A spark phase change device for endothermic engines, including at least: phase sensor means related to a certain angular position of the engine shaft "PV": an ignition group "CD", timer means "Tz1, Tz2" directly or indirectly operated or controlled by said phase sensor means "PV"; an interruption means of the electric circuit "SW" operated or controlled by said timer means "Tz1" and by said phase sensor means "PV"; shunting means "D1" of said timer means "Tz2"; logic operation means "OR-I1" operated by said electric circuit interruption means "SW" and by said shunting means "D1", characterized in that the change of the phase is carried out by a first gradual changing phase included in the time of the signal of the phase sensor "PV" controlled by said timer means "Tz1" that operate the interruption means of the electric circuit "SW". |
