Patent ID: 8689750

Claim:
A camshaft phase adjustment device, comprising: a housing having a first flange having a first opening and a second flange having a second opening, wherein a camshaft is received by the housing and extends through both of the first and second openings, the camshaft including a first end having cams and a second terminal end, the second terminal end received by the second opening; a driving gear member having a first gear disposed between the first and the second flange, a camshaft receiving portion extending from the first gear through the first opening of the first flange and a driveshaft coupling portion positioned on a common side of the housing as the first end of the camshaft, the driveshaft coupling portion configured to transfer rotational motion from the driveshaft to the first gear, and a passage extending through the camshaft receiving portion wherein the camshaft is received through the passage permitting rotation of the camshaft relative to the driving gear member; a second gear and a third gear disposed between the first and the second flange and mounted on an axle secured to the housing and having a longitudinal axis, the longitudinal axis of the axle parallel to a longitudinal axis of the camshaft, the second gear coupled to the third gear such that the third gear rotates with the angular velocity of the second gear, and wherein the teeth of the second gear are meshed with the teeth of the first gear and the teeth of the third gear are meshed with the teeth of a fourth gear; the fourth gear coupled to the camshaft for transferring angular motion of the fourth gear to the camshaft such that the camshaft will rotate with the angular velocity of the fourth gear; and wherein the housing is configured to be coupled to an actuator for rotating the housing about the longitudinal axis of the camshaft.
