TWO-STAGE FUEL ATOMISER, COMBUSTION CHAMBER EQUIPPED WITH SUCH ATOMISER, AND GAS TURBINE EQUIPPED WITH SUCH CHAMBER Russian patent published in 2012 - IPC F02C7/22 

FIELD: engines and pumps.

SUBSTANCE: two-stage fuel atomiser includes two valves located one after another, which are set separately to closed positions, two fuel supply lines and internal housing. One of those valves, which is called primary valve, is installed in primary fuel flow line, and the second valve called secondary is located in secondary fuel flow line. One of the fuel supply routes is called primary line, and the other one - secondary line. Secondary line ends after primary valve. Secondary valve slides in internal housing and internal housing restricts primary line. Secondary line passes through central hole of secondary valve. At least one slot goes through secondary valve in radial direction in the section between its periphery and central hole. Two-stage fuel atomiser includes at least one hole crossing internal housing in the section between primary fuel flow line and secondary valve and connected to the slot when secondary valve (10) is in closed position.

EFFECT: invention is aimed at modifying the existing atomisers instead of their being designed anew.
