Abstract (en)

There is provided a mechanical locking pin assembly comprising a hollow cylindrical locking pin retractable into the through bore and having an extended position protruding from the member, a spring seat for mounting within the through bore to grip the inner wall of the through bore, and a spring disposed within the locking pin and acting on the spring seat to urge the locking pin away from the spring seat toward the extended position. The spring seat comprises an end plate and plurality of protrusions extending axially from the perimeter of the end plate toward the locking pin. Complimentary axially extending slots are formed in the cylindrical side wall of the locking pin for receiving the protrusions of the spring seat in both the extended and retracted positions of the locking pin. When used in a cam phaser, this proposal enables a phaser of a shorter overall length.
