Reciprocating piston engine with adjustable stroke - has adjusting spindle in crank shaft, to adjust intermediate bearing shell for connecting rod bearing

摘要

The engine has an adjusting spindle, located centrally in the crank shaft. The spindle adjusts an eccentric intermediate bearing shell for the connecting rod bearing. The eccentricity of the bearing shell raises or reduces that of the crank shaft. The intermediate bearing shell is locked against return forces. A push rod located in the spindle actuates a slide, which locks in the internal toothing of the bearing shell. A pinion turns a toothed driver ring in one direction, which in turn drives the bearing shell. ADVANTAGE - Better performance over speed range of engine.
