Piston oscillating movement maintaining system for use in e.g. internal combustion engine, has piston conducting oscillating movement between top dead center and bottom dead center, and piston ring arranged on inner side of cylinder tube

摘要

The system has a cylinder tube (30), whose inner side (31) is positioned against an outer piston shell (9) in which a piston (2) is connected flexibly by a piston-pin (3). The pin with its ends (3a, 3b) is accommodated in the piston. The piston conducts an oscillating movement between a top dead center (OT) and a bottom dead center (UT). A piston ring (15d) is arranged on another inner side of the tube. Independent claims are also included for the following: (A) a use of a system in a piston processing machine (B) a use of a system in an internal combustion engine.
