御装置。 A positive and negative pressure control device for returning pressurized air downstream of a supercharger to an intake area between a throttle valve disposed upstream of the supercharger and the supercharger, the a port communicating downstream of the gear, a room communicating with the port, a bypass passage connecting the room and the intake area, a diaphragm chamber and a diaphragm back pressure chamber partitioned by a diaphragm, and the diaphragm back pressure chamber and the an air passageway connecting the diaphragm chamber and the air intake area; an air passageway connecting the diaphragm chamber and the air intake area; a diaphragm spring that acts on the diaphragm against negative pressure that acts on the diaphragm chamber from the side; a poppet valve that partitions the room and the port and has a through hole; and a positive pressure that acts on the poppet valve from the port side. a poppet valve spring that acts against the poppet valve, a base end that is locked to the diaphragm, a central part that is slidable with respect to the shaft passage, and a poppet valve spring that is loosely inserted into the through hole of the poppet valve. A positive and negative pressure control device for a supercharger, comprising a shaft comprising a tip end portion that is connected to the poppet valve, and a tip head portion that has a back surface periphery in contact with the end surface on the port side of the poppet valve.
