Abstract
An intermediate discharge port in a scroll compressor and a method for controlling part-load efficiency of a scroll compressor are disclosed. The compressor includes a compressor housing; a non-orbiting scroll member and an orbiting scroll member forming a compression chamber; a discharge port for receiving a compressed fluid; and an intermediate discharge port fluidly connected between the compression chamber and the discharge port, the intermediate discharge port including a sealing member, fluid flow being prevented between the compression chamber and the discharge port through the intermediate discharge port when in a flow-blocked state, and fluid flow being enabled between the compression chamber and the discharge port through the intermediate discharge port when in a flow-permitted state.
