Beschreibung
Zusammenfassung:	A gas removable pump for liquid comprising a housing (10) having an inlet (34) for introducing the liquid thereinto and an outlet (62) for feeding the liquid therefrom, a drive shaft (24) extending into the housing and a rotary pump (22) disposed within the housing, the rotary pump including a rotor (30) secured to the drive shaft (24) for co-rotation therewith and a plurality of cells for feeding the liquid, each cell constituting a separator for gas -rich liquid upon rotation of the rotor. An ejector (82) is provided for ejecting the gas-rich liquid separated in each cell through a passage (70) formed in the drive shaft and the rotor. Also provided is a valve (108) in the passage (92, 94) for opening and closing the same, the valve (108) being arranged to operate in response to a pressure in the cell. The gas rich liquid gathers at inner portion of the cell due to a centrifugal force and is discharged by means of the ejector through the passage when the valve is in an open position.
