20080247884 | PORTABLE AIR PUMP - A portable air pump includes a tubular body, a barrel, a piston mechanism, a head, and a dispensing head. Tubular body has upper cover having air inlet holes and sealed bottom cover. Barrel has air passage running through along its axis direction. Piston, having center hole and through hole, and check valve is in between second end of the barrel and piston. As tubular body is moved in relation to barrel away from the head, air is flown into tubular body through air inlet holes and to the bottom of tubular body through the through hole. Air can be prevented from flowing out from the center hole using check valve disc. As the tubular body is moved in relation to the barrel towards the head, air on the bottom of tubular body is flown into air passage of the barrel through center hole, and out from the head and the dispensing head. | 10-09-2008 |
20080271789 | Pump Connector For Presta Valve - Pump connector for Presta valve is disclosed in which one end of a pump connector valve seal is formed with a hollow chamber, and is disposed inside a space of a cap having a channel. The hollow chamber is assembled with a valve seal insert which includes a through hole. The second end of the through hole is formed with an inner edge corresponding to the shape of the shoulder section of the Presta valve. An end cap is assembled with the cap for preventing the pump connector valve seal from separating from the cap. Accordingly, the Presta valve can be screwed together with a first internal thread of the cap, and at the same time the shoulder section of the Presta valve is tightly fitted to the inner edge of the valve seal insert for direct inflation. | 11-06-2008 |
20100019491 | DISPENSING HEAD FOR AIR PUMP - A dispensing head for an air pump includes a sleeve connected to the air pump and a chamber is defined in an end of the sleeve. The end having the chamber of the sleeve is received in a housing and a mount piece is securely received in the housing. A first seal ring is mounted to the mount piece and in contact with an inner periphery of the chamber. The mount piece includes a plurality of inner threads defined axially in a central passage in the mount piece, so that the threaded section of a French valve is threadedly connected to the inner threads. A second groove is defined in the mount piece and a second seal ring is engaged with the second groove. The second seal ring is mounted to a neck of the French valve. | 01-28-2010 |

20110123262 | INFLATION NOZZLE CAPABLE OF CONNECTING WITH TWO TYPES OF TIRE VALVES - An inflation nozzle includes a first part having a first threaded passage defined centrally therethrough and a connection ring is threadedly connected to a first end of the first part. An insertion is formed on a second end of the first part and is engaged with a first chamber of a central member which is received in a second part. The central member is connected with a tire pump. The first passage is sized to be connected with a French valve and the connection ring is sized to be connected with an American valve. | 05-26-2011 |
20110155260 | ROTATABLE DUAL HEAD INFLATION DEVICE - An inflation device includes a central tube, a first mounting unit mounted onto an outside of a reception end of the central tube and a second unit connected to a connection portion on the other end of the central tube. The first mounting unit includes a first casing and an end cap, and the reception end includes a valve mouth and a core tube received therein. The second mounting unit includes inner threads that are connected with the connection portion. A groove is defined in the second mounting unit and an O-ring is engaged with the groove. The first and second mounting units can be connected with an American style tire valve and a French style tire valve, respectively. The first and second mounting units each have outer threads with the same diameter so as to be connected with a tire pump. | 06-30-2011 |
