Abstract (en)
[origin: EP1589196A2] A hydraulic timing adjustment for a camshaft of an IC engine has an outer rotor (202) driven from the crankshaft and an inner shaft (204) connected to the camshaft. Tilt mounted flap levers (234) link the inner shaft and the outer rotor and move in hydraulic spaces formed between the flap levers and radial spacers (212). The tilt levers are pivot mounted at one end via ball and socket mountings with the free ends locating in closed bores in the outer ring. The sides of the tilt levers are profiled with a cylindrical drop profile in the centre to interact with profiled surfaces of the radial spacers to form trapped volumes which effectively dampen the end settings of the tilt levers.
