<p>PURPOSE:To miniaturize a plunger pump and simplify its structure while the decelerating function is given to the plunger pump. CONSTITUTION:A plunger 36 is guided in the axial direction by a guide 42, and energized toward a driving shaft 18 by a compressive spring 54. A driving gear 56 is integratedly mounted on the driving shaft in the rotational direction, and engaged with a driven gear 58. The driven gear 58 is provided with a through hole with a keyway in an off-centered manner relative to the center of the shape, and a cross pin 60 is rotatably and pivotably supported by a branched part of a cross head 40 of the plunger 36 at each end part, and integratedly rotated together with the driven gear 58 through the through hole with the keyway.</p> |
