Piston 3 slides in said axis C and has front face with central ledge 321. It has also ring 322 arranged around piston head and chamber 323 with rotational axis B extending from central ledge 321 to ring 322 connected therewith nearby ledge 3220 with thickness Ep. Aforesaid chamber 323 comprises torus 3230 arranged, in fact, around ledge 3220 and shaped, preferably, to semidome with maximum radius Rt to direct injected fuel in opposite direction R toward central ledge 321.
