Safety circuit breaker for pressurized-fluid handling installation
First Claim
1. Safety circuit breaker for pressurized fluid handling installation comprising:
- two elements, male and female, which are adapted to be fixed to ends of two portions of pipe and which male and female elements are adapted to fit axially in each other and become locked relative to one another,a sleeve mobile between a first position spaced from at least one orifice in said female element and extending radially relative to an elongated central axis of said male and female elements, said at least one orifice being adapted to provide a flow of the pressurized fluid to pass to the male element and a second position closing said at least one orifice to prevent flow of fluid to said male element, means for releasably locking said sleeve with respect to said male element when in said first position such that when said male element is moved within said female element in a direction to be disconnected therefrom, said sleeve is moved from said first position to said second position and is released from locking engagement with said male element.

Abstract
Safety circuit breaker for a pressurized fluid handling installation wherein the circuit breaker includes a male element and a female element which are adapted to be connected axially with respect to one another such that, when assembled, the male element is connected to a sleeve mounted within the female element. Movement of the male element to a position of unlocking relative to the female element causes the internal sleeve to move from a first position to a second position wherein at least one orifice within the female element is blocked to prevent fluid flow therethrough. The at least one orifice is directed radially relative to the axis of the male and female element such that pressure against the sleeve is radial and not axial. A locking of the male element relative to the female element is created by balls which are carried by a slide which is elastically urged so as to force the balls into a groove in the male element.

- 10. Safety circuit breaker for pressurized fluid handling installation, comprising two elements, male and female, which are adapted to be fixed to ends of two pipe portions and which are adapted to fit axially in each other, provoking the opening of an internal valve, the locking of the male element in the female element being effected with the aid of a plurality of balls which are mounted in a bore of a body of the female element and which are provided to engage radially in an annular groove made in an outer wall of a connector of the male element, said balls being carried by a slide, and means for elastically urging said slide, wherein said means for elastically urging said slide urge said slide towards a position in which said balls project inwardly of said slide, said slide then being in abutment against a stop limiting movement of said slide towards an inside of said female element, so that the introduction of said connector of said male element in said female element is prevented in this position.
