Variable control for IC engine valves - has axially slidable camshaft with conical cams and includes tilting lever with rotary parts.

摘要

The control has a driven part (5), transmitting the drive by pins (4) to the camshaft (11). At increased speed, the centrifugal force overcomes the weights (6), held by springs (7), for sliding the camshaft in plain bearings (1), using sliders (2), in the dissection of the control part (3). The camshaft connected pins penetrate into the control part for bringing the camshaft into contact with the central part. On reduced speed, the weights are compressed by the springs until the sliders abut the control part. The conical cams (9) slide w.r.t. the tilting levers (8) for the change of the valve opening. USE/ADVANTAGE - Variable control for IC engine valves operates without need for a hydraulic system.
