Title:
MIXING PUMP DEVICE AND FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2007/135779
Kind Code:
A1
Abstract:
A mixing pump device (1) used for fuel cells etc. has two inflow paths (51, 52),
inflow side active valves (21, 22) arranged at the two inflow paths (51, 52), respectively,
a pump chamber (11) into which liquids flow via each of two inflow paths (51, 52),
four outflow paths (61, 62, 63, 64) for allowing a liquid mixed in the pump chamber
(11) to flow out, and outflow side active valves (31, 32, 33, 34) arranged at the
four outflow paths (61, 62, 63, 64), respectively. Further, a chamber (82) is
formed between the pump chamber (11) and a branch point (80) at which the outflow
paths (61, 62, 63, 64) branch off. The construction prevents a variation in the
concentration of the liquid allowed to flow out of the outflow paths (61, 62, 63,
64) after the mixing in the pump chamber (11).
