本発明は、排気タービン過給機に係り、特に内燃機関の
急激なスロットル弁全閉時に発生するサージ音を消去す
るのに好適な過給機の構造に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an exhaust turbine supercharger, and in particular to a supercharging device suitable for eliminating surge noise generated when a throttle valve of an internal combustion engine is abruptly fully closed. Regarding the structure of the machine.

ンルーム内が複雑になるという欠点がある。The conventional method for preventing supercharging air surging is
As shown in No. 2-59211 and Japanese Patent Publication No. 55-66614, the piping system outside the turbocharger is taken into consideration to prevent surge noise by releasing the supercharging pressure into the compressor inlet or exhaust muffler when surging occurs. . This method requires valves between each piping from the turbine outside the supercharger to the inlet/outlet of the compressor, which has the disadvantage that the piping becomes long and at the same time the inside of the engine room becomes complicated.

上させる回転機械である。この過給機をガソリンエンジ
ンに適用した場合、エンジンの減速時に吸入空気調節用
のスロットル弁を急閉した時に次に述べるような不具合
が発生する。An exhaust turbine supercharger is a rotating machine that uses exhaust gas from the engine to rotate a turbine, and uses a compressor located coaxially with the turbine to send compressed air into the engine, increasing the engine's output. When this supercharger is applied to a gasoline engine, the following problem occurs when the throttle valve for adjusting intake air is suddenly closed during engine deceleration.
すなわち、減速時にスロットル弁を急閉すると排気ガス
量は急速に減少するにも拘らず、タービンはその慣性で
一瞬の間高回転を維続し、閉塞状態の吸気系への空気の
圧縮を続けて過給圧が高くなると同時に空気が流れなく
なる。この結果コンプレッサがサージング領域に入る。In other words, even though the amount of exhaust gas decreases rapidly when the throttle valve is suddenly closed during deceleration, the turbine maintains high rotation for a moment due to its inertia, continuing to compress air into the blocked intake system. As soon as the boost pressure increases, air stops flowing. As a result, the compressor enters the surging region.
コンプレッサがサージング領域に入ると過給機が損傷す
るおそれがあると共に、異音が発生する。この異音は、
運転者に不快感を与える。If the compressor enters the surging region, the supercharger may be damaged and abnormal noises may be generated. This strange noise is
Causes discomfort to the driver.
このサージングを防止する方法として、前記した様に特
公昭５２−５９２１１号や特公昭５５−６６６１４号が
ある。As mentioned above, Japanese Patent Publications No. 52-59211 and Japanese Patent Publication No. 55-66614 are methods for preventing this surging.
これ等は、コンプレッサ出口とスロットル弁までの配管
の途中から電磁弁や吹出弁を中継しコンプレッサの入口
へ通ずる配管へつないだり、又消音器につないだりして
、スロットル弁の急閉時に電磁弁や吹出弁を強制的に開
け、サージングの防止を計っている。These can be connected to the piping leading to the compressor inlet by relaying a solenoid valve or blow-off valve from the middle of the piping between the compressor outlet and the throttle valve, or connected to a silencer, so that when the throttle valve is suddenly closed, the solenoid valve In order to prevent surging, the valves are forcibly opened.
このためエンジンルーム内の配管が複雑となり高価とな
る。本発明の目的は、サージングを防止すると供に安価
な過給エンジンを作ることにある。Therefore, the piping inside the engine room becomes complicated and expensive. An object of the present invention is to prevent surging and to create an inexpensive supercharged engine.

はディフューザ部を連通出来る様にし、スロワ１−ル弁
の急閉時にコンプレッサケースに内蔵の前記電磁弁を開
くことにより、達成される。The above purpose is to build a solenoid valve into the compressor case of the exhaust turbine turbocharger so that the inlet and outlet of the compressor blades or the diffuser can communicate with each other. This is achieved by opening the solenoid valve.

磁弁をスロットル弁が全開であるという信号を受けて、
開くのでサージングに入らず異音を発生しない。If the Scot 1 Hell valve is suddenly closed during deceleration, the compressed air in the compressor will no longer flow and the compressor will enter a surging state. However, since the supercharger of the present invention has a built-in solenoid valve that communicates the outlet and inlet of the compressor, the solenoid valve is activated when receiving a signal that the throttle valve is fully open.
Since it opens, there is no surging and no abnormal noise.
又過給機内でコンプレッサ入口と出口を連通ずるので他
からの配管がなくエンジンルーム内が簡潔となる。Furthermore, since the compressor inlet and outlet are communicated within the supercharger, there is no piping from other places, making the interior of the engine room simpler.
以下、本発明の一実施例を第１図〜第４図により説明す

ている。Fig. 4 shows the exhaust turbine supercharger of the present invention? It is a system diagram of the engine used. The compressor 5 of the supercharger 3 has an inlet connected to an air cleaner (including an air amount measuring device) 18 . Further, the outlet of the compressor 5 is connected to a manifold of the engine 13 through a throttle valve 20. The outlet of the turbine is connected to an exhaust muffler, which is not shown in the figure. An inlet of the turbine 15 is connected to an exhaust manifold 14 of the engine 13.

結果サージ音が発生しない過給機となる。In the above configuration, when the throttle valve 21 is suddenly closed to decelerate from the operating state due to turbocharging, the flow to the engine 13 is suddenly blocked by the sudden closing of the throttle valve 21, so that the flow to the engine 13 is suddenly blocked. Compressor 5 enters surging. However, in the supercharger of the present invention, when the throttle valve 20 is fully opened, the throttle fully open switch 2 indicates the fully open position.
1 operates, a signal is sent from the microcomputer 22 to the coil 10 of the electromagnetic valve 2, and the electromagnetic valve 2 operates to establish communication between the scroll 4 in the compressor case and the inlet 6 of the compressor blade '5. As shown in FIG. 3, the communicating passages 7 and 8 are predetermined to have a minimum size that allows an amount of air to flow without causing surging when the rotor's natural rotational speed falls. This results in a supercharger that does not generate surge noise.

間でも良い。The location communicating with the inlet 6 of the compressor wheel 5 is within the compressor case 1, either in the dufusor section 24 where the compressed air comes out from the compressor wheel 5, in the scroll 4, or between the scroll and the outlet end 25 of the compressor case 1. But it's okay.
