QUICK COUPLING WITH LOWER SEPARATION FORCE

摘要

A coupler (200) for a fluid coupling (10) is provided that includes a valve housing (210) and a valve member (230) with an inclined seal (260). The valve housing (210) has a through-passage (212) and a tapered valve seat (216) surrounding the through-passage (212). The valve member (230) is moveable along an axis (50) in the valve housing (210) between a closed position engaged with the valve seat (216) to block fluid flow through the through-passage (212) and an open position spaced from the valve seat (216) to allow fluid flow through the through-passage (212). The inclined seal (260) has a sealing surface (261) for engaging the valve seat (216) when the valve member (230) is in the closed position, which reduces the sealing diameter of the valve member (230) and enables a lower separation force for improved connection of the coupler (200) under pressure. The configuration of the valve member (230) with the inclined seal (260) may also improve flow performance and the durability of the valve member components.
