Abstract
A hydraulic coupling assembly having first and second connectors for making fluid connections between two hydraulic fluid lines. One of the connectors has a stationary valve assembly with a valve element moveable into and out of engagement with a valve seat. The other connector has a moveable valve assembly with a second valve element movable into and out of engagement with a valve seat. The valve assembly is movable on a plunger with respect to a connector housing. A bias mechanism such as a spring biases the plunger outward with respect to the housing. When the connectors come together, the valve tips bear against each other and are mutually retracted with respect to the respective valve seats. The bias mechanism acting on the plunger in the second connector maintains the valve elements in contact with one another and in a deflected state permitting hydraulic fluid passage through the fluid passage opened between the connectors.
