サージタンク。 In an intake surge tank provided between an intake valve and a throttle valve of an engine, the inside of the tank is divided into an intake chamber and a pressure regulating chamber by an elastically maintained diaphragm, and the inlet of the intake chamber is connected to the throttle valve. The outlet is communicated with the intake valve, and the pressure regulation chamber is provided with a throttle and a check valve, and when the throttle valve is opened, the diaphragm is pushed toward the pressure regulation chamber by the pressure increase in the intake chamber, and the air in the pressure regulation chamber is After being throttled, the air is slowly released into the atmosphere, and the volume of the intake chamber gradually increases.When the throttle valve is closed, the diaphragm is pushed toward the intake chamber due to the decrease in pressure in the intake chamber, and the atmosphere is throttled and a non-return check occurs. A variable capacity surge tank characterized by rapidly entering a pressure regulating chamber through a valve, thereby rapidly reducing the volume of an intake chamber.
