Abstract
A screw compressor includes a housing having a discharge port; at least two rotors rotatably disposed in the housing for generating opposed discharge flows in radial and axial directions; and a tangential flow guide cusp disposed in the discharge port and at least partially defining a radial flow portion of the discharge port and having flow guiding surfaces arranged to guide tangential flows from said rotors so as to provide at least one of radial and axial directed flows.
Claims4
A screw compressor, comprising:
- a housing having a discharge port;
- at least two rotors rotatably disposed in said housing for generating opposed discharge flows in radial and axial directions;
- and
- a tangential flow guide cusp disposed in said discharge port and at least partially defining a radial flow portion of said discharge port and having flow guiding surfaces arranged to guide tangential flows from said rotors so as to provide at least one of radial and axial directed flows, wherein said flow guiding surfaces include radial flow guiding surfaces which converge to define a cusp point directed away from said rotors, and axial flow guiding surfaces which converge to define a cusp point directed toward said rotors.
