Abstract

Valve de purge pour un compresseur dont les circuits sont raccordés à une chambre 2 d'amenée de l'air comprimé. La pression décolle une membrane 4 de son siège 40 et l'air comprimé remplit ainsi une chambre 6 fermée à sa base par un clapet 9 qui obture une cavité 72 en communication avec un orifice d'échappement 721. Lorsque la pression tombe à zéro dans la chambre d'amenée 2, la membrane est appliquée sur son siège et fait décoller, par l'intermédiaire d'un organe de solidarisation 41, 82, 831, 832, 830 le clapet 9 de son siège 91. L'air s'échappe alors brutalement par l'orifice 721, à cause de l'effet de turbulence qui se manifeste dans la chambre inférieure 720.
