Abstract
A fluid pressure feeding device includes: a follower plate that is inserted into a tank, that applies a pressing force to a fluid, and that has an opening for pumping up the fluid from an inside of the tank; a pump having a primer plate configured to exhibit reciprocating movement to pump up the fluid in the tank into a pump internal space; and a position control unit configured to control a position of the primer plate within a range of the reciprocating movement. An outer shape of the primer plate substantially matches a shape of the opening of the follower plate, and the position control unit is configured such that the primer plate is positioned in the opening of the follower plate when the follower plate is taken out from the tank.
