SLURRY FORCE-FEED APPARATUS

Japanese Patent JP3860951

B2

PROBLEM TO BE SOLVED: To provide a slurry force feed apparatus which enhances the sealing performance of a contact portion of a liner ring connected to a cylinder with a plate arranged in an apparatus main body.
SOLUTION: The slurry force-feed apparatus which is comprised of the apparatus main body, pairs of piston-cylinder mechanisms, and a connecting pipe. The apparatus main body has a wall portion in which a plurality of connection holes opening toward an internal space from which slurry is supplied, are formed. The piston-cylinder mechanisms each consist of a cylinder connected to each connection hole and a piston carrying out sucking operation and discharging operation. The connecting pipe is selectively connected to one of the connection holes formed in the wall portion of the apparatus main body, to thereby receive and feed the slurry discharged from the piston-cylinder mechanism. The apparatus further includes the plate having a hole is fitted in a recess surrounding openings of the connection holes formed in the wall internal surface of the apparatus main body, and the liner ring which is inserted in the interior of each connection hole. Further, the plate and each liner ring are combined with each other such that the contact portion between a bottom surface of the recess and a side surface of the plate is sealed with a surface along an axial direction from the interior of the connection hole.
