  • Rotary positive displacement mechanism
    Patent number: 4391574
    Abstract: A device having a power rotor and a seal rotor which have coincident center points. The power rotor rotates in a plane which is perpendicular to that within which the seal rotor rotates. The power rotor has a rotor body to which are attached a plurality of outwardly extending vanes. The seal rotor has a rim gear to which are attached a plurality of inwardly extending vanes. The power rotor vanes and the seal rotor vanes interdigitate upon rotation of the rotors to define two variable volume chambers. The power rotor vanes and the seal rotor vanes are designed and constructed to insure a close mesh during such interdigitation and means are provided for adjusting the position of the power rotor vanes relative to the seal rotor vanes to insure proper interdigitation.
