FUEL SAVER WITH A BACKFLOW PREVENTION DEVICE OF HIGH EFFICIENCY

摘要

PURPOSE: A fuel saving device for a vehicle with an anti-backflow unit with an efficiency-enhanced structure is provided to improve operation reliability as the valve assembly is embedded in a housing with a simplified structure. CONSTITUTION: A fuel saving device(10) for a vehicle comprises an anti-backflow unit(20). Main pipelines are respectively connected to inlet and outlet ports. The anti-backflow unit is installed in bypass pipelines branched from the main pipeline, and bypasses the backflow of fuel. The anti-backflow unit comprises a housing(21) and a valve body(30). The inlet and outlet ports(22,23) are formed on both ends of the housing so that the housing is linked to the bypass pipeline. A cylindrical chamber(24) is formed inside the housing. The valve body is embedded in the chamber and opens and closes the inlet and outlet ports.
