4. Delivery valve according to claim 1 , characterized in that the first settable maximum volume flow is set as standard, and the second settable maximum volume flow is set only when the sensor device ( 20 , 21 ) detects a corresponding signal emitter ( 29 ) assigned to the tank of the motor vehicle.
5. Delivery valve according to claim 1 , characterized in that the control device ( 24 , 25 ) and/or the sensor device ( 20 , 21 ) require no external energy.
6. Delivery valve according to claim 1 , characterized in that the sensor device ( 20 , 21 ) is configured for detecting a magnetic emitter ( 29 ) assigned to the tank of the motor vehicle.

8. Delivery valve according to claim 6 , characterized in that the sensor device ( 20 , 21 ) has a magnet ( 20 ) which is arranged displaceably in the region of the outlet pipe of the delivery valve and which is connected to a mechanical signal transmission device ( 21 ) for transmission of a control signal to the control device.
9. Delivery valve according to claim 8 , characterized in that the mechanical signal transmission device has a signal rod ( 21 ) which is kinematically coupled to the displaceably arranged magnet ( 20 ) and which is displaceable in the axial direction of the outlet pipe of the delivery valve.
10. Delivery valve according to claim 9 , characterized in that in the region facing away from the displaceably arranged magnet ( 20 ), the signal rod ( 21 ) is configured for closing or opening a pressure channel ( 23 ).
11. Delivery valve according to claim 9 , characterized in that in the region facing away from the displaceably arranged magnet ( 20 ), the signal rod ( 21 ) has a first control magnet ( 31 ) which is configured for interaction with a second control magnet ( 32 ) of the control device.
12. Delivery valve according to claim 1 , characterized in that the active connection between the sensor device and the control device takes place by pressure, mechanically and/or magnetically.
13. Delivery valve according to claim 1 , characterized in that the control device ( 24 , 25 ) is configured to set a first and a second maximum opening lift of a main valve of the delivery valve.
