ABSTRACT:
The invention is a coupling which includes male and female portions thereof. The male portion usually has pressure applied to it due to heat build up from the environment. The male portion can be and usually is attached to a farm implement. Left in a field in the sun, pressure builds in the male portion while it is disconnected from the female portion. The female portion of the coupling enables the connection of the male portion without spilling any fluid from either the male or the female portions. This is accomplished by the simultaneous engagement of the body of the male and the male valve with an intermediate member of the female portion and the female valve of the female portion such that the female valve and the intermediate member move together into a sealed relationship with the male components. When the supply side female portion is pressurized by a pump the female valve forces the female and male valves to their open positions and allows flow between the female and male portions of the coupling.
