Patent ID: 8356585

Claim:
A planetary rotary apparatus comprising: a pair of end walls and a housing having an interior sidewall, said end walls and said interior sidewall defining a housing chamber, one of said end walls including an intake port and a rotary intake valve operatively mounted to said end wall outside of said housing chamber, said rotary intake valve having a valve opening with said valve opening being selectively rotated into alignment with said intake port; a plurality of rotors, said rotors being rotatable in concert within said housing chamber with the axes of rotation of said rotors extending between said end walls; an inner chamber defined between at least a portion of said rotors; adjacent and overlapping first and second rotor chambers, said interior wall including a first chamber wall portion and an adjacent second chamber wall portion, said first and second chamber wall portions being approximately semicircular with said first rotor chamber being partially defined by said first chamber wall portion and said second rotor chamber being partially defined by said second chamber wall portion, one of said rotors comprising a first rotor rotating within said first rotor chamber and another of said rotors comprising a second rotor rotating within said second rotor chamber; said first rotor chamber including a compression intake port, said compression intake port selectively enabling a charge to be provided into an outer volume of said housing chamber where said outer volume expands between said first and second rotor chambers during rotation of said first and second rotors with said charge being drawn through said compression intake port during expansion of said outer volume, said charge comprising air or a mixture of air and atomized fuel; said second rotor chamber including a transfer port, said charge becoming a compressed charge when said outer volume is decreased by continued rotation of said first and second rotors with said compressed charge being discharged through said transfer port out of said housing chamber; and a charge manifold, said charge manifold extending between said transfer port and said rotary valve with said compressed charge being delivered through said charge manifold and said rotary valve into said inner chamber when said valve opening aligns with said intake port.
