FIG. 14 shows, schematically, communication betweenprogram cards 39 of a vehicle-based VCM andprogram cards 40 of pump-based PCM:s, each VCM card comprising fourchannels 41 corresponding to four tanks of the vehicle and each PCM comprising twochannels 42 corresponding to two pumps by means ofpump 23′ ID transferred via the gun/tank inlet connection to the VCM, a check being intended to be performed between the VCM card channel and the PCM card channel in order to check that a correct liquid is refilled to the tank of this channel. Of course, the card may be designed to comprise only one channel or more channels, e.g. two or four as inFIG. 14 . - The different storing arrangements shown in
FIG. 15 are specifically arranged for handling liquid solutions for selective catalytic reduction, especially AdBlue®. For this, therespective containers 43, tanks, are provided by a temperature sensor for supervision of the solution temperature, AdBlue® specifically freezing at about −11° C. Further, each container is provided with means (not shown) for measuring the container content in order to keep a strict record of the consumption, incoming amount and outgoing amount. This shall be the case irrespective of if the container is part of a comparatively small stand-alone unit 44,FIG. 15 a, amobile unit 45 with pump arrangement etc.,FIG. 15 b, or integrated in a service and refillingdepot 46,FIG. 15 c. - The methods as well as the function of the systems and other arrangements according to the invention should to a substantial part have been made clear from the description given above.
- Thus, the basic method and system function is the ones described in association with
FIG. 13 , the main idea being to fully control and supervise the spill-free refilling process, keeping record of the liquid consumption as well as liquid input and output of the system together with additional information for statistics etc. This goes especially for AdBlue® or the corresponding liquid solutions for SCR since it is very important that the correct product, e.g. AdBlue®, is used and that it is used in amounts specified for a certain diesel engine. - Furthermore, also the components of the described systems are adapted for liquids like AdBlue® or other corresponding SCR liquids, spill-free and liquid-tight performance being an important feature.
- Crystal formation at air exposure has been considered for certain components of the systems and arrangements, especially for the spill-free coupling parts. Thus, in the first coupling part, e.g.
FIG. 3 a, aninternal space 42 available for axial movement of an internal ring-shapedelement 43 against a spring force for opening the coupling part is arranged so that it is always exposed to the liquid, a sealing 44 between the outerperipheral surface 45 of said element and theinner surface 46 of an element-guidingsleeve part 47 of the coupling preventing air from entering into said space, whereby crystal formation is prevented. - Part of the present invention are also computer programme product comprising a programme code for performing method steps of, primarily, anyone of the attached claims 21-34, 48 and 49. The programme code may e.g. be stored on a computer readable media or directly stored in an internal memory of a computer. According to preferred embodiments the necessary computer capacity and the corresponding memory capacity are part of both the VCM and the PCM further computer program products are specified in claims 53-59 as part of the present invention.
- Above, the invention has been described in association with preferred embodiments.
- Of course, further embodiments and minor changes and additions may be imagined without leaving the basic inventive idea.
- Thus, according to preferred embodiments the
other housing 33,FIGS. 10 and 11 , is made up of twohalves 33′, 33″ corresponding to each other and being arranged to be put and held together as a cover for theinner housing 32 comprising the valve arrangement. The outer housing provides anopening 15″ for thelink element 15, a part of said element being arranged to protrude out of the opening in the revised connection position described above. - The outer
housing end part 33 a being intended to be turned to a pipe, not shown, for liquid provision to the gun, also provides a seat 33 b for holding the inner housing end part and valve connection 32 a, and aseat 32 b for theliquid input connection 22, theconnection 22 comprising flange means 22′ being rotatably clamped in said seat offering a swivel configuration for theconnection 22 in the outer housing end part 33 b, the connection being intended to be e.g. by means of O-rings 22″, sealingly introduced into the inner housing end part 32 a. - Further, according to a preferred embodiment a locking
arm 20 a,FIGS. 7 and 10 e.g., is provided for releasably holding the trigger handle 20′, in a refilling position, i.e. upwards from the non-refilling position shown in e.g.FIG. 10 , the locking arm being arranged in the rear end of the outer cover and having afastening piece 20 a′ in its end turned from the trigger handle, a preferablyplatelike push piece 20 a″ in its other end, this end being free, and asupport piece 20 a′″ turned to the trigger handle between said ends, the looking arm being resilient and intended to be pushed against a spring force from a non-locking position shown in e.g.FIG. 11 to a locking position in which thefree end 20′″ of the trigger handle in a refilling position rests upon the support piece preferably by means of a groove, not shown, in the trigger handle free end, the locking arm by its resilience being intended to return to the non-locking position when the trigger handle is lifted and thus releases thesupport piece 20 a′″ and thus permitting the trigger handle to return to the non-refilling position. The locking arm is preferably made of a polymeric material in one piece. - Also it should have been made clear that the invention, although especially designed for a solution for SCR, such as AdBlue®, to a considerable extent is applicable for other liquids, such as diesel fuel, other vehicle fuels etc., and for other applications than vehicles. Also issued have been made clear that, although the invention is especially designed for vehicles and refilling related to vehicles, the application of the invention for vehicles should be considered as an example, the invention being applicable for other objects than vehicles, e.g. stationary objects of various kinds. Thus, the tank subject to refilling does not have to be a vehicle tank but e.g. a stationary or mobile storage tank. Furthermore, the pump does not have to be stationary but may e.g. be carried by a vehicle. Further, a
locking arm 20a are described above may be applied in other guns for refilling and not only in the ones described here. - Thus, the invention shall not be considered limited to the embodiments shown but may be varied within the scope of the attached claims.
