Patent number: 6772674Abstract: An apparatus and method are provided for adjusting the axial distance between the front and rear walls of a vacuum booster, from outside of the booster, after the booster has been assembled. The booster includes a housing having a front housing and a rear housing joined together and defining a longitudinal axis of the booster. The front housing defines a front wall of the housing and an inner surface of the front wall. The rear housing defines a rear wall of the housing and includes a captive nut having threads adapted for threaded engagement with a threaded end of a tie rod. The front and rear walls are spaced an axial distance from one another along the longitudinal axis. A tie rod extends axially through the housing and has a first end engaging the rear wall of the housing and a second end engaging the front wall of the housing. The first end of the tie rod has threads for engaging the threads of the captive nut in the rear wall of the housing.Type: GrantFiled: November 12, 2002Date of Patent: August 10, 2004Assignee: Delphi Technologies, Inc.Inventors: Michael A. Kasselman, Michel J. Vermoesen, Patrick T. MacLellan
