Abstract
An injection nozzle for use in injecting lubricating oil into cylinders in large engines is provided. 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.
