Claims (11)

1. En pumpe omfattende et hus (1), huset omfatter en første fluidseksjon (2) og en andre fluidseksjon (3) adskilt ved et resiprokerende pumpeelement (4), hvor - den første fluidseksjonen (2) omfatter et innløp/utløp (5) for et drivfluid; - den andre fluidseksjonen omfatter et innløp (6) og et utløp (7) for en væske, hver av innløpet og utløpet omfatter en enveisventil (8,9), slik at en væske kan gå inn i den andre fluidseksjonen (3) via innløpet (6) og blir tvunget ut av den andre fluidseksjonen (3) via utløpet (7) ved bruk; og - det resiprokerende pumpeelementet (4) er bevegelig mellom en første posisjon, hvor volumet til den første fluidseksjonen (2) er minimalisert og en andre posisjon, hvor volumet til den første fluidseksjonen (2) er maksimalisert; hvor pumpen omfatter dempemidler (4,10,13) anordnet slik at det resiprokerende pumpeelementet møter en økt bevegelsesmotstand når det ved bruk nærmer seg henholdsvis den første og den andre posisjonen, og erkarakterisert vedat dempemidlene omfatter minst ett fluidstrømsbegrensende element (10,4) anordnet for å gradvis minske et tverrsnitt til en fluidstrømspassasje (lla,llb,5,7,12a,12b) gjennom hvilken en gass eller væske må passere, ved bruk, når det resiprokerende pumpeelementet (4,14) beveger seg mot henholdsvis den første posisjonen og den andre posisjonen.
2. En pumpe ifølge krav 1, hvor det minst ene fluidstrømsbegrensende elementet (10) omfatter et begrensende legeme (10a, 10b), og minst en del av det begrensende legemet har en gradvis minskende omkrets i et tverrsnitt som er parallelt med et tverrgående tverrsnitt av fluidstrømspassasjen
3. En pumpe ifølge krav 2, hvor den gradvis minskende omkretsen til det begrensende legemet (10a, 10b) minsker i en retning mot fluidstrømspassasjen (1 la, 1 lb).
4. En pumpe ifølge hvilket som helst av de forutgående krav, hvor det resiprokerende pumpeelementet omfatter et stempel (4), anordnet i en boring, eller en membran (14).
5. En pumpe ifølge hvilket som helst av de forutgående krav, hvor det fluidstrømsbegrensende elementet er koblet til det resiprokerende pumpeelementet.
6. En pumpe ifølge krav 4, hvor det fluidstrømsbegrensende elementet omfatter stempelet.
7. En pumpe ifølge hvilket som helst av de forutgående krav, hvor dempemidlene omfatter minst ett elastisk element (13) som tilveiebringer en økende motstand mot bevegelsen til det resiprokerende pumpeelementet når det resiprokerende pumpeelementet nærmer seg henholdsvis den første og/eller den andre posisjonen.
8. En pumpe ifølge krav 7, hvor det minst ene elastiske elementet er en fjær (13) som har minst en ende festet til en indre overflate til den første eller andre fluidseksjonen, eller til det resiprokerende pumpeelementet (4).
9. En pumpe ifølge hvilket som helst av de forutgående krav, omfattende minst en ventil for å kontrollere trykket til drivfluidet i den første fluidseksjonen (2).
10. Et pumpesystem omfattende minst tre pumper ifølge hvilket som helst av de forutgående krav.
11. Pumpesystemet ifølge krav 10, hvor hvert av innløpene/utløpene (5) for et drivfluid er koblet til en drivfluidfordelingsventil (18), og hver av innløpene (6) for en væske er koblet til et felles innløpsrør (19) og hver av utløpene (7) for en væske er koblet til et felles utløpsrør (20), hvor drivfluidfordelingsventilen (18) er anordnet for drive pumpene med overlappende sekvenser.
