Abstract
A rotary fluid handling device, such as a turbine or a compressor, comprising a stationary body and a rotor rotatably mounted therein. The rotor has a flowway therethrough having a radially extending end. An annular seal coaxially surrounds the rotor within the stationary body axially distal the radially extending flowway end. The device further comprises a bypass passageway system having an inlet communicating with the area between the rotor and the stationary body on the axially opposite side of the seal from the radially extending flowway end and an outlet communicating with the flowway. The inlet opens at least partially radially outwardly into the stationary body.
Claims18
A rotary fluid handling device comprising:
- a stationary body;
- a rotor rotatably mounted in said stationary body, said rotor having at least one flowway therethrough, said flowway having an end portion extending substantially radially into said rotor;
- annular seal means coaxially surrounding said rotor, disposed within said stationary body, and axially spaced from said radially extending end of said flowway;
- and means defining a bypass passageway system having an inlet communicating with the area between said rotor and said stationary body on the axially opposite side of said seal means from said radially extending end of said flowway, said inlet opening at least partially radially outwardly into said stationary body, and an outlet communcating with said flowway, a first portion of said passageway system, including said outlet, comprising a rotor passage extending generally longitudinally through said rotor, and a second portion of said passageway system, including said inlet, comprising a stator passage extending through said stationary body.
A rotary fluid handling device comprising:
- a stationary body;
- a rotor rotatably mounted in said stationary body, said rotor having at least one flowway therethrough, said flowway having an end portion extending substantially radially into said rotor;
- annular seal means coaxially surrounding said rotor, disposed within said stationary body, and axially spaced from said radially extending end of said flowway;
- and means defining a bypass passageway system having an inlet communicating with the area between said rotor and said stationary body on the axially opposite side of said seal means from said radially extending end of said flowway, said inlet opening at least partially radially outwardly into said stationary body, a portion of said passageway system, including said inlet, comprising a stator passage extending through said stationary body and sized to prevent a fluid flow rate through said stator passage greater than the fluid flow rate through said seal means.
A rotary fluid handling device comprising:
- a stationary body;
- a rotor rotatably mounted in said stationary body, said rotor having at least one flowway therethrough, said flowway having an end portion extending substantially radially into said rotor;
- annular seal means coaxially surrounding said rotor, disposed within said stationary body, and axially spaced from said radially extending end of said flowway;
- and means defining a bypass passageway system having an inlet communicating with the area between said rotor and said stationary body on the axially opposite side of said seal means from said radially extending end of said flowway, said inlet opening at least partially outwardly into said stationary body, and wherein said passageway system is partially defined by a first surface inclined radially outwardly and axially toward said seal means adjacent the portion of said inlet closest to said seal means.
