Title:
CYLINDER-PISTON ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/1997/047870
Kind Code:
A1
Abstract:
The present invention pertains to mechanical engineering and relates to cylinder-piston assemblies mainly intended for use in two-stroke internal combustion engines. The cylindrical surface of the piston (5) is provided with recesses (9) located between seal rings (6) and containing spring-biased elongate elements (8). These elements provide longitudinal sealing and define together with seal rings (6) an enclosed sealed area on the surface of the cylinder (1) in the region of the gas distributor windows (2, 3). The system described in the present invention may be used to prevent leakage of the last charge and the combustion products from a first window of the gas distributor to the second window through the gap around the piston (5).
