The invention relates to a filling valve for dispensing a fluid, comprising an inlet opening for connecting to a fluid supply line, an outlet end () which lies opposite the inlet opening, a main valve for controlling the flow of the fluid through the filling valve, and a leakage protection valve () which is arranged downstream of the main valve, comprising a valve seat () and a valve body () which can be moved into a closed position in an upstream direction. According to the invention, the valve body () has a first sub-body () and a second sub-body () which is designed to be movable relative to the first sub-body, wherein a first fluid path () can be released by a movement of the first sub-body () in a downstream direction relative to the valve seat (), and a second fluid path () can be released by a movement of the second sub-body () in a downstream direction relative to the first sub-body (). By virtue of the two-part valve body according to the invention, the flow of fluid through the filling valve can be optimized and the back pressure accumulating in front of the leakage protection valve can be reduced.

Filling valve with leakage protection device

The invention relates to a device for discharging a first fluid and for returning a second fluid, comprising a main channel () for discharging the first fluid and a return channel () for returning the second fluid. According to the invention, a test channel () is provided which connects the main channel () to the return channel (), the main channel () having a narrowing () and the test channel () issuing into the main channel () in the region of the narrowing (). The device further has a sensor () which is designed to determine a pressure in the test channel (). 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.
