Title:
DRAFTER STRUCTURE FOR VENTILATING CAR
Document Type and Number:
Japanese Patent JPS6116120
Kind Code:
A
Abstract:
PURPOSE:To generate the pulsating noise of a drafter and prevent extra-room noise from flowing in by providing a rectification plate that is protruded at a bed side in the opening peripheral section of the drafter located on the surface that is opposed to the bed of the rear panel of a driver room and preventing turbulent flow near the opening section. CONSTITUTION:A rectification plate 4 mounted on the opening 3a peripheral section of a drafter 3 is made of U-shaped sectional frame bodies 40 having width L2 that is almost equal to the gap L1 between a passenger room 1 and a bed 2 and the opening area of the frame body is formed slightly larger than the opening area of the drafter. When the rectification plate 4 is mounted on the periphery of the opening 3a of the drafter, the rectification plate 4 covers the circumference of the drafter opening section and fills the gap L1 between the passenger room 1 and bed 2. Consequently, the opening 3a of the drafter can be disconnected from the external section G2 at the car side. As a result, since an air flow applied on the external section G2 of the side at car running will not flow in the internal space G1 on which the drafter 3 is opened and no turbulent flow is not generated near the opening, the drafter valve will not be pulsated by the turbulent flow at running and no pulsating noise will be generated.
