Abstract
Régulateur comportant essentiellement trois chambres disposées coaxialement les unes derrière les autres, à savoir une chambre amont par laquelle pénètre le fluide, une chambre aval, par où le fluide s'échappe, et une chambre intermédiaire, ou de turbulence, séparée de la chambre aval par une cloison, un conduit latéral débouchant par une extrémité dans la chambre aval et par l'autre dans chambre intermédiaire, un piston monté dans la chambre aval entre le débouché du conduit latéral et la cloison de séparation et dont la face aval forme le fond de la chambre aval, une tige solidaire de la face amont et traversant ladite cloison de séparation pour faire saillie dans la chambre intermédiaire, ladite tige ayant une section nettement inférieure à la section du piston, et son extrémité libre étant agencée pour venir obturer quand la tige est déplacée vers l'amont un orifice ménagé dans le fond aval de la chambre amont et faisant communiquer cette dernière avec la chambre intermédiaire. Application à l'alimentation en eau dans les mines.Regulator comprising essentially three chambers arranged coaxially one behind the other, namely an upstream chamber through which the fluid enters, a downstream chamber, through which the fluid escapes, and an intermediate chamber, or turbulence chamber, separated from the downstream chamber by a partition, a lateral duct opening at one end into the downstream chamber and by the other into the intermediate chamber, a piston mounted in the downstream chamber between the outlet of the lateral duct and the separation wall and of which the downstream face forms the bottom of the downstream chamber, a rod integral with the upstream face and passing through said partition wall to protrude into the intermediate chamber, said rod having a section markedly smaller than the section of the piston, and its free end being arranged to close off when the rod is moved upstream an orifice formed in the downstream bottom of the upstream chamber and making the latter communicate with the intermediate chamber. Application to water supply in mines.
