Document Type and Number:
Japanese Patent JPH0784872
Kind Code:
B2
Abstract:
A gas removable pump for liquid comprising a housing (10) having an inlet (34) for introducing a liquid thereinto and an outlet (76) for feeding the liquid therefrom, a drive shaft (18) extending into the housing, a pump (22) disposed within said housing and secured to the shaft for co-rotatin therewith, the pump dividing in a liquid-tight manner the interior space of the housing into a suction side and a delivery side. A chamber (46) is confined around the shaft (18) within at least one of the suction side and the delivery side of the housing and is arranged to generate a vortical flow of the liquid introduced therein to thereby separate gas-rich liquid which gathers in an axially central portion of the chamber. A collecting space for collecting the liquid containing little gaseous contaminants is provided in at least one of the suction side and the delivery side radially outward of the chamber. The pump (22) further includes arrangements for introducing the liquid from the inlet into the chamber and for discharging the gas-rich liquid outside of the housing. The gas-rich liquid gathers around the shaft (18) and is discharged through a removal passage (92) and orifices formed (94,96) in the shaft.
