Abstract : This patent describes an air supply system for a recompression chamber which includes inlet and outlet conduits which extend through the chamber. The inlet conduit is adapted for connection to a pressurized air source and the outlet conduit serves as a vent of chamber air. A fluid amplifier is located within the chamber and is responsive to a primary fluid flow for sucking in and discharging a secondary fluid flow. The inlet conduit is connected to the fluid amplifier for supplying air from the pressurized air source as the primary fluid flow so that the chamber air is sucked in and is discharged as the secondary fluid flow through the fluid amplifier. A secondary conduit is connected in parallel with the outlet conduit and is adapted for connection to the pressurized air source. Valve means is connected in the secondary conduit for selective blow down or exhaust of the chamber so that the chamber can be quickly compressed or decompressed at the start or end of chamber use.
