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.

Abstract: A fluid pressure-feed device includes a main tank and a sub tank. The sub tank is connected integrally with an upper portion of a main follower plate that applies pressurizing force to a urethane adhesive inside the main tank. A drum pump is provided in an upper portion of a sub follower plate provided in the sub tank. While the urethane adhesive is flowing into the sub tank from the main tank, the urethane adhesive is fed under pressure from the sub tank to a fluid passage by actuation of the drum pump. While the main tank is being replaced, the urethane adhesive inside the sub tank is fed under pressure to the fluid passage by the drum pump.
