  • Patent number: 9726200
    Abstract: A modular ejector pump (1) for a fuel delivery device (39). The ejector pump (1) has a feed line (3) and a first nozzle (7). The feed line (3) is embodied to supply fuel (27) to the first nozzle (7). The ejector pump (1) furthermore has a second nozzle (9), which is arranged parallel to the first nozzle (7). The feed line (3) is embodied to supply fuel (27) to the second nozzle (9).
    Type: Grant

  • Publication number: 20110000468
    Abstract: Devices for feeding fuel are already known which have a storage pot which can be filled by a suction jet pump. The storage pot has a pot base with an intake opening which opens into an intake chamber of the suction jet pump and through which the suction jet pump sucks in fuel. The intake chamber is fluidically connected to the storage pot via a mixer duct. A non-return valve is provided in the intake opening in order to prevent fuel from back-flowing. Considerable flow turbulence occurs within the suction jet pump, which flow turbulence can lead, in particular in the case of heated fuel, referred to as hot petrol, to the formation of gas bubbles. The delivery capacity of the suction jet pump is considerably reduced by the gas bubbles, with the result that under certain operating conditions the storage pot is not sufficiently filled and can run empty. In the device according to the invention, the flow turbulence is reduced.
