Working principle of oil-gas separator:
The end cap of oilgas separator may channelize the flow and increase the flow rate. When oil flows from the pump outlet to the
separator, the sectional area gets smaller and smaller, and the flow rate gets higher and higher. Under the action of flow chann
elizing arc of end cap of the oilgas separator, liquid oil flows forward spirally down the inner wall of separator. The gas density
and centrifugal force is low, and fuel and gas are separated; the gasses are gradually built in the center, and the gasoil mixture is
discharged into the oil return chamber through the ventpipe subassembly. When the liquid oil is built up inside the oil return chamber
to a certain extent, the floater floats upward due to the effect of the buoyancy force and drives the valve core to move up, the float
valve is opened, and the liquid oil flows back to the pump intake.
