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.
Method for spill-free refilling for a liquid solution for selective catalytic reduction, SCR, an exhaust after-treatment technology for diesel engines, said method comprising the steps of establishing a liquid-tight connection between a coupling part (5) of a tank (37), and a coupling part (6) of a dispensing nozzle (9′) of a gun (9) for spill-free refilling.
A system for spill-free refilling for a liquid solution for selective catalytic reduction, SCR, an exhaust after treatment technology for diesel engines, the system comprising means (5,6) for establishing a liquid-tight connection between a coupling part (5) of a tank (37) and a coupling part (6) of a dispensing nozzle (9′) of a gun (9) for spill-free refilling.
Gun for spill-free refilling of liquids comprising a dispensing nozzle, a handle part, a trigger with a trigger handle, a valve arrangement to be activated by the trigger, and a liquid input connection for connecting the gun to a liquid provision pipe, the nozzle comprising a nozzle coupling part arranged to be releasably connected to a tank coupling part to form a liquid-tight connection for spill-free transfer of liquid from the gun to the tank, characterized in a release sleeve (14) arranged substantially outside of the nozzle (9′) coupling part (6), the sleeve being axially movable by means of a link element (15) from a coupling position to a release position and comprising flange means (13) arranged to co-act with flange means (12) of a coupling collar (11) of said nozzle coupling part to move said coupling collar axially into a release position.
Connection for a tank for a liquid, the connection being for spill-free refilling and comprises a tank coupling part arranged to be connected to a refilling gun coupling part for spill-free refilling, characterized by inlet (1,1′) in the form of a preferably cylindrical pipe part (2) protruding from a tank wall piece (3), and an adapter (4,4′) to be fitted axially into the tank inlet and carrying the tank coupling part (5).
Method for control and communication in a spill-free refilling system, characterized in that refilling of at least one tank (37) is controlled by means of wireless two-way communication between a control and communication module (VCM) associated with the tank, and a pump equipment-mounted control and communication module (PCM).
System for control and communication in a spill-free refilling system, characterized by a wireless two-way communication system for communication between a control and communication module (VCM) associated with at least one tank that is to be refilled and a pump equipment-mounted communication module (PCM) for controlling refilling of at least one vehicle-mounted tank (37).
Spill-free and liquid-tight refilling connection comprising a first coupling part carried by a refilling gun for spill-free refilling and a second coupling part carried by a tank inlet, the coupling parts being arranged to co-act in order to open a refilling connection in at least two steps, the first coupling part opening the second coupling part, which thereafter opens the first coupling part, and to close the refilling connection in at least two steps, the first coupling part first being closed and thereafter closes the second coupling part when the connection is released, characterized in that the first coupling part (5) comprises a coupling collar (11) movable between a coupling position and a release position and comprising flange means (12) arranged to co-act with flange means (13) of a release sleeve (14) of the gun arranged to be moved axially from a coupling position to a release position for moving the coupling collar to the release position of the coupling collar.
Method for media provision in a spill-free refilling system comprising a storage tank for a refilling liquid medium, characterized in that said medium is a liquid solution for selective catalytic reduction, SCR, an exhaust after-treatment technology for diesel engines and in that the storage tank (43) content is measured to keep re-cord of input and output of said liquid solution and in that the temperature of the liquid solution preferably is measured.
