FIELD: transport engineering; vehicle interior ventilation systems. ^ SUBSTANCE: proposed ventilation device includes engine exhaust pipe and air duct communicating with vehicle interior. Novelty is that device is furnished additionally with chamber divided into two spaces by diaphragm made of elastic material or spring-loaded piston. One space of chamber is connected with exhaust pipe, and other space, with air duct. Intake and outlet valves are installed on air duct before chamber and after chamber, respectively. Change-over valve connected with intake manifold of engine can be installed after outlet valve. ^ EFFECT: reliable and simple design providing delivery of air into interior or into engine intake manifold for supercharging, possibility of operation on low power engines. ^ 3 cl, 4 dwg |
