Title: Turbocharger waste gate brake and system therefor

Abstract

A device comprising: a housing defining a chamber and having a first opening into the chamber; a shaft having two ends, one end extending exteriorly of the housing and the other end interiorly in the chamber, the other end being linearly movable progressively into and out of the chamber, the shaft moveable in response to forces exerted on the one end; first means for defining a magnetic path, for generating an electromagnetic force in such path and for preventing the shaft from moving, comprising ferromagnetic means, forming part of the magnetic path and being positioned within the chamber, the ferromagnetic means being coupled to the other end of the shaft; and an electromagnetic assembly means positioned within the chamber and spaced apart from the ferromagnetic means in an unlocked position, for generating the magnetic force in response to an operating parameter, the electromagnetic means being slidably movable in the chamber in response to the magnetic force, into locking engagement with the ferromagnetic means to lock the ferromagnetic means in place and hence lock the shaft at its then current position corresponding to a condition of the operating parameter.
