Filed:

Sep 13, 2005

Appl. No.:

11/225389

Inventors:

Brian J. McGloughlin - Pittsfield Township MI, US
James M. Sute - Trenton MI, US
Peter M. Hannish - Shelby Township MI, US
Matthew L. Blaisdell - Canton MI, US
Nicholas P. Howell - Grosse Pointe Park MI, US

Assignee:

GM Global Technology Operations LLC - Detroit MI

International Classification:

B05B 9/06

US Classification:

239100, 239 11

Abstract:

The invention concerns a two-part spray application system and method for applying a two-part spray on an object. First and second pumps have outlets, with the pressure at each outlet monitored by pressure transducers. During the spraying process for each object, the pressure at the outlet of each pump must exceed a minimum threshold pressure at least once, or a fault condition is indicated. Such fault conditions may indicate a leak or disconnect in a hose downstream of the pumps.
