    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).

    Abstract: There is described a dosing system for cylinder lubrication oil for large diesel engine cylinders (5), e.g. in marine engines (32), and including: a central lubricating oil supply, e.g. a central pump station (1);a supply line (31) and a return line (33) to/from the lubricating oil supply for circulating the lubricating oil;a number of injectors (6) corresponding to the number of cylinders in the engine or a multiple thereof, and which are adapted to inject cylinder lubricating oil into an associated cylinder via a nozzle aperture (20), and which via branch lines (7, 15, 16) are connected with the supply and return lines;opening/closing valve units (3) provided in the branch lines (15, 16) between the injectors (6) and the supply and return lines; and a control unit(25) controlling each opening/closing valve unit (3). In order to achieve a flexible central control of injected amount of oil and precise control of timing, the system is designed such that the opening/closing valve units (3) have a first inlet (P) and a first outlet (R) which may connect a first chamber (22) behind a spring-biased closing member (18) in the injectors with the supply line (31) and the return line (33), respectively. The injector (6) further has a second chamber (24) in front of the closing member (18) of the injector, where the second chamber is connected with a branch line (7) connecting the second chamber (24) of the injector with the supply line (31).The control unit (25) is at least connected with the opening/closing valve units (3).

    Abstract: There is described an injection nozzle for use in injecting lubricating oil into cylinders in large engines. The nozzle is adapted for fastening in a cylinder wall with a nozzle rod extending through the cylinder wall and with a nozzle outlet at the inner end of the nozzle rod. The nozzle rod includes a cylindrical valve seat boring with a displaceable valve body having a cylindrical sealing face which interacts with the cylindrical valve seat boring of the nozzle rod, the valve body biased by a spring for effective closing of the valve. The valve body is formed by a cylindrical rod having a turned recess in the cylindrical sealing face of the valve body. The turned recess is arranged at the inner end of the valve body with parts of the cylindrical sealing face of the valve body at each side of the turned recess. The turned recess is connected with the nozzle outlet at the forward displacement of the valve body against the action of the spring.
