An aggregate for feeding fuel from a fuel supply tank to an internal combustion engine, the aggregate has a housing through which fuel flows, a feeding pump and a motor which drives the pump, the feeding pump and the motor being arranged in the housing so that behind the feeding pump as considered in a flow direction a pressure chamber limited by the feeding pump is provided, a valve communicating the pressure chamber with an outer chamber, the valve having a closing element which during a normal operation of the feeding aggregate is held in a closing position so that the pressure chamber is separated from the outer chamber, the valve having a first passage with a first fluid flow and communicating the pressure chamber with the outer chamber, a second passage with a second fluid flow flowing around the closing element and leading in a joint opening toward the outer chamber, so that with increasing first fluid flow before and after the closing element as considered in the closing direction a pressure difference is formed and the closing element is transferable from an opening position to a closing position.
