弁状悪にある。Next, the operation of the boost pressure control valve device configured as described above will be explained. In a car and under high-load operating conditions, the throttle valve is close to the fully open state, and due to the supercharging effect of the supercharger fan (not shown), both the intake passage and the intake passage downstream of the throttle valve are at high pressure. It is in a positive pressure state, and the spaces on both sides of the diaphragm (7) are at the same positive pressure. As a result, the diaphragm (7) has a spring (13
) acts on the valve body (9) in the valve closing direction, the seal portion 10) comes into contact with the valve seat (8), and the valve body (9) is in a completely closed state.

の昇圧は防止される。When the above-mentioned medium and high load operation changes to deceleration operation where the throttle valve suddenly closes, the pressure in the intake passage downstream of the throttle valve changes to high negative pressure, and the inside of the case (5) becomes high negative pressure. Also, as long as the fan is rotating, the pressure inside the second bypass passage (4) increases and becomes a high positive pressure, and as a result, the valve body (9) opens against the elastic force of the spring (13), increasing the pressure. Air circulates w1 between the first bypass passage (3) and the second bypass passage (4), and pressure increase on the upstream side of the throttle valve is prevented.
