A rotary device is provided. The rotary device includes a housing having a cylindrical inner surface and a rotor assembly mounted for rotation in the housing. The rotor assembly includes a rotor, at least one rocker pivotally coupled to the rotor, and a counterbalanced seal assembly. The rotor includes a central portion and a plurality of arms extending radially outward from the central portion. Each arm has a distal end disposed for sliding engagement with the inner surface. Pivoting of the rocker causes the rotor to rotate. The counterbalanced seal assembly is disposed at the distal end of at least of one of the arms, and includes a seal and a counterweight mechanism. The counterweight mechanism is configured to control a contact pressure exerted by the seal on the inner surface resulting from rotation of the rotor. |
