Zusammenfassung:PURPOSE:To reduce the vibration of a plunger so as to stand continuous driving for many hours by controlling the piston motion of the plunger by a spring with one end thereof fixed to a cross head and with the other end thereof fixed to a cross head bearing part. CONSTITUTION:Liquid is fed by the piston motion of a plunger 6 jointed to a cross head 3 through a cam follower 2 in contact with the peripheral edge part of a deformed cam 1. In this case, mechanism for controlling the piston motion of the plunger 6 by a spring 7 with one end thereof fixed to the cross head 3 and with the other end thereof fixed to a cross head bearing part 4 is provided between the cross head bearing parts 4 for supporting the cross head 3 at least at two places. The torsion and micro vibration of the plunger 6 with a system of converting rotary motion into piston motion are thereby reduced so as to stand continuous driving for many hours.
