This type of piston ring is also referred to as nose ring. In combustion engines, the oil is scraped from the sharp running side of the cylinder wall and, if necessary, discharged to the crankcase via the grooves under or in the ring. Slotted oil scraper rings have the same effect. Alternatively, the installation of an expansion ring can provide additional contact pressure on the cylinder wall.
These scraper rings can be used in both external and internal tensioning types in a wide variety of applications. The types shown on this page therefore serve as a starting point to explore all the possibilities.
Indo German Industries focuses on the required functionality and system requirements to subsequently come up with a design that meets these requirements. It may well be that certain properties of other piston ring types can better be used to achieve this result or that completely new elements are used.
The correct geometry is only part of what makes a good piston ring. In addition to the (emergency) running properties on the counter-face material, the composition of the ‘medium’ to be processed is of course also important. In addition to oils, this can be any liquid and/or powder.
