ABSTRACT:
A hose coupling includes an element having one end coupled to a pressurized liquid source and the other end having a valve seat, and a barrel secured to the other end of the element. A stop member is secured between the barrel and the element. A valve member is slidably engaged in the element and has a valve stem slidably engaged in an aperture. The valve stem has a head for engaging with the valve member and biased to engage with the valve member. An insert is slidably engaged in the barrel and has a pusher for disengaging the head from the valve member. A spring may bias the insert away from the stop member, and a connector may engage into the barrel for forcing the insert to disengage the head from the valve member and for allowing the pressurized liquid to flow through the hose coupling.
