Patent number: 6823884Abstract: A process for increasing or reducing the internal pressure of at least one hollow body (HK—1, HK—2, HK—3) to a specified set internal pressure. The set internal pressure is adjusted so that several pressure-increasing steps or pressure-reducing steps are conducted successively until the internal pressure deviates from the set internal pressure at most by a specified tolerance. Each of these steps brings about a pressure increase or pressure reduction the amount of which is not larger than a specified upper limit. In this way, impairments of comfort owing to the rise in pressure or the reduction in pressure are especially avoided. The actual internal pressure is only measured at the beginning of the process. In one design of the invention, this amount depends upon the volumes of the hollow bodies (HK—1, HK—2, HK—3) and a supply line (VL) as well as (in the case pressure is increased) from the pressure which a pressure generator generates.Type: GrantFiled: January 24, 2003Date of Patent: November 30, 2004Assignee: DaimlerChrysler AGInventors: Christoph Kern, Wolfram Schroeder, Daniel Schulz
