Patent ID: 8720474

Claim:
An air valve connecting device comprising: a housing including a chamber formed therein, and including an inlet mouth for receiving a pressurized air, a gasket engaged into said chamber of said housing and including a bore formed therein for engaging with an inflation valve, a casing slidably engaged in said chamber of said housing and engaged with said gasket for selectively compressing said gasket to grasp and retain the inflation valve to said housing, and said casing including a compartment formed therein and communicative with said bore of said gasket, said casing including a swelling extended therefrom and having a passage formed in said swelling and communicative with said compartment of said casing, a valve piece slidably engaged in said compartment of said casing and extendible into said bore of said gasket for engaging with the inflation valve, and said valve piece being engageble with said casing and for selectively blocking said compartment of said casing, a first spring biasing member for biasing said valve piece to engage with said casing, an actuator slidably engaged in said chamber of said housing and engageble with said casing for selectively forcing said casing to compress said gasket to grasp and retain the inflation valve to said housing, and said actuator including a peripheral pathway communicative with said inlet mouth of said housing for receiving the pressurized air from said inlet mouth, and including an aperture formed therein, and including a channel formed therein and communicative with said aperture and said peripheral pathway for allowing the pressurized air from said inlet mouth of said housing to flow into said peripheral pathway and said aperture of said actuator, and including a valve seat extended into said aperture of said actuator, a valve member engageble with said swelling of said casing and disposed in said aperture of said actuator and movable to engage with said valve seat and to block said aperture of said actuator by the pressurized air, and a handle pivotally attached to said housing and including a cam member for engaging with said actuator and for selectively forcing said actuator to force said casing to compress said gasket and to grasp and retain the inflation valve to said housing.
