ABSTRACT:
A fluid coupler comprises a ball valve a through hole provided between a female coupler body and a valve holding casing connected to the female coupler body and surrounding the ball. The ball valve has a first flat sliding surface formed on a spherical outer surface of the ball valve which extends in a direction normal to a rotational axis of the ball valve, and a flat stop surface raised from the first flat sliding surface and reaching said spherical outer surface of said ball valve, the first flat sliding surface and the flat stop surface together defining a recess. The valve holding casing has an alignment portion formed on and raised from an interior surface thereof. The alignment portion has a second flat sliding surface slidably engaged with said first flat sliding surface. The flat stop surface is adapted to engage with the alignment portion to limit the rotational movement of the ball valve.
