Abstract:
In an assembly including a housing drivingly connected to a drive unit for rotation about a first axis and an actuator member mounted within the housing for concurrent rotation with the housing about the first axis and axial movement relative to the housing along the first axis through indefinitely variable positions in order to selectively control an operating parameter of the assembly, a sensing system comprising, in combination: a first sensor element attached to the actuator member so as to both rotate in unison with the actuator member about the first axis and to shift in unison with the actuator member along the first axis; and a second sensor element fixed to the drive unit, with the second sensor element being adapted to sense both a rotational condition of the first sensor element about the first axis and a degree of shifting of the first sensor element in order to develop signals indicative of a rotating speed and axial position of the actuator member.
