Abstract

A phaser for an engine having at least one camshaft comprising a housing, a rotor, a control valve, an actuator, and a pulse wheel. The rotor connects to a camshaft coaxially located within the housing. The housing and the rotor define at least one vane separating a chamber in the housing. The vane is capable of rotation to shift the relative angular position of the housing and the rotor. The control valve is received by the rotor and directs fluid to the chambers of the phaser. The actuator positions the control valve and has at least one integrated position sensor, such that electrical connections for the actuator and the integrated position sensor are made through one connection, decreasing leakage of fluid from the phaser. A pulse wheel is mounted on the phaser for rotation therewith and in alignment with the integrated position sensor of the actuator.
