Abstract:
1. A fluidic machine comprising: a fixed body ( 1 , 2 ; 101 , 102 ); an external orbital member ( 7 ; 107 ) installed in said fixed body ( 1 ; 101 ), supported and guided by said fixed body for rotation around a first rotational axis, said external orbital member ( 7 ; 107 ) having internal gear teeth comprising a first teeth number; a transmission member ( 3 ; 103 ) installed in said fixed body ( 2 ; 102 ), supported and guided by said fixed body for rotation around a second rotational axis not coincident with said first rotational axis; an internal orbital member ( 5 ; 105 ) supported by said transmission member ( 3 ; 103 ) and solid in rotation therewith, said internal orbital member ( 5 ; 105 ) having external gear teeth comprising a second teeth number different from said first teeth number, and said internal orbital member ( 5 ; 105 ) extending within said external orbital member ( 7 ; 107 ) and having its own external gear teeth meshing, with relative (namely, only partial) fluid seal, with the internal gear teeth of the external orbital member ( 7 ; 107 ), thus determining among the gear teeth of the two orbital members spaces whose volume is variable during the rotation; said fixed body ( 1 ; 102 ) having two chambers ( 22 , 23 ; 122 , 123 ), connected with a low pressure connection ( 20 ; 120 ) and to a high pressure connection ( 21 ; 121 ), respectively; and one of said internal and external orbital members being so shaped as to act as a distributor among said variable volume spaces and said chambers of the fixed body; characterized in that one of said internal and external orbital members ( characterized in that said orbital member intended to act as a distributor is said transmission member (
