Closed vehicle cab with pressure compensation has swivel-open flap mounted on air outlet and biased towards closed position through magnetic force

摘要

The closed cab has an air outlet with a swivel-open flap (4) as magnetic foil mounted thereon which is biased towards the closed position through a magnetic force. During operation of the vehicle a standard pressure is produced which is increased compared to outside whilst the magnetic force acting towards the closed position of the flap is greater than the pressurised force resulting from the standard pressure and acting towards the opening position of the flap. The flap can be mounted in a separate housing (7) connectable to the vehicle cab. The flap can be mounted in a separate housing (7) connectable to the vehicle cab.
