  • Patent number: 8602167
    Abstract: There is described a hydraulic lubricating apparatus (252) for dosing cylinder lubricating oil, including a housing which via one or more valves (220) is connected to a source for supplying hydraulic oil (262) and cylinder lubricating oil (not shown), a number of hydraulic cylinders each having a hydraulic piston (6) and which may be pressurized by hydraulic oil. Furthermore, there are a number of injection units (251) corresponding to a multiple of the cylinder (250) number in the engine, and which are connected with each their dosing cylinder by a dosing piston (21). Also, there is provided a distributor plate (7) which at one side is in contact with the dosing pistons (21) and which at its other side is in contact with the hydraulic pistons (6) for displacing the distributor plate for actuating the dosing pistons.

  • Patent number: 8210317
    Abstract: There is disclosed a method and a hydraulic lubricating apparatus for dosing cylinder lubricating oil. The dosing system includes a supply line and a return line connected with the lubricating apparatus via each one or more valves for supplying hydraulic oil, a central hydraulic oil feed pump connected with hydraulic cylinders, each having a hydraulic piston and which may be subjected to pressure by hydraulic oil via the supply line, a number of injection units corresponding to a multiple of the cylinder number in the engine and which are connected with each their dosing cylinder with a dosing piston and a supply line for cylinder lubricating oil.

  • Patent number: 7681548
    Abstract: There is described a method and an installation for lubricating cylinder surfaces 6 in large diesel engines. The installation includes a lubricating apparatus 3 with a number of piston pumps 4 which via connecting lines 5 are connected with lubricating points 6 in the cylinder walls 7. In order to enable electronically controlled regulation of the lubricating oil portion, there is provided an electronic control unit 9 which is connected with a flow regulator 8. The flow regulator includes redirecting valves 12 which are inserted in connecting lines 5 between the lubricating apparatus 3 and the lubricating points 6.
