Definitions

  • the rod 31 is rigidly connected to the piston 12a and carries at its opposite end a flange 32 which co-operates with the seal 20a, these components forming the movable and stationary elements respectively of the regulated fluid valve.
  • the seal 21a is provided to co-operate with the under side of the piston 12a when it is in its lowered position in the same manner and for the same purpose as previously described in respect of the embodiment shown in Figure 1 to 4.
  • the spring 17a urges the piston 12a, rod 31 and flange 32 in a direction to normally close the regulated fluid valve. It should be understood that in both of the embodiments described the spring 17 or 17a may be omitted because when the control pressure drops the pressure of the regulated fluid will cause the piston 12, 12a to rise to close the regulated valve.
  • This construction has the further advantage that when the stop valve is used in association with a screw type compressor after the compressor has been shut down and the oil supply terminated by the closing of the regulated fluid valve, the pressure of the oil supply will subsequently decrease upon release of the pressure in the separator and thus the regulated fluid valve can open under gravity. This will allow an immediate supply of

Abstract

Une vanne d'arret possede un piston (12) pouvant coulisser dans une enceinte (10). Un element de vanne cooperant (20) et un siege (14a) assurent la regulation de l'ecoulement de fluide entre l'orifice d'entree (13) et l'orifice de sortie (15) en reponse au mouvement du piston (12). Le piston (12) se deplace en reponse a la pression du fluide de commande appliquee sur l'orifice de commande (16). Lorsqu'il est entierement ouvert, le piston (12) et le second element de vanne (21) assurent l'etancheite entre le fluide de commande et le fluide regule. Des joints d'etancheite dynamiques ne sont pas necessaires entre le piston (12) et l'enceinte (10). La vanne est appropriee pour des constructions normalement ouvertes et des constructions normalement fermees.
