Abstract
A rotary device (,) has a first rotor (,) rotatable about a first axis and having at its periphery a recess (,). A second rotor (,) is counter-rotatable to said first rotor (,) about a second axis, parallel to said first axis, and has a radial lobe (,). The first and second rotors (,) are coupled for rotation and are intermeshed such that, for a portion of the rotation of the rotors (,), there is defined between the first and second rotors (,) a transient chamber of volume which progressively decreases on rotation of the rotors (,). Means (,) are provided for monitoring the clearance between the rotors (,). Means for adjusting the clearance between the rotors (,) are provided.
