ABSTRACT:
A gas removable pump for liquid comprising a housing having an inlet for introducing the liquid thereinto and an outlet for feeding the liquid therefrom, a drive shaft extending into the housing and a rotary pump disposed within the housing, the rotary pump including a rotor secured to the drive shaft 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 is provided for ejecting the gas-rich liquid separated in each cell through a passage formed in the drive shaft and the rotor. Also provided is a valve in the passage for opening and closing the same, the valve 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.
