Abstract
Vacuum safety valve mechanism, characterized in that it opens when the fluid pressure in a high pressure fluid supply line drops to a value only slightly lower than that of the fluid in a low pressure fluid return line, with in order to prevent a further pressure drop in the feed line and comprising elements that make up a body having: a feed conduit that provides a part of the high pressure fluid feed line; a return duct providing a portion of the low pressure fluid return line, and having a portion contiguous with a portion of the supply duct; a shunt that communicates said contiguous portions of the supply and return ducts; and an annular valve seat in said portion of the return conduit constituted by a surface adjacent to the wall that is closest to the supply conduit; wherein the surface constituting the seat is not oriented towards the feed conduit, is coaxial with the branch and surrounds its adjacent end.
