<p>PROBLEM TO BE SOLVED: To provide a plunger pump which can be easily machined and reduced in its manufacturing cost. SOLUTION: A plunger 20 is slidably accommodated in a cylinder 5 formed in a housing 1. In addition, a rotary shaft 3 and a rotary cam 26 which is attached to the rotary shaft 3 and comes into contact with the plunger 20 on an outer peripheral cam face 26a to reciprocatively drive the plunger 20 are provided. The rotary cam 26 is constructed so that the axial center Ya of the outer peripheral cam face 26a coming into contact with the plunger 20 is eccentric to the axial center Yb of an inner peripheral attaching face 26b attached to the rotary shaft 3.</p> |
