Abstract
PURPOSE: To have a simple and sure piston lubrication which requires no loss of lubricant by installing an oil supply pump, which performs pumping action in utilizing piston's inertia at the time of reciprocating motion, at the skirt part of the piston.
CONSTITUTION: A pump house 4 for an oil supply pump 3 is formed inside the skirt part 2a of a piston 2, and an opening at the bottom of this pump house 4 is blocked with a lid 5, near which an air hole 6 is excavated. In the pump house 4, a piston peace 7 having a certain specific weight is inserted in such a manner as moving vertically owing to piston's inertia at the time of its reciprocating motion. A port 8 to serve both for suction and discharge is opened at a point within a range from the top of the pump house 4 to the piston skirt 2a while an oil hole 9 is opened at the point specified as mating with the port 8 on the cylinder 1 side. This oil hole 9 is led to a pipe 10 in communication with the oil contained in an oil pan.
