Patent

CA 2674796

A tubular fluid pump is provided. The pump includes a chamber for receiving and discharging fluid, and a squeezing mechanism for pumping fluid through the chamber. The chamber has a first end with a first opening, a second end with a second opening, and a length of resilient tubular material extending between the first and second openings. One-way valves disposed at the openings cooperate to permit fluid to pass through the chamber in only one axial direction. The squeezing mechanism includes a substantially rigid base and a substantially rigid displaceable actuator. The tubular material is mounted on the base of the squeezing mechanism, and the actuator is aligned to alternately squeeze the tubular material against the base to pump fluid out of the chamber, and release the tubular material from the base to draw fluid into the chamber. A steam appliance incorporating a one-way tubular pump is also provided.
