Abstract
A coupling that is useable on farm implements is disclosed. A metal to metal vent valve is employed in the female half of the coupling which constantly vents the supply port to the vent port when the female half is disconnected or partially disconnected from the male half. Steps in the bore of the female body permit easier disconnection because the ball valve is not depressed thus lowering disconnection faces. When the male half is being coupled with the female half the female half is vented thus making coupling easy.
