Abstract (en)
[origin: EP0318189A2] A scroll compressor is disclosed in which either or both of the spiral wraps (24,30) of the scroll members are reduced in thickness (i.e., cut away) (A, E) adjacent to the inlet port (34) defining the starting point the vanes would theoretically sealingly engage one another to initiate compression. Additionally, either or both of the spiral wraps of the scroll members may be reduced in thickness (J-K, L-M) (i.e. cut away) adjacent to the discharge port where the vanes separate and the compression chambers defined thereby communicate with the discharge port. Provision of a smooth transition (C-B) at the points of engagement cooperates to reduce noise and wear during operation of the compressor.
