Abstract:
A phaser including a housing and a rotor disposed to rotate relative to each other, the housing having at least one cavity disposed to be divided by a vane rigidly attached to the rotor, the vane dividing the cavity into a first chamber and a second chamber, the phaser further including passages connecting the first and the second chamber facilitating the oscillation of the vane within the cavity, the phaser comprising:a) a valve disposed to form at least two openings for fluid flowing between the first chamber and the second chamber and being disposed to keep at least one opening closed; and b) at least one by-pass disposed to stop or slow down the rotation between the housing and the rotor, thereby allowing a locking mechanism to lock the housing and the rotor together independent of fluid flow.
