Abstract: 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 (12) 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 (13) which is arranged downstream of the main valve, comprising a valve seat (14) and a valve body (15, 16) which can be moved into a closed position in an upstream direction. According to the invention, the valve body (15, 16) has a first sub-body (15) and a second sub-body (16) which is designed to be movable relative to the first sub-body, wherein a first fluid path (17) can be released by a movement of the first sub-body (15) in a downstream direction relative to the valve seat (14), and a second fluid path (18) can be released by a movement of the second sub-body (16) in a downstream direction relative to the first sub-body (15).

Abstract: A breakaway coupling for connecting two fluid lines, comprising a first coupling part (3) which can be connected to the first fluid line and a second coupling part (4) which can be connected to the second fluid line. The coupling parts (3, 4) can be disconnected from one another by way of a defined disconnecting force, wherein at least one of the coupling parts (3, 4) has an outflow prevention valve (20) with a valve seat (21) and with a sealing body (14) which is configured for interaction with the valve seat (21). The outflow prevention valve (20) has a hold-open element (16) which is configured to enable a passage of the fluid in the joined-together state of the coupling parts (3, 4). The outflow prevention valve (20) is configured to prevent an outflow of the fluid from at least one of the fluid lines in the disconnected state of the coupling parts (3, 4).

Abstract: The invention relates to a nozzle (13) for dispensing a fluid, comprising a manually operated control lever (15), which can be moved between a closed position and an open position in order to control the dispensing of the fluid. According to the invention, the control lever (15) comprises a latching pawl (23), which is designed to engage in a slotted guide (22) of the nozzle (13), the latching pawl (23) being designed to follow an opening movement of the control lever (15) in an opening direction (18) and a closing movement of the control lever (15) in a closing direction (18), the latching pawl (23) being able to be moved, by cooperation with the slotted guide (22), relative to the control lever (15) in a direction perpendicular to the opening and closing direction (18) into a catch position (25), in which the latching pawl (23) fixes the control lever (15) in the open position.

Abstract: 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.

Abstract: The subject of the invention is a dispensing nozzle for dispensing a fluid into a tank of a motor vehicle. The dispensing nozzle comprises the following features: the dispensing nozzle comprises a channel (30) for passing through the fluid, wherein a main valve (5) is arranged in the channel (30), said main valve being movable between a closed position and an open position for controlling a fluid flow, the dispensing nozzle comprises a first maximum volumetric flow rate and a second maximum volumetric flow rate, wherein the second maximum volumetric flow rate is greater than the first, According to the invention it is provided that the dispensing nozzle comprises an adjustable flow limiter (22) which is arranged downstream of the main valve (5) and which is configured to limit the fluid flow selectively to the first or second maximum volumetric flow rate.

Abstract: The invention concerns a delivery valve for the delivery of a fluid into a tank of a motor vehicle. According to the invention, the following is provided: a) the delivery valve has a first settable maximum volume flow, b) the delivery valve has a second settable maximum volume flow which is higher than the first settable maximum volume flow, c) a control device (24, 25), by means of which optionally the first or the second maximum volume flow can be set, d) a sensor device (20, 21), which is configured for interaction with a signal emitter (29) assigned to the tank of the motor vehicle and which activates the control device.
