DOSING SYSTEM FOR LUBRICATING OIL FOR LARGE DIESEL ENGINES AND METHOD FOR DOSING CYLINDER LUBRICATING OIL TO LARGE DIESEL ENGINE CYLINDERS

摘要

for example ship engines (32) in the heavy-duty diesel engine cylinder (5) for the cylinder lubricating oils administration system is illustrated, the system includes, for example, a central power station (1) of the central lubrication oil supply; Supply lines from / to the lubricating oil supply for circulating the lubricating oil 31 and the return line 33; Branch lines (7, 15, 16) is connected with the supply and return line through the nozzle hole 20 through the associated cylinder (5) in the cylinder lubricating oil 21 is applied to the injection, the at least one engine (32 a number of injectors (6) corresponding to the number of cylinders in a); Injector open / close valve unit provided in (6) and the branch line between the supply and return lines 15 and 16 (3) of the; And a respective open / close valve unit (3) control unit 25 for controlling the. In order to achieve a flexible central control, and precise control of the timing of the injection amount of oil, the open / close valve unit (3) are spring in the injector-biased closure member 18 in the supply line to the first chamber 22 of the rear ( 31) and the return line 33 and the first inlet that can be connected to each of (P) and the system is designed to have a first outlet (R). The injector (6) is a closed member of the injector (18) has a second chamber (24) above, the second chamber is a branch line connecting the second chamber 24 of the injector and the supply line 31 7 and It is connected. The control unit 25 is connected with at least the open / close valve unit (3). ;
