ABSTRACT:
A distributor for H.T. electrical voltage in an internal combustion engine has a base (2) supporting a cap (60). A shaft (1) arranged to rotate in synchronism with the engine rotation drives an apertured rotating plate (8) which is positioned between a light transmitter and a light receiver forming a signal detection unit (15). Signals from the signal detection unit (15) are outputted via a connector (51). The distributor has an H.T. voltage distribution portion formed by a rotor (14), contacts (20,22) and rotor contact (21). The H.T. voltage portion of the distributor is separated from the signal detection unit (15) by an inverted cup-shaped insulating cover (17) located substantially inside the cap (60). The cover (17) is sealed to the base by an annular seal (18) and to the cap by an annular seal (19). A further seal (82) which is preferably integral with the seal (18) is located about the connector (51) and seals the cover (17) to the connector (51). A ventilation hole (71) may be provided through the cover to vent the H.T. voltage distribution portion to the exterior of the distributor.
