Claims (2)

1. Excenterpump som omfattar en med vinglober f ör-sedd ring (12) som inifrän är i ingrepp med en rotor (16) 5 som är försedd med vinglober, vilken rotor uppvisar färre vinglober än ringen, varvid ringen och rotorn är roterbara runt parallella axlar (14, 18) i ett cylinderaktigt utrym-me i pumpens stomme (10), varvid nämnda stomme uppvisar fasta in- och utlopp (20, 22), vilka är axialt anordnade i 10 förhällande till ringen för att släppa ett medium till pumpens driftskamrar (30 - 38) och släppa ut detsamma frän driftskamrarna (30 - 38), vilka är anordnade mellan rotorn (16) och ringen (12), varvid rotorns och ringens vinglober är spiralformat vridna i längdriktningen, k ä n n e -15 tecknad av att in- och utloppen (20, 22) är symmet-riskt anordnade till det plan som omfattar rotorns (16) axel (18) och ringens (12) axel (14), varvid de bäda öpp-ningarna (20, 22) är anordnade till den axiala änden av samma rotor (16) och ring (12), och att vridningsvinkeln 20 är sädan att den ena änden av varje vinglob ligger i en fasdifferens pä 5° - 15° till den andra änden av samma vinglob.
2. Excenterpump enligt patentkrav 1, k ä n n e -tecknad av att fasdifferensen är i storleksklassen : 25 10°.
