Abstract
A coupling assembly includes a nipple component and a coupler component that are connectable to each other to form a fluid flow pathway through the coupling assembly. The nipple component includes a nipple body that defines a chamber that receives a first valve and a second valve that are moveable within the chamber, and the first valve and the second valve are spring biased against each other by a spring loaded plunger of the first valve, and a second valve spring that biases the second valve in the closed position. During a connection operation and/or a disconnection operation, a balance of forces including the spring bias, in combination with system pressure, maintains the second valve in a closed position, thereby isolating the fluid flow from an area of the chamber in which components of the first valve reside, including isolating an interface seal from fluid flow.
