US Patent:

6772674, Aug 10, 2004
Filed:

Nov 12, 2002
Appl. No.:

10/292733
Inventors:

Michael A. Kasselman - West Chester OH
Michel J. Vermoesen - Miamisburg OH
Patrick T. MacLellan - Dayton OH
Assignee:

Delphi Technologies, Inc. - Troy MI
International Classification:

F01B 1102
US Classification:

921693, 91379 R
Abstract:

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. The second end of the tie rod has an axially facing surface thereof for applying an axially directed force against the inner surface front wall of the housing.

Assignee:

Delphi Technologies, Inc. - Troy MI
International Classification:

F15B009/10
US Classification:

91376R
Abstract:

The present invention includes a system for providing an improved controlled airflow within a vacuum booster system. The system includes a vacuum booster assembly having a primary chamber and a secondary chamber, and an outer tube having a first end and a second end, the first end in communication with the secondary chamber of the vacuum booster assembly. The system additionally includes an airflow control assembly operably coupled to the second end of the outer tube, and an inner tube, concentric to the outer tube, having a first end and a second end, the first end operably coupled to the airflow control assembly, the second end in communication with the primary chamber of the vacuum booster assembly. In the system, air flows from the primary chamber of the vacuum booster assembly to the airflow control assembly within the inner tube and air flows from the airflow control assembly to the secondary chamber of the vacuum booster assembly within the outer tube.
