F01L2001/34476 - CPC Classification

Classification description:

Valve-gear or valve arrangements, e.g. lift-valve gear characterised by the provision of means for changing the timing of the valves without changing the duration of opening and without affecting the magnitude of the valve lift changing the angular relationship between crankshaft and camshaft, e.g. using helicoidal gear using hydraulic chambers with variable volume to transmit the rotating force; Details relating to the hydraulic means for changing the angular relationship; Locking means between driving and driven members Restrict range locking means
