Internal combustion engine having coaxially mounted compressor, combustion chamber, and turbine

Claim 1

A compressor adapted for use in an internal combustion engine comprising an axially disposed, tubular housing, a first outer radial wall having an axial inlet therein, a second outer radial wall affixed to and projecting radially from one end of said housing and having an axial outlet communicating directly with said housing, a peripheral axial wall connecting said first and second outer radial walls and forming therewith a cylinder which is concentric with said housing, but which has a substantially larger diameter, and an inner radial wall mounted intermediate said first and second outer radial walls and of smaller diameter than said outer radial walls, whereby the periphery thereof is uniformly spaced from said peripheral axial wall, and a spiral web intermediate said first outer wall and said inner wall having its edges affixed to said walls, cooperating to define a spiral chamber, said inner radial wall and said second outer radial wall cooperating to define a radial duct communicating with said housing through said axial outlet, and said spiral chamber communicating at its innermost end with said inlet and at its outermost end with said radial duct, the sole communication between said inlet and said housing being through said spiral chamber, said radial duct, and said axial outlet, and bearing means for supporting said compressor for rotation about its axis.
