Valve actuator for IC engine - has tube with transverse bore, fitted with radial play through insert

摘要

The actuator incorporates a tube (20) with a cross bore (28). The bore extends from the interior (29) of the tube, and opens in the tube jacket near the rear face (30) of the coupling pin (12). The tube passes with radial play (31) through the insert (18), which sits in the bore (10) of a lever (5). USE/ADVANTAGE - Single/multi-valve engines. Shortened response time. Rear of coupling pin is fully charged by pressure medium without delay, so that pin moves quickly and completely into bore in other lever.
