The invention relates to a device for discharging a first fluid and for returning a second fluid, comprising a main channel (13) for discharging the first fluid and a return channel (14) for returning the second fluid. According to the invention, a test channel (15) is provided which connects the main channel (13) to the return channel (14), the main channel (13) having a narrowing (16) and the test channel (15) issuing into the main channel (13) in the region of the narrowing (16). The device further has a sensor (17) which is designed to determine a pressure in the test channel (15). The invention further relates to an outflow tube, a delivery nozzle and a delivery pump having a device according to the invention. With the aid of the invention, active return of the second fluid can be shut off in a simple and safe manner.
