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.

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.
摘要翻译：在混合泵装置（1）中，在抽吸步骤期间，步进电动机（12）沿第一方向旋转，使得在此期间，可以将规定比例的多种流体抽吸到泵室（2）中，通过依次打开和关闭位于流入通道（3a，3b）中的主动阀（5a，5b），同时位于流出通道（4a，4b）中的主动阀（6a，6b）处于关闭状态。在排出步骤期间，步进马达（12）沿第二方向转动，从而在这段时间内，只要依次打开位于该泵室（2）内的主动阀（6a，6b）即可将混合流体从泵室（2）排出而流入通路（3a，3b）中的主动阀（5a，5b）处于关闭状态。因此，可以实现能够以规定比例混合多种流体而不检测泵的操作阶段的混合泵装置。

摘要： During switchover from a suctioning step to a discharging step, a mixing pump (1) carries out a correcting step for displacing a displacing member (17) in the direction for reducing an internal volume of a pump chamber (2); and during switchover from the discharging step to the suctioning step, the pump carries out a correcting step for displacing a displacing member (17) in the direction for increasing the internal volume of the pump chamber (2). In the correcting step, intake ports (30a, 30b), and discharging ports (40a, 40b) of the pump chamber (2) are closed, and the displacing member (17) undergoes displacement for increasing or reducing the internal volume of the pump chamber (2) in a hermetic state. Instability caused by backlash of the displacing member (17) drive system can be eliminated, and a pressure difference between the pump chamber (2) interior and the fluid intake end or the fluid discharge end can be eliminated. It is therefore possible to eliminate or reduce variability in the amount of fluid intake or amount of fluid discharge when switching between the suctioning step and the discharging step.
摘要翻译：在从抽吸步骤切换到排出步骤期间，混合泵（1）执行校正步骤，用于使换位构件（17）沿减小泵室（2）的内部容积的方向移位; 并且在从排出步骤切换到抽吸步骤期间，泵执行校正步骤，用于沿着用于增加泵室（2）的内部容积的方向移位位移构件（17）。在校正步骤中，泵室（2）的进气口（30a，30b）和排出口（40a，40b）被关闭，并且移动构件（17）经历位移以增加或减小泵的内部容积室（2）处于密封状态。可以消除由位移构件（17）驱动系统的反冲引起的不稳定性，并且可以消除泵室（2）内部与流体进入端或流体排出端之间的压力差。因此，在抽吸步骤和排出步骤之间切换时，可以消除或减少流体吸入量或流体排放量的变化。

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).
