Summary:PROBLEM TO BE SOLVED: To prevent pressurized liquid from staying in a pump chamber and enable to efficiently discharge the same from a delivery passage. SOLUTION: This pump is provided with a pump casing 25 and an impeller 42. The pump casing includes a pump chamber 39, a suction passage 55 leading liquid to the pump chamber and a delivery passage 56 discharging liquid from the pump chamber. The impeller is stored in the pump chamber, sucks liquid into the pump chamber from the suction passage by rotation thereof, and pushes the sucked liquid out of the pump chamber to the delivery passage. The delivery passage includes a first opening end 58a opening in the pump chamber and a second opening end 58b positioning in the downstream of the first opening end. The first opening end has larger opening area then the second opening end. COPYRIGHT: (C)2006,JPO&NCIPI
