Fuel pumping installation supplying engine of motor vehicle from tank

摘要

The turbine pump (34) has a fuel inlet supplied from the storage unit (23) and an outlet to supply the engine. A combination consisting of a fuel injector and a Venturi channel (134) has a fuel inlet coupled to the main fuel tank (18) and a Venturi outlet directed inside the storage unit. A line couples the turbine pump fuel outlet to the injector. A valve between the turbine pump outlet and the injector is biassed to open such that fuel can be supplied to the injector when the turbine pump outlet pressure reaches a predetermined level.
