燃機関のシリンダ注油装置。 The piston rod of the piston that fits into the cylinder reciprocates in a straight line by a crosshead that is provided at the end of the piston rod and moves along a guide, and the reciprocating movement of the piston is applied to the crankshaft via the connecting rod and the crank as a rotational force. The cylinder lubricating device for a crosshead internal combustion engine includes a cylindrical hole formed concentrically in the piston rod, a weight fitted into the cylindrical hole so as to be slidable in the axial direction, and an oil pump having a plunger that is provided in the piston and pumps lubricating oil by the collision force of the weight; an oil supply path formed in the piston rod; It is characterized by comprising an oil passage communicating with the head side chamber of the plunger, and a lubricating oil passage communicating with the oil passage via a delivery side check valve and communicating with a piston ring groove provided on the outer periphery of the piston. Cylinder lubrication system for crosshead internal combustion engines.
