Abstract
The present invention relates to a coaxial quick coupling suitable for being employed in very high pressure applications in the field of emergency tools, such as shears, retractors, cylinder lifters and the like, and/or in the construction field. The coupling according to the present invention is characterized in that it has a high standardization of the internal components, different components being used both in the male coupling and in the female coupling, and in that it has a greater structural and constructional simplicity, also having few points of elastomeric sealing, which results in longer duration and greater reliability of the coupling itself.
Claims9
A coaxial quick coupling of the type comprising a male component and a female component wherein at least two coaxial paths are identified, one for the high pressure line and one for the low pressure line, t wherein each of said male and female components comprises a component for channelling the low pressure flow and a movable equipment on the high pressure line comprising an axial, metal seal valve kept in place by elastic means acting between said valve (6) and said component, said elements on the high pressure line of the male component being identical to the corresponding elements on the high pressure line of the female element, and in that said female component further comprises a slider which, with the coupling disconnected, is kept in closed position against a fixed element by a spring thus closing the low pressure line, and which is shifted by the male element against the spring when the coupling is connected, thus opening the low pressure line.
A coaxial quick coupling according to the preceding claim, wherein said axial valve creates a metal sealing for the high pressure fluid in said female component, on a body outside said valve and coaxial thereto.
