  • Patent number: 7464883
    Abstract: A valve (10) is described for use in oil injection of an oil mist (8) for lubricating/flushing cylinders in large engines and arranged with mounting means (14) for fastening in a cylinder wall (2) with a valve stem (12, 13) extending through the cylinder wall and with a nozzle outlet (6) at the inner end of the valve stem. A valve is made, the spray direction of which may be adjusted after mounting. Therefore, the valve is peculiar in that the nozzle outlet (6) is disposed in the inner valve stem part (13) which is rotatable relative to an outer valve stem part (12) . The outer valve stem part (12) is fastened to or made as an integral part of the mounting means (14).

  • Patent number: 6928975
    Abstract: There is described a dosing system for cylinder lubrication oil for large diesel motor cylinders, e.g., in marine engines. The system has a supply pipe and a return pipe provided with each their valve (3, 27), and which are connected with a central supply pump. This comprises a number of injection units that are connected with the said pipes. Each unit comprises an injection nozzle for injecting atomized cylinder lubricating oil into an associated cylinder, a piston (1) provided at a rearmost part of the nozzle rod, and a controllable motor (37) which via a screw (33) is connected with the piston (1) in order thereby to adjust the pump stroke of the piston (1). Futhermore, the system comprises a central computer for controlling the valves (3, 27) and the motor (37) so that precise control of the amount of oil and precise timing are achieved.
