<P>PROBLEM TO BE SOLVED: To provide a fluid discharge pump having a fluid leakage prevention part provided in somewhere other than a pump section, simple in structure, easy in replacement, inspection and the like and capable of preventing fluid leakage. <P>SOLUTION: The fluid discharge pump has a vessel body for receiving fluid and a communication path performing reciprocation comprised of outward motion for moving toward the vessel body and return motion for moving away from the vessel body so as to be able to discharge the fluid. The fluid discharged pump is characterized in that it has a feed flow path communicating with the communication path and a piston capable of performing reciprocation in the suction flow path, which is comprised of outward motion for approaching the communication path and return motion for moving away from the communication path, and the piston comprises the fluid leakage prevention part which can move outward in the feed flow path with the outward motion of the communication path and can return in the feed flow path with the return motion of the communication path. <P>COPYRIGHT: (C)2008,JPO&INPIT |
