Abstract
Oppfinnelsen gjelder et apparat for fluidtildeling og som omfatter: et fluidreservoar med variabelt volum og en fluidkanal som fører fra dette til et fluidutløp, et første fluidinnløp og et andre fluidinnløp, en første detektor anordnet for å detektere fluidstrømning mellom nevnte kanal og nevnte reservoar, en første ventil anordnet for å tillate eller hindre fluidstrømning fra nevnte første innløp gjennom nevnte kanal og inn i nevnte reservoar, en andre ventil som i en første ventilstilling tillater fluidstrømning fra nevnte andre innløp gjennom nevnte kanal til nevnte utløp og forhindrer fluidstrømning fra nevnte reservoar gjennom nevnte kanal til nevnte utløp, samt i en andre ventilstilling tillater fluidstrømning fra nevnte reservoar gjennom nevnte kanal til nevnte utløp og forhindrer fluidstrømning fra det andre utløp gjennom nevnte kanal til utløpet, en andre detektor anordnet for å detektere fluidstrømning inn i nevnte kanal fra det andre innløp, og en aktivator anordnet for å styre arbeidsoperasjonen for nevnte første og andre ventil.The invention relates to a fluid delivery apparatus comprising: a variable volume fluid reservoir and a fluid channel leading thereto to a fluid outlet, a first fluid inlet and a second fluid inlet, a first detector arranged to detect fluid flow between said channel and said reservoir, a first valve arranged to allow or prevent fluid flow from said first inlet through said channel and into said reservoir, a second valve which in a first valve position permits fluid flow from said second inlet through said channel to said outlet and prevents fluid flow from said reservoir channel to said outlet, and in a second valve position permits fluid flow from said reservoir through said channel to said outlet and prevents fluid flow from the second outlet through said channel to the outlet, a second detector arranged to detect fluid flow into said second channel , and a activator arranged to control the operation of said first and second valves.
