A filling nozzle, comprising an inlet () for the connection of a fluid supply line, an outlet () for dispensing the fluid, a fluid channel (), a coupling device () for converting a movement of a hand lever () into an actuation of a main valve () and a membrane () which separates a first membrane space () from a second membrane space () and which can be moved to actuate the coupling device () by a pressure difference existing between the first membrane space () and the second membrane space (). A vacuum can be applied to the first membrane space (), wherein a sensor line () opens into the first membrane space (). The second membrane space () is sealed with respect to the fluid channel () and is fluidically connected via a ventilation channel () to the surroundings outside the filling nozzle, wherein the fluid flows around a part of the coupling device () situated outside the second membrane space () when the main valve () is opened.

Filling nozzle

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.

Device for discharging and returning fluids

The invention provides a dispensing valve or fuel nozzle having an earth (ground) cable and/or a safety cap for covering the discharge opening, the safety cap connected by a cord to the dispensing valve, wherein the dispensing valve has an automatic retraction system for the earth cable and/or the cord of said safety cap.

Fuel nozzle

The invention relates to a dispensing valve for dispensing liquids into a reservoir container, with a main valve and with an operating lever designed for opening the main valve against a force biasing the main valve into the closed position, wherein the valve actuation mechanism has a continuous characteristic with a smooth profile, with which, when subjecting the operating lever to an actuation force at the start of a valve opening stroke, a different opening force is exerted on the main valve than when subjecting the operating lever to the same actuation force during the later course of the valve opening stroke.
