Abstract
An improved scroll type compressor having enlarged fixed and orbiting spiral element tips with parallel flat faces is disclosed. A discharge port for discharging compressed fluids is positioned in the fixed end plate. The discharge port is shaped to provide an opening that is effectively elongated adjacent the flat face of the fixed spiral element. In one preferred embodiment, the discharge port has a pair of elongated sides that extend in parallel with the flat face of the fixed spiral element. Another preferred embodiment the discharge port includes a plurality of holes arranged such that a common tangent to the perimeter of the holes is substantially parallel to the flat face of the fixed spiral element. A tapered surface may also be provided in the flat face of the enlarged tip of the orbiting spiral element to improve communication between the compression chamber and the discharge port.
