Abstract

PURPOSE:To obtain a ram pressure meeting a vehicle running speed to regulate an air intake quantity by providing plural movable pieces in parallel at a ventilating opening, and selectively opening and closing each movable piece. CONSTITUTION:Plural movable pieces 3, 4 are provided in parallel between both the side plates 1, 2 of a Pitot tube-type ventilating opening 10 protruding outward from the outer face of a car body, and the side plates 1, 2 pivotally support rotary shafts 6, 7 fixed to the movable pieces 3, 4. Arms 11, 12 fixed to each end of the rotary shafts 6, 7 pivotally support the piston rod of each of actuators 8, 9. In the case of using the ventilating opening 10, for instance as an air intake, the movable piece 3 on an upstream side in a running direction of the movable pieces 3, 4 is rotated in an opening direction to obtain ram pressure meeting the running speed of a vehicle for regulating an air intake quantity. In the case where the expected ram pressure can not be obtained during the stopping of the car, the movable pieces 3, 4 are rotated in their opening directions to enlarge their opening quantities for drawing the sufficient quantity of the air through a small fan provided for the low ram pressure.

Rotate it to obtain ram pressure according to the vehicle's running speed and adjust the air intake amount. Also, if you cannot expect ram pressure such as when the vehicle is stopped,
Rotate each movable piece in the opening direction to increase the opening amount,
A small fan installed for low ram pressure draws in sufficient air. Furthermore, when the ventilation opening is used as an air outlet I, the flow of air along the outer surface of the vehicle body around the ventilation opening is reversed. In this case, either make each movable piece protrude greatly into the outside air flow and increase the negative pressure at the air outlet to increase the exhaust flow rate, or rotate each movable piece in the opposite direction to increase the negative pressure at the air outlet. Since it is made smaller and the exhaust flow rate is reduced, the same structure can be used for the air intake and air outlet, which has the effect of reducing costs.
