Abstract
A low spill anti-check fluid coupling for pressurized fluid systems is disclosed. The coupling includes a female part and a male part. The female part has a body member and a sleeve mounted for axial movement within said body member. A spring biased female valve is positioned within the body member. A handle mounted for rotation on said body member is operatively connected to the sleeve for opening said female valve to initiate fluid flow through the coupling. An anti-check spring is operatively connected to the female valve for retaining said female valve is an open position when the fluid coupling is in an open fluid flow condition.
