FIELD: ventilation.
SUBSTANCE: invention relates to a ventilation or check valve for ventilation or outlet openings of compressed air apparatus in vehicles. Such valves comprise a membrane disc made of flexible material which, when pressure drops, rises above the seat and opens the opening between the inlet and outlet spaces. Novelty of the invention is that, a plurality of spaced-apart holders are provided on the valve housing and locally hold down the outer region of the membrane disc against the valve seat. Only the parts of the disc located between the holders can rise above the seat.
EFFECT: technical result consists in reducing the noise level during valve operation, reducing throttling effects, increasing the reliability of valve operation.
