Abstract
Apparatus for washing the blades of the high-pressure compressor of a two-stage turbo-compressor. A spray tube is mounted radially outwardly of an aperture defined in the turbine casing, but is capable of being moved radially inwardly through the aperture so as to direct an axial stream of wash water into the high-pressure compressor in response to the build-up of water pressure in a supply line which acts upon a piston against the action of a spring. In the absence of water pressure, the spring maintains the spray tube in its normal position externally of the casing.
