TANK INTEGRATED TYPE PUMP DEVICE AND RESERVOIR TANK USED FOR THE DEVICE

摘要

PROBLEM TO BE SOLVED: To improve space efficiency of a tank integrated type pump device.SOLUTION: A suction plug 32 connected to a suction plug connection hole 11 on the side of a pump device 2 is provided between a lowermost part 30 of a tank body 24 of a reservoir tank 3 and an oil level V. A pressure chamber 34a is provided in a tank body 24 perpendicularly below an opening part 32a of the suction plug 32 on the side of the tank body 24. Consequently, a space of the tank body 24 which is perpendicularly below the opening part 32a of the suction plug, what is called a dead space can be effectively used to improve space efficiency of a tank integrated type pump device 1.
