Abstract
A hand pump includes a receptacle extended upwardly from a base, a housing attached to the base and having a port connected to a pressure gauge, a hose coupled to the housing and having a nozzle for inflating tires or objects, a sleeve slidably engaged onto the receptacle, and a check valve engaged in the receptacle for controlling the pressurized air to flow only from the sleeve into the receptacle and for preventing the pressurized air from flowing backward from the receptacle into the sleeve in order to generate the pressurized air in the receptacle, and for allowing the receptacle to store the pressurized air when required. A control valve device controls the pressurized air to flow out of the housing.
