DEFORMATION OF A VALVE SEAT FOR IMPROVING A LUBRICATOR PUMP UNIT AND LUBRICATION SYSTEM OF A LARGE SLOW-RUNNING TWO-STROKE ENGINE, AND AN IMPROVED LUBRICATOR PUMP UNIT

摘要

Deformation of a valve seat for improving a lubricator pump unit and lubrication system of a large slow-running twostroke engine, and an improved lubricator pump unit By deforming the valve-seat (23) of a non-return valve system (102) in a lubricator pump unit (11), especially of the Alpha-type, a lubrication system in a large slowrunning two-stroke engine is improved.
