Abstract:
1. A quick disconnect valve assembly, comprising: first and second valve elements that each include a housing defining a fluid passageway having a seat configured for sealing engagement with a respective plunger, the first and second valve elements further including respective resilient elements arranged so that when the first and second valve elements are engaged, each resilient element biases a respective plunger into engagement with the other plunger so that the plungers reside in an equilibrium position where the fluid passageways are in fluid communication with each other; a coupling having first and second halves, the first housing being attached to the first half of the coupling, and the second half of the coupling being configured to releasably engage the second housing; a breakaway collar that releasably joins the first and second halves of the coupling together; and a handle at least indirectly attached to the coupling.
