Abstract
A waste gate valve for a turbocharger is provided that improves control responsivity, wear resistance and the flow uniformity of diverted exhaust gas by improving the operational structure thereof. The waste gate valve includes a turbine housing in which a portion of a bypass passage is formed along the inner circumferential surface of a discharge passage. A mixer ring includes bypass apertures therein that are arranged along the bypass passage formed in the inner circumferential surface of the discharge passage. Additionally, a control valve is configured to open or close the bypass apertures based on movement thereof.

A waste gate valve for a turbocharger, comprising:
- a turbine housing that accommodates a turbine wheel therein and includes a bypass passage formed therein to divert exhaust gas introduced into the turbine wheel to a discharge passage, a portion of the bypass passage being formed along an inner circumferential surface of the discharge passage;
- a mixer ring formed to block a region between the bypass passage and the discharge passage and including therein bypass apertures arranged along the bypass passage formed in an inner circumferential surface of the discharge passage;
- and
- a control valve configured to switch a state of the bypass apertures to an open state or a closed state via movement thereof to regulate an opening degree of the bypass apertures.
