Abstract:
1. Lubricating apparatus in an engine for dosing engine cylinders with lubricating oil, the lubricating apparatus comprising: a housing; a source of cylinder lubricating oil; one or more valves connected with the source for supplying cylinder lubricating oil; a number of hydraulic cylinders that each have a hydraulic piston and which are pressurised by hydraulic oil; a number of lubricating oil injection units corresponding to a multiple of the number of cylinders in the engine, and in which each lubricating oil injection unit is connected with each their dosing cylinder by a lubricating oil dosing piston; each engine cylinder having a plurality of lubricating oil dosing pistons; and a distributor plate which at one side is in contact with the dosing pistons and which at its other side is in contact with the hydraulic pistons for displacing the distributor plate for actuating the dosing pistons, wherein the hydraulic pistons that displace the distributor plate are provided in groups of hydraulic pistons, and wherein each group of hydraulic pistons is adapted for independent displacement of the distributor plate for actuating the dosing pistons, and that each group of hydraulic pistons has an individual stroke, whereby controlling strokes of groups of hydraulic pistons controls differential actuating of the dosing pistons.
