FUEL TANK SHUTOFF VALVE, MEASUREMENT SYSTEM FOR USE WITH FUEL SYSTEM, FUEL SYSTEM AND VEHICLE Russian patent published in 2020 - IPC B60K15/35 F02M25/08 

FIELD: transport machine building.

SUBSTANCE: invention relates to fuel tank shutoff valves, particularly, for use with hybrid vehicle systems. Shutoff valve of fuel tank is made with possibility of fluid communication with fuel tank and coal filter of fuel system, at that, FTSV comprises integrated controller and solenoid, connected to valve, wherein solenoid is configured to move between normally closed position, in which the valve is closed and prevents communication via fluid through the first path of the FTSV flow, and an open position, in which valve is open and communicates via said first flow path, wherein said integrated controller is configured to output actuation signals to solenoid in response to signals containing information on parameters, obtained from one or more sensors associated with fuel tank, wherein the fuel tank shutoff valve is configured to provide said open position at least in response to receiving an opening signal from the central fuel system controller. Besides, the invention proposes a measurement system for use with a fuel system, comprising a FTSV and at least one such sensor. In addition, proposed is fuel system containing fuel tank and carbon filter, and also containing measurement system for use with it.

EFFECT: reduced total power consumption of fuel system; reduced heat released by components of fuel system; improved control over opening/closing of fluid passage channel from fuel tank to coal filter.
