Abstract

L'invention propose un moteur thermique deux temps comportant au moins un cylindre axial (12) comportant un alésage (14) qui reçoit en coulissement au moins un piston (16) et qui comporte une pluralité de lumières périphériques (34) inférieures aptes à être ouvertes ou fermées par le piston (16) en mouvement, de formes sensiblement hexaédrique, qui sont chacune délimitée dans la paroi périphérique (30) par des faces (36, 38, 58, 60) conformées en quadrilatères, comprenant des faces supérieures (36, 38) délimitées par des arêtes (40, 42, 46, 48) dites d'orientation de gaz, caractérisé en ce que les arêtes (40, 42) d'orientation de gaz de la face supérieure (36) forment avec une direction radiale (R) des angles (α40,α42) qui sont orientés selon un premier sens et compris dans une première plage angulaire, et en ce que les arêtes (46, 48) d'orientation de gaz de la face inférieure forment avec la direction radiale (R) des angles (α46, α40) orientés selon un second sens déterminé opposé au premier, et compris dans une seconde plage angulaire.The invention provides a two-stroke heat engine comprising at least one axial cylinder (12) comprising a bore (14) which slidably receives at least one piston (16) and which comprises a plurality of lower peripheral openings (34) capable of being open or closed by the moving piston (16), of substantially hexahedral shapes, which are each delimited in the peripheral wall (30) by faces (36, 38, 58, 60) shaped as quadrilaterals, comprising upper faces (36 , 38) delimited by ridges (40, 42, 46, 48) called gas orientation, characterized in that the gas orientation ridges (40, 42) of the upper face (36) form with a direction radial (R) angles (α40, α42) which are oriented in a first direction and included in a first angular range, and in that the gas orientation ridges (46, 48) of the lower face form with the direction radial (R) angles (α46, α40) oriented in a second determined direction opposite to first, and included in a second angular range.
