Abstract:
A fuel supply system for a motor vehicle has a sucking jet pump (6, 7) which is connected to a flow line (5). The valve (16, 17) reduces the cross-section of an opening (20) in a nozzle (14, 15) of the sucking jet pump (6, 7) with increasing pressure in the flow line (5). Hydraulic losses in supplying the sucking jet pump (6, 7) with fuel as a pump fluid are prevented and the conveying performance of the sucking jet pump (6, 7) is maintained, preferably, at a constant level.
