ABSTRACT:
A combination one-way check valve and coupler assembly is shown for use in bleeding air from the wheel brake cylinders of automobiles and the like. This one-way check valve is adapted to be attached to a standard bleeder valve that is assembled to each wheel brake cylinder. One-way check valves have been used for this purpose before, but the present invention incorporates a coupler means between the one-way check valve and a standard bleeder valve that is positive and reliable in operation. This coupler means is in the form of a threaded nut that is threaded onto the inlet end of the valve body of the one-way check valve. The outermost end of this threaded nut is slotted from one side to create a spaced, three-sided flange that is capable of slipping over and behind the nipple of a standard bleeder valve so that when the nut is tigntened onto the check valve body, the nipple will be drawn into sealing engagement with a recessed valve seat of the inlet end of the check valve body.
