Abstract (en)

[origin: WO9102159A1] An air pump (10) particularly suitable for use with bicycles includes a first elongated tube (18) to form a pump chamber and housing, a second elongated tube (20) coupled with a piston in the first tube to reciprocate the piston within the pump chamber. A flexible hose (44) extends from the piston and through the second tube and has at its exposed end an air valve coupling (50). The first and second tubes are releasably secured to permit use of the pump as a seat post. The pump includes a first valve on the outside of the piston between atmosphere and a closed end of the pump chamber and a second valve inside the piston between the closed end of the chamber and the flexible hose. The first valve is configured to provide greater seal effect as pressure builds in the closed end of the pump chamber.
