ABSTRACT:
A waste gate brake device (50,110,200) for controlling a waste gate (34) of a turbocharger (20) comprising: a housing (52, 112) defining a chamber (54;116) and first opening (58a,b;122) into the chamber; a shaft (60) adapted to be connected to and movable with the motion of a waste gate (34); a magnetically responsive plate or clamp (72; 140) interacts with an electromagnetic assembly (92; 130) within a common magnetic path in response to an electromagnetic force in such path and for preventing the shaft (60) from moving, thereby preventing the waste gate from moving.
