gate valve has the number of parts reduced to one. Further, the arm does not collide with the pin and the valve body, which is seen in the prior art.
【００１２】[0012]
図１（ａ）（ｂ）の実施例で、１はタービンハウジングで、テーパ状の弁座８ Ａが形成されている。２は軸受で、一体に鋳造したウェイストゲートバルブの可 動部９のロッド部（９ｂ）を支承する。７はロッド部（９ｂ）の一端に固着され たレバーである。 In the embodiment of FIGS. 1 (a) and 1 (b), reference numeral 1 is a turbine housing having a tapered valve seat 8A. Reference numeral 2 denotes a bearing, which supports the rod portion (9b) of the movable portion 9 of the integrally cast wastegate valve. Reference numeral 7 is a lever fixed to one end of the rod portion (9b).
【００１３】 可動部９の弁体部９ａは弁座８Ａと対向する側が球面になっている。又、この 弁体部９ａは短いアーム部９ｃで一体的にロッド部９ｂに連結形成されている。 軸受２はロッド部９ｂを直径方向と軸方向に一定のクリアランスをもって支承 し、このクリアランスは閉弁時に弁体部（９ａ）の球面がテーパ状弁座８Ａに密 着し易く作用する。The valve body 9a of the movable portion 9 has a spherical surface on the side facing the valve seat 8A. The valve body 9a is integrally formed with the rod 9b by a short arm 9c. The bearing 2 supports the rod portion 9b with a certain clearance in the diametrical direction and the axial direction, and this clearance acts so that the spherical surface of the valve body portion (9a) easily adheres to the tapered valve seat 8A when the valve is closed.
【００１４】 １０は軸方向のクリアランスを示す。 なお、可動部９の弁体部９ａの球面と、ロッド部９ｂの外周は鋳造後機械加工 で仕上げられる。Reference numeral 10 denotes an axial clearance. The spherical surface of the valve body portion 9a of the movable portion 9 and the outer circumference of the rod portion 9b are finished by machining after casting.
【００１５】[0015]
本考案のウェイストゲートバルブは上述のように構成されているので、弁体部 と弁座とが密着し易く、一体バルブであってもシール性を損うことが無い。 Since the waste gate valve of the present invention is configured as described above, the valve body portion and the valve seat are easily brought into close contact with each other, and even if it is an integrated valve, the sealing performance is not impaired.
【００１６】 アーム部が弁体部と一体的で、これらを連結するピンがないので、バルブ自体 が振動せず、騒音低減と耐久性向上の効果がある。 又、可動部の部品点数が４点から１点に減少されるので、部品の製作費や組立 費が低減され大巾なコスト低減ができる。Since the arm part is integral with the valve body part and there is no pin connecting them, the valve itself does not vibrate, and noise and noise are improved. Further, since the number of parts of the movable part is reduced from four to one, the manufacturing cost and the assembly cost of the parts are reduced, and the cost can be greatly reduced.
