Abstract

PISTON A DOUBLE EFFET MULTITEMPERATURE Le piston à double effet multitempérature (201) comprend un anneau périphérique d’étanchéité (220), une calotte chaude inférieure (226) et/ou une calotte chaude supérieure (232), et translate dans un cylindre froid (204) d’un moteur thermique (202) qui comprend une culasse inférieure (213) et une culasse supérieure (214), ledit piston (201) comprenant une broche centrale de piston (210) dont la tige inférieure de piston (211) traverse la culasse inférieure (213) pour être reliée à des moyens de transmission de puissance (205) logés dans un carter de transmission (206), et dont la tige supérieure de piston (212) traverse la culasse supérieure (214) pour déboucher dans une chambre de refroidissement et de lubrification de piston (217), une galerie de lubrification-refroidissement (227) aménagée dans ladite broche (210) mettant en communication ladite chambre (217) avec ledit carter (206) via un volume interne de piston (228). Figure pour l’abrégé : Fig. 3MULTI-TEMPERATURE DOUBLE-ACTING PISTON The multi-temperature double-acting piston (201) comprises a peripheral sealing ring (220), a lower hot cap (226) and/or an upper hot cap (232), and translates into a cold cylinder ( 204) of a heat engine (202) which comprises a lower cylinder head (213) and an upper cylinder head (214), said piston (201) comprising a central piston pin (210) of which the lower piston rod (211) passes through the lower cylinder head (213) to be connected to power transmission means (205) housed in a transmission casing (206), and of which the upper piston rod (212) passes through the upper cylinder head (214) to open into a piston cooling and lubrication chamber (217), a lubrication-cooling gallery (227) arranged in said spindle (210) placing said chamber (217) in communication with said casing (206) via an internal piston volume (228) ).
