Abstract
A quick coupling assembly includes a first coupling element (10) and a second coupling element (50) that is inserted into the first coupling element. The first coupling element has a coupling body (12) and a valve (20), which define a volume displacement passage. When the second coupling element (50) is inserted, the second coupling element mechanically acts on the valve (20) to expel contaminants from the quick coupling assembly via the volume displacement passage. The valve includes a poppet (22) and a biasing spring (24), and the volume displacement passage includes a leak path (66) defined between the coupling body and the poppet. The poppet has an inward contour (68) that is spaced apart from the coupling body to define the leak path. The poppet has a widened portion (70) that provides a sealing surface when the assembly is fully coupled. The second coupling element (50) mechanically acts on the poppet (22) during insertion to expel the contaminants via the volume displacement passage.
