A fuel return valve comprises a housing (1) and a closing unit (2), a first passage (4), which is line-connected to a fuel pump, a second passage (5), which is line-connected to an internal combustion engine, and a third passage (6), which is line-connected to the fuel tank, as well as a pressure chamber (8, 16), being formed in the housing, which pressure chamber is in communication with the first passage (4), and, via the closing unit (2), with the third passage (6). To make a valve of this type maintenance-free and simple and inexpensive to produce, a) the closing unit (2) is a piston (25) which is guided in the housing attachment (20) and is pressed by a spring (19) arranged and supported in the housing attachment (20) onto a sealing surface (18) which is formed on the housing (1, 10) and surrounds the pressure chamber (8, 16), and b) an annular chamber (30) which is in communication with the third passage (6) and with the space (24) containing the spring (19) is formed outside the sealing surface (18).
