Abstract
An improved quick-disconnect connector assembly for connecting hoses, having a female element for connection to a first hose and a male element for connection to a second hose. The female element has an axial bore having a sealing mechanism for sealably receiving a tubular portion of the male element. The male element further comprises resettable valve including a coil spring that extends into the bore in the female element and is retained therein by a U-shaped clip. The spring is sized to hold the male element axially within the sealing mechanism up to a desired inline pressure. When the pressure limit is exceeded, the male element spring is extended until the seal is broken, relieving the overpressure condition. When the un-sealing force has been relieved, the extended spring biases the male element back into sealing relationship with the female element, thereby automatically resetting the relief valve.
