Filed: 2000-09-22
Abstract: PROBLEM TO BE SOLVED: To reduce pump vibration in a pump provided with a reciprocating piston. SOLUTION: An eccentric shaft 41 of a crank shaft 40 is inserted into a hole part 14 formed at a center part of the piston 13, and the piston 13 is reciprocated as the crank shaft 40 is rotated.
