Abstract:
An improved double action planetary motion machine having a rotor rotating in a planetary motion cycle having a number n of apices, n being equal to at least three, and having a central rotor axis, said n apices being arrayed symmetrically around said central rotor axis;said rotating rotor having at least n rotor faces, said rotor faces being curved surfaces disposed to connect each said one apex of said n apices to an adjacent apex of each said one of said n apices, said n rotor faces being disposed generally parallel to said central rotor axis; said rotating rotor having two parallel rotor sides similar in shape and disposed perpendicularly to said central rotor axis; said planetary motion machine having a mechanical rotational linkage from axial rotation to planetary rotation between an axially rotating driving means and said rotor rotating in a planetary motion cycle; said planetary motion machine having a machine housing; said machine housing having a side housing; said side housing having a peritrochoid cavity interior to said side housing; said machine housing having two parallel sides disposed perpendicularly to said central rotor axis, said sides being two parallel side plates; said peritrochoid cavity having cavity sides interior to said machine housing generally parallel to said central rotor axis and said peritrochoid cavity further having at least nâˆ’1 lobes and being symmetrically shaped to accommodate said planetary rotation cycle of said rotating rotor; said side housing having a central cavity axis parallel to said central rotor axis; said machine housing and said rotating rotor defining an interior space of p working chambers, p being a number equal to n, each said working chamber being inside said peritrochoid cavity and each said working chamber being formed of the volume enclosed by said peritrochoid side housing, said side plates, and one of said rotor faces; said p working chambers alternately expanding and contracting in size during said planetary rotation cycle as said rotor rotates in planetary motion; said rotor being disposed inside said housing so that said side plates are juxtaposed sealingly with said rotor faces, the improvement comprising:said planetary rotation cycle having consecutive fluid action phases for each said working chamber, said consecutive fluid action phases being at least three, said fluid action phases including an expansion phase, an interphase, and a compression phase, said expansion phase including an intake phase, and said compression phase including an exhaust phase; at least one exhaust duct penetrating each one of said n rotor faces of said rotating rotor, said exhaust duct being formed by an exhaust duct aperture in said rotor in order to allow fluid to pass through said rotor; each said at least one exhaust duct penetrating through each one of said n rotor faces, through said rotor and through one of said rotor sides; rotor exhaust ports defined by each said exhaust duct aperture in each said rotor side; at least one of said side plates having at least m housing exhaust ports, m being equal to at least two, each said m housing exhaust port being an aperture in at least one of said side plates adjacent to each said at least one rotor side having rotor exhaust ports and being disposed around said central cavity axis to allow passage of fluid out of said working chambers from said exhaust duct apertures during portions of said planetary rotation cycle; said m housing exhaust ports being disposed peritrochoidally around said central cavity axis and being disposed to cooperate intermittently with each said rotor exhaust port to allow the passage of fluid from each said one of said p working chambers to at least one of said m housing exhaust ports through said at least one exhaust duct and through said rotor exhaust port during an exhaust phase of said each one working chamber; each said housing exhaust port disposed peritrochoidally being truncated to permit said side plate to intermittently obstruct fluid from flowing out of said rotor exhaust ports during said planetary rotation cycle and to permit said rotor to intermittently obstruct fluid from flowing out of said p working chambers, and further being truncated and disposed to permit said rotor side to intermittently obstruct fluid from flowing out of said p working chambers during said compression phase of at least one of said p working chambers; at least one of said side plates having at least q housing intake ports, q being equal to at least two, each said q housing intake port being an aperture in at least one of said side plates adjacent to each said at least one rotor side and being disposed peritrochoidally around said central cavity axis to allow passage of fluid into said working chambers during said intake phase of each of at least one of said p working chambers during said planetary rotation cycle; each said housing intake port disposed peritrochoidally being truncated and disposed to permit said rotor side to intermittently obstruct fluid from flowing into said p working chambers during a compression phase and exhaust phase of at least one of said p working chambers; each said rotor exhaust port, each said housing exhaust port, and each said housing intake port being further disposed to cooperate intermittently with said rotating rotor to intake fluid during part of said planetary rotation cycle into at least one of said at least p working chambers if said exhaust duct into said at least one working chamber is not juxtaposed to a housing exhaust port, if said exhaust port for said working chamber is occluded by said rotor side, and if said working chamber is juxtaposed to an intake port; said housing intake ports, said rotor exhaust ports, and said housing exhaust ports being disposed to cooperate with said rotor side so that during said intake phase for each of said p working chambers, said rotor side does not block said housing intake port for said each working chamber, and said rotor exhaust port is not juxtaposed to said housing exhaust port for said each working chamber; said housing intake ports, said rotor exhaust ports and said housing exhaust ports being disposed to cooperate with said rotor so that during said interphase for each of said p working chambers, said rotor side occludes said housing intake port and said exhaust port for said each working chamber, and said rotor exhaust port for each said one of said p working chambers continues to not be juxtaposed to a housing port; said housing intake ports, said rotor exhaust ports, and said housing exhaust ports being disposed to cooperate with said rotor said so that during said exhaust phase for each of said p working chambers, said rotor side continues to occlude said housing intake port, and said rotor exhaust port for each said one of said p working chambers is juxtaposed to a housing exhaust port; said housing intake ports, said rotor exhaust ports, and said housing exhaust ports being disposed to cooperate with said rotor said so that during said exhaust phase for each of said p working chambers, said rotor side occludes said housing intake port, said rotor exhaust port is juxtaposed to said housing exhaust port and fluid in said one of said p working chambers is exhausted through said exhaust duct aperture, said rotor exhaust port, and said housing exhaust port; said housing intake ports, said rotor exhaust ports, and said housing exhaust ports being disposed to cooperate with said rotor so that for one planetary cycle of said rotor, a double action planetary machine results for each said lobe.
