Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
186 words
A compressor assembly comprising: a compressor casing having a substantially axially disposed gas inlet; an impeller supported for rotation within said casing about said axis and located to receive gas from said inlet, diametrically opposed points on said casing being equidistant from said axis; walls of said casing defining an annular vaneless difuser surrounding the radially outer end of said impeller to receive gas discharge therefrom, the radial dimension of said diffuser from said axis being substantially greater than the radius of said impeller; a plurality of circumferentially spaced conical diffusers associated with said casing having their smaller ends in gas communication with said vaneless diffuser, the outer ends of said conical diffusers providing an outlet for the gas from said impeller; walls defining a plenum connected to said casing enclosing said conical diffusers to receive the gas therefrom, the axial dimension of said plenum being substantially equal to the axial dimension of said casing; and an integral gas cooler located in said plenum and guide means about said circumferentially spaced conical diffusers for directing the discharge gas from said conical diffusers into said gas cooler.
Claim 2
Dependent Claim
186 words
A compressor assembly comprising: a compressor casing having a substantially axially disposed gas inlet; an impeller supported for rotation within said casing about said axis and located to receive gas from said inlet, diametrically opposed points on said casing being equidistant from said axis; walls of said casing defining an annular vaneless difuser surrounding the radially outer end of said impeller to receive gas discharge therefrom, the radial dimension of said diffuser from said axis being substantially greater than the radius of said impeller; a plurality of circumferentially spaced conical diffusers associated with said casing having their smaller ends in gas communication with said vaneless diffuser, the outer ends of said conical diffusers providing an outlet for the gas from said impeller; walls defining a plenum connected to said casing enclosing said conical diffusers to receive the gas therefrom, the axial dimension of said plenum being substantially equal to the axial dimension of said casing; and an integral gas cooler located in said plenum and guide means about said circumferentially spaced conical diffusers for directing the discharge gas from said conical diffusers into said gas cooler.
Claim 3
Dependent Claim
42 words
The compressor set forth in claim 1 and further comprising guide means including guide vanes located within said plenum adjacent the discharge from said conical diffusers and positioned to guide the gas discharged therefrom in the direction of the gas cooler inlet.
