Abstract

The invention relates to a thermostatic valve for fuel circuits, which is intended to establish a distribution of the circulation of hot fuel of the injection pump return of an engine, comprising an outer casing (1), inside which there is housed a functional assembly determining a central chamber (5) which communicates with a tube (3) for connection with the injection pump return and which is provided at the ends with respective check valves (8 and 9) closing said central chamber (5) with respect to a tube (2) for the connection towards the fuel tank and with respect to an outlet (4) for communication with the filter of the fuel circuit, facing which a closing and opening bimetal (13) is arranged.
