Abstract

PURPOSE: To conduct suction and discharge actions positively by a method wherein a piston pressure-sending a lubricant such as grease is supplied with a change- over valve function, and a change-over valve is actuated forcibly by mechanical power.
CONSTITUTION: A pump includes a pilot piston 3 directly reciprocated in the axial direction by means of a driving mechanism A and a main piston 2 moved by differential pressure and the driving mechanism A. The width of a cut piece 13 of the main piston 2 is made larger than a diameter of a sliding piece 10, a loose clearance L in the axial direction is formed to the piston 2 and a differential phenomenon is generated to the both pistons 2, 3 by the slack. In a process of the phenomenon, piston chambers 15, 16 and passages 17, 18, 22 are changed over, and the pistons 2, 3 serve both as functions original to pistons which suck and discharge a lubricant and the functions of change-over valves as suction and discharge valves. The biting of particulates is prevented because the piston 2 is made larger than the piston 3.
