Abstract

Sono noti pistoni di motori a combustione interna, in cui per migliorare il raffreddamento interno del pistone si inietta olio contro il cielo del pistone aperto in direzione del basamento oppure in cui, dall'esterno del cilindro in cui si muove il pistone, si conduce, attraverso un'apertura corrispondente nella parete cilindrica, aria nell'interno del pistone aperto in direzione del basamento, e che poi l'aria condotta lungo il cielo del pistone e così riscaldata viene estratta dall'interno del pistone e alimentata, tramite un canale corrispondente, alla camera di combustione del cilindro.Il pistone secondo l'invenzione presenta, accanto ad un'alimentazione di olio di raffreddamento (5, 9) mediante la quale viene alimentato olio di raffreddamento e iniettato contro una superficie interna (6) del cielo (2) del pistone, un polmone per aria (16, 17) una cui superficie di parete è la superficie di raffreddamento (6, 40) del cielo (2) del pistone, con l'alimentazione di aria secondo l'invenzione al polmone (16, 17) per l'aria e con il riflusso nel vano interno (20, 21) del pistone si produce una corrente d'aria.L'invenzione è utilizzabile per tutti i pistoni di motori a combustione interna.
