Abstract
A hose-coupler made up of a just one component having a main housing section with a female end and a male end. The second female end of the coupler is formed with interior threads, for receiving therein a portion of the male end of the second hose. The main housing section has a compressible portion adjacent to the first male end thereof all the way to the end of the female end. In order to compress the clamping jaws, there is provided a slidable outer housing. The male end is sealed in the female end of the coupler by a biased piston-member that forces a sealing washer against the male end by means of the pressurized fluid volume in the interior of the coupler. Two embodiments are disclosed: A first one that allows the coupler to be disconnected from the male end of a hose only after the water pressure has been turned off; and a second embodiment that allows the coupler to be disconnected from the male end of a hose also while the water pressure is still present. In the second embodiment, a check valve prevents the back-flow of back-pressurized fluid through the coupler after the coupler has been disconnected from a male end of a component.
