Abstract (en)

[origin: EP3770383A1] A mechanism for adjusting a camshaft of an internal combustion engine comprises a camshaft (1), a cam sleeve (2) and an electromagnetic valve (3). A guide boss portion (7) is provided on the cam sleeve (2). A valve core of the electromagnetic valve (3) is in fit with the guide boss portion (7) to drive the cam sleeve (2) to perform reciprocating movement in an axial direction of the camshaft (1). An automatic return device is provided on the valve core. After the electromagnetic valve (3) is deenergized, the valve core returns to an initial position under the action of an automatic reset device.
