Abstract: The present disclosure relates to a dispensing gun with increased safety. The dispensing gun comprises an expansion chamber into which liquid trapped inside the dispensing gun can escape in case of expansion of said liquid, thereby avoiding an increase of pressure inside the dispensing gun resulting from such an expansion which could damage internal components, such as the outlet valve arrangement.

Abstract: A dispensing device which ensures that a dispensing procedure cannot be initiated unless a firm coupling to a male coupling of a recipient is achieved is disclosed. The dispensing device comprises a coupling body, an inner flow sleeve, a release sleeve, at least one locking element arranged in a radial opening of the coupling body and a retaining collar axially movable between a first and second position. The dispensing device further comprises means for allowing axial movement of the release sleeve towards the dispensing end of the gun, and may comprise means for allowing axial movement of the inner flow sleeve away from the dispensing end of the device, when the retaining collar is in the second position.

Abstract: Method for spill free refuelling includes establishing a liquid tight connection between a refuelling gun nozzle for fuel dispensing and a coupling piece of the fuel receiving object (6), through which fuel is provided to a fuel container (7), detecting a predetermined fuel level (8?) and automatically interrupting the fuel flow when said level is detected. A level detection signalling configuration is established by moving the gun into position for establishment of the liquid-tight connection. The invention further relates to a system for spill free refuelling, a method and a device for detecting a predetermined liquid fuel level and a fuel pipe arrangement.

Abstract: Method for spill-free refilling for a liquid solution selective catalytic reduction, SCR, an exhaust after-treatment technology for diesel engines. The method includes the steps of establishing a liquid-tight connection between a coupling part of a tank (37), and a coupling part of a dispensing nozzle of a gun (9) for spill-free refilling. A system for spill-free refilling of liquids and a gun for spill-free refilling of liquids, a connection for a vehicle tank, a method and a system for control and communication in a spill-free liquid re-filling system, a method and a system for media provision in a spill-free refilling system, a spill-free and liquid-tight refilling connection and computer programme products are disclosed.
