Abstract
A nipple characterized by an integral crossbar actuator and check valve. When a mating coupler at atmospheric pressure is connected to the nipple, the crossbar actuator functions to open a poppet valve in the mating coupler independently of the check valve. With the coupler fully connected to the nipple, pressurized media is supplied to the coupler to commence media transfer. When the pressure in the coupler exceeds the pressure behind the nipple's check valve, the check valve will open and the transfer of media will occur. Conversely, the check valve will close and prevent any further transfer of media when the supply to the coupler is ceased and the coupler is vented. The coupler can then be disconnected from the pressurized nipple. The nipple and coupler form a coupling system, and the nipple may be used to retrofit existing systems wherein valved nipples and check valves are used on a pressure side of the system.
