Abstract (en)
By-pass valve (20) for a fluid-supply group, in particular fuel, wherein the main shutter (21) is equipped with a ledging flange (24) which co-operates with the valve body (25) and a double auxiliary shutter (26) operates between the hydraulic circuit after the centrifugal degasser (6) and the suction pipe (2) of the pump (1), said auxiliary shutter (26) being reactivated by a spring (27) which opens it in correspondence with a certain pressure value of the fuel, which is lower than the operating pressure with the pistol open. <MATH>
