The throttle valve 1 is connected to the first passage 14 communicating with the throttle valve 1.
5 is provided, and a supercharger 16 is provided between the throttle valve 15 and the air cleaner 11. This supercharger 16 is a supercharger connected to the engine 12 by a belt 17 and driven. The first passage 14 between the turbocharger 16 and the throttle valve 15 on the downstream side of the turbocharger 16 presents a surge tank chamber 18, and the surge tank chamber 18 and the upstream side of the turbocharger 16 The first passage 14 between a certain supercharger 16 and the air cleaner 11 is
They are communicated by a passage 19. A first control valve 20 is provided at the connection between the second passage 19 and the surge tank chamber 18.
is provided to open and close the mouth 21 of the surge tank chamber 18. This first control valve 20 includes a valve lid 22, a diaphragm 23 that interlocks the valve lid 22, and a diaphragm 23 that interlocks the valve lid 22.
A spring 2 that acts on the valve lid 22 and pushes the valve cover 22 toward the opening 21 side.
4. Consists of a guide portion 25 of the valve lid 22, which constitutes a first pocket 26 into which the spring 24 is mounted, and a second pocket 27 formed by the diaphragm 23 and the guide portion 25. The first pocket 26 communicates with the first passage 14 on the downstream side of the throttle valve 15 between the throttle valve 15 and the combustion chamber 13 via a third passage 28 . 2nd pocket 27
communicates with the surge tank chamber 18 through a fourth passage 29. A second control valve 30 is arranged in the fourth passage 29 . The second control valve 30 includes a port 32 that communicates with the air cleaner 31, a valve cover 33 that opens and closes the port 32, a diaphragm 34 that interlocks the valve cover 33, and a spring 35 that acts on the diaphragm 34 and pushes the valve cover 33 toward the port 32. , consisting of a guide portion 36 of a valve lid 33,
A third pocket 37 in which a spring 35 is mounted, a fourth pocket 38 formed by a diaphragm 34 and a guide portion 36 are constructed. The third pocket 37 communicates with the fourth passage 29. A fourth pocket 38 communicates with the atmosphere.
以上の構成において、エンジン１２がアイドル

サージタンク室１８に連通する。 In the above configuration, when the engine 12 is idling or decelerating, the pressure in the first passage 14 on the downstream side of the throttle valve 15 is in a negative pressure state, but the pressure in the surge tank chamber 18 is in a positive pressure state. At this time,
Since the second control valve 30 is in the closed state, the surge tank chamber 1
The second pressure signal in 8 enters the second pocket 27 through the fourth passage 29, while the third passage 28 becomes negative pressure, and the first pressure signal of negative pressure enters the first pocket 26. As a result, the diaphragm 23 moves the valve cover 22 upward, opens the mouth 21, and communicates the second passage 19 with the surge tank chamber 18.

閉度が設定され、適正な過給状態が保たれる。 When the engine 12 accelerates rapidly or under high load, the inside of the surge tank chamber 18 and the throttle valve 1
Since the pressures in the first passage 14 on the downstream side of the spring 24 are close to each other, the first and second pressure signals and the spring 24
The valve cover 22 moves according to the setting force, the opening/closing degree of the mouth 21 is set, and an appropriate supercharging state is maintained.

１３へ供給され、エンジン１２は作動し続ける。 When the supercharger 16 is locked or the belt 17 is cut and driving force is no longer transmitted to the supercharger 16, the pressure inside the surge tank chamber 18 becomes negative. Therefore, the inside of the third pocket 37 is also in a negative pressure state, while the inside of the fourth pocket 38 is in an atmospheric state, so the diaphragm 34 moves upward and the valve cover 33 is pulled up. As a result, the port 32 opens and air is supplied from the air cleaner 31 into the fourth passage 29. Therefore, a second pressure signal equivalent to atmospheric pressure is transmitted into the second pocket 27, while a first pressure signal of negative pressure is transmitted into the first pocket 26, so the valve cover 22 is moved upward and the mouth 21 is opened. Therefore, air is supplied to the combustion chamber 13 through the second passage 19, and the engine 12 continues to operate.

Since the valves are controlled using the pressure signal in the passage, it is possible to keep the engine running even in the event of an unexpected supercharger accident such as the supercharger locking up or belt breakage.
