Abstract
A rigid, multiple-passage, quick-disconnect coupling in which valves of a supply section of the assembly are moved to mechanically open valves in a receiver section for enabling pressurization of telescopic cylinder sections. Energization of the innermost cylinder section automatically actuates the valves for enabling pressurization of the remaining cylinder sections. The coupling sections have opposed valve surfaces substantially flush with the surrounding surfaces of the coupling sections.
