Abstract
Fluid couplings described herein are designed to prevent spillage of fluid when connecting and disconnecting the couplings. In some embodiments, the fluid couplings described herein include internal valve components. In some example embodiments, the internal valve components include two springs that are arranged to exert their spring forces in parallel with each other to bias a valve component to a normally closed position. Some embodiments include a single spring. In particular embodiments, components of the fluid couplings and fluid flow paths of the fluid couplings have oblong transverse cross-sectional shapes.
