A jet pump apparatus for mixing a higher pressure gas and a lower pressure gas, includes an inlet section, an outlet section, a diffuser section and a mixing section. Inlet section includes a higher pressure inlet and a lower pressure inlet. Mixing section includes a plurality of separated mixing chambers. The diffuser section includes diffusers for receiving mixed gases from the mixing chambers. The outlet section receives mixed gases from the diffuser section and conveys those gases to an outlet. The inlet section includes a higher pressure inlet which receives higher pressure gas, and a lower pressure gas inlet which receives lower pressure gas. Each of the mixing chambers has a primary nozzle for introducing primarily higher pressure gas from to a respective mixing chamber, and a secondary inlet for introducing primarily lower pressure gas to each of the mixing chambers.
A jet pump apparatus for mixing a higher pressure gas from a higher pressure gas supply and a lower pressure gas from a lower pressure gas supply, the apparatus including an inlet section, an outlet section, a diffuser section and a mixing section, the inlet section including a higher pressure gas inlet and a lower pressure gas inlet, the mixing section including a plurality of separated mixing chambers, and the diffuser section including diffusers for receiving mixed gases from each of the mixing chambers, and the outlet section for receiving mixed gases from the diffuser section and conveying the mixed gases to a mixed gas outlet, and the inlet section including a higher pressure gas inlet duct which receives higher pressure gas from the higher pressure gas inlet, and a lower pressure gas inlet duct which receives lower pressure gas from the lower pressure gas inlet, and for each of the plurality of mixing chambers, there being a primary nozzle for introducing primarily higher pressure gas from the higher pressure gas inlet duct axially into a respective mixing chamber, and there being a secondary inlet for introducing primarily lower pressure gas from the lower pressure inlet duct axially into each of the mixing chambers, the higher pressure gas being derived from a compressor section of a gas turbine engine.
A compressed gas supply system including a jet pump apparatus for mixing a higher pressure gas from a higher pressure gas supply and a lower pressure gas from a lower pressure gas supply, the apparatus including an inlet section, an outlet section, a diffuser section and a mixing section, the inlet section including a higher pressure gas inlet and a lower pressure gas inlet, the mixing section including a plurality of separated mixing chambers, and the diffuser section including diffusers for receiving mixed gases from each of the mixing chambers, and the outlet section for receiving mixed gases from the diffuser section and conveying the mixed gases to a mixed gas outlet, and the inlet section including a higher pressure gas inlet duct which receives higher pressure gas from the higher pressure gas inlet, and a lower pressure gas inlet duct which receives lower pressure gas from the lower pressure gas inlet, and for each of the plurality of mixing chambers, there being a primary nozzle for introducing primarily higher pressure gas from the higher pressure gas inlet duct axially into a respective mixing chamber, and there being a secondary inlet for introducing primarily lower pressure gas from the lower pressure inlet duct axially into each of the mixing chambers, the higher pressure gas being derived from a compressor section of a gas turbine engine.
An aircraft which includes a compressed air supply system including a jet pump apparatus for mixing a higher pressure gas from a higher pressure gas supply and a lower pressure gas from a lower pressure gas supply, the apparatus including an inlet section, an outlet section, a diffuser section and a mixing section, the inlet section including a higher pressure gas inlet and a lower pressure gas inlet, the mixing section including a plurality of separated mixing chambers, and the diffuser section including diffusers for receiving mixed gases from each of the mixing chambers, and the outlet section for receiving mixed gases from the diffuser section and conveying the mixed gases to a mixed gas outlet, and the inlet section including a higher pressure gas inlet duct which receives higher pressure gas from the higher pressure gas inlet, and a lower pressure gas inlet duct which receives lower pressure gas from the lower pressure gas inlet, and for each of the plurality of mixing chambers, there being a primary nozzle for introducing primarily higher pressure gas from the higher pressure gas inlet duct axially into a respective mixing chamber, and there being a secondary inlet for introducing primarily lower pressure gas from the lower pressure inlet duct axially into each of the mixing chambers, the higher pressure gas being derived from a compressor section of a gas turbine engine, and the aircraft including a downstream apparatus which receives a pressurised gas supply from the compressed air supply system, the downstream apparatus including at least one of an on-board oxygen generating system and an air conditioning system.
