    Abstract: A camshaft arrangement comprising a camshaft, a vane-type camshaft phaser attached to a first end of the camshaft, a valve actuating arrangement and an oil control valve. The oil control valve comprises an elongated valve member arranged centrally inside the camshaft. The elongated valve member can be adjusted in a longitudinal direction of the camshaft to control the oil flow to the vane-type camshaft phaser by actuation of an actuator. The valve actuating arrangement comprises a first valve actuating configuration attached to the camshaft and a second valve actuating configuration comprising an actuation arm connected to the actuator. The first valve actuating configuration is arranged to be actuated by the actuation arm of the second valve actuating configuration.

    Abstract: An assembly for use with an electric motor, including a shaft with on a first end and on a second end a rotatable gear. Each gear is fixedly connected to a first clutch member that can slipping engage a second clutch member extending around the shaft and connected to the shaft in a fixed angular position. A force member is axially situated between the clutch members for moving second clutch members relative to the first clutch members in an axial direction such that the first clutch members and the second clutch members can engage and disengage in a slipping manner at relative circumferential speeds.
