<p>The present subject matter relates to a low-pressure circuit of a fuel delivery device of a fuel injection system of an internal combustion engine. The low-pressure circuit (10) has a low pressure line (11), which forms an inlet of a delivery pump (13) to a high pressure pump (15), wherein a controllable actuating element (16) conveys a pre-selected supply flow to the high pressure pump (15), and the excess fuel supplied by the delivery pump (13) is discharged into a return line (17) by an overflow valve (30). A T-piece (40), in which the overflow valve (30) is accommodated, is disposed in the low pressure line (11).</p> |
