    摘要: In a mixing pump device (1), during an suctioning step a stepping motor (12) rotates in a first direction, so that during this time, a plurality of fluids can be drawn in prescribed proportions into a pump chamber (2), by sequentially opening and closing active valves (5a, 5b) situated in inflow passages (3a, 3b) while active valves (6a, 6b) situated in outflow passages (4a, 4b) are in a closed state. During the discharging step the stepping motor (12) rotates in a second direction, so that during this time, a mixed fluid can be discharged from the pump chamber (2) simply by sequentially opening the active valves (6a, 6b) situated in the outflow passages (4a, 4b), while the active valves (5a, 5b) situated in the inflow passages (3a, 3b) are in a closed state. It is possible thereby to achieve a mixing pump device capable of mixing a plurality of fluids in prescribed proportions, without detecting the operating stage of the pump.

    摘要: 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).

    摘要: A multi-channel pump includes a pump chamber, an inflow passage connected to the pump chamber, two or more outflow passages connected to the pump chamber, outflow side active valves provided so as to correspond to the outflow passages, and a movable body reciprocated to change a volumetric capacity of the pump chamber. The movable body may be a piston reciprocated within a cylinder that is connected to the pump chamber. A control method for a multi-channel pump includes an initial discharge step between a suction step and a discharge step. The multi-channel pump may be preferably utilized in a fuel cell.

    摘要: A metering pump device capable of performing a fixed amount of discharge with a high accuracy even if a pressure difference occurs between outflow side valves. In the metering pump device, two reciprocating pump devices are used. The end and start of the discharge period of one reciprocating pump device are overlapped with the start and end of the discharge period of the other reciprocating pump device. After the inhalation operation and before the discharge period, both the inflow side valves and the outflow side valves are closed to perform a correction operation for eliminating the pressure difference by increasing or decreasing the internal volumes of the pump chambers.
