Camshaft phaser with target wheel washer

A camshaft phaser, comprising:

• a stator:
• arranged to receive rotational torque;
• including a plurality of radially inwardly extending protrusions;
• and,
• supported for rotation around an axis of rotation;
• a rotor:
• including a plurality of radially outwardly extending protrusions circumferentially interleaved with the plurality of radially inwardly extending protrusions;
• and,
• arranged to non-rotatably connect to a camshaft;
• a plurality of phaser chambers, each phaser chamber circumferentially bounded by:
• a radially inwardly extending protrusion included in the plurality of radially inwardly extending protrusions;
• and,
• a radially outwardly extending protrusion included in the plurality of radially outwardly extending protrusions;
• an annular washer;
• and,
• a target wheel:
• including a first portion axially located between the annular washer and the rotor and in contact with the annular washer;
• including a radially inwardly extending protrusion;
• and,
• arranged to detect a rotational position of the rotor for use in rotating the rotor with respect to the stator, wherein a hypothetical line, parallel to the axis of rotation, passes through, in sequence, the rotor, the first portion of the target wheel, the annular washer, and the radially inwardly extending protrusion.

• including a radially inwardly extending protrusion, separate from the first portion, overlapping the annular washer in an axial direction parallel to the axis of rotation;
• and,
• arranged to detect a rotational position of the rotor for use in rotating the rotor with respect to the stator.
