Compressed air or highpressure fluid for atomizing combustors branches pumped fluid portion via valves to piston pump coupled to compressor or highpressure pump.

摘要

Part of the fluid delivered by the pump (1) is branched off and used to drive a piston pump (12). This pump (12) is coupled to a compressor (17) or highpressure pump and in this way produces compressed air or highpressure fluid. Components in the flow include branch point tee-piece (5) and control valve (6) which uses an adjuster (7) to pass the branched fluid to the jet (8). The main flow is routed along pressure lines (10,11) to the piston pump (12) whose piston rod (15) is coupled to the compressor piston (16,17).
