ROTARY POSITIVE DISPLACEMENT MECHANISM

摘要

The motor has a power rotor and a seal rotor which have coincident centre-points. The power rotor rotates in a plane perpendicular to that within which the seal rotor rotates. The power rotor has a rotor body to which are attached outwardly extending vanes. The seal rotor has a rim gear to which are attached 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 insure a close mesh during such interdigitation. Controls are provided for adjusting the position of the power rotor vanes relative to the seal rotor vanes to insure proper interdigitation.
