UN APARATO DE BOMBEO DE COMBUSTIBLE LIQUIDOS PARA SUMINISTRAR COMBUSTIBLE A UN MOTOR DE COMBUSTION INTERNA

摘要

A liquid fuel pumping apparatus of the rotary distributor type has an electromagnetically operable spill control valve including a valve member which is closed to prevent spillage of fuel from the high pressure pump of the apparatus. A transducer including a core member and a winding is provided to provide signals from which it is possible to determine the instants of spill valve closure and opening. The signals are used in a control system to control the operation of the apparatus.
