Title:
【発明の名称】バルブ制御機構
Document Type and Number:
Japanese Patent JP2002529635
Kind Code:
A
Abstract:
A valve control mechanism is disclosed which permits either or both of (a) axial displacement of the camshaft of an internal combustion engine, and (b) phasing of the camshaft (and hence of the valve operation)-i.e. an advance/retard function. The mechanism preferably includes a piston housed within a cylinder, this arrangement itself being mounted within a front end camshaft pulley. The piston is under hydraulic control, preferably governed by a microprocessor. A mechanical coupling between the piston and the camshaft translates the axial movement of the piston into one or both of axial displacement of the camshaft and relative advancement/retardation of its rotation.
