Patent number: 6932128Abstract: A lightweight carbon fiber air/gas supply vessel storing high pressure air/gas. The air/gas supply vessel output is controlled by an adjustable pressure reduction valve which varies output pressure from very high to low pressure levels. An alternative multi-valve system uses a first pressure reduction valve to reduce output pressure from the very high levels in the air/gas supply vessel to an intermediate pressure level, and a second pressure reduction valve that reduces the air/gas pressure from the intermediate level to a fine tunable low pressure level. In both embodiments, the output of the last pressure reduction valve used is connected to a high pressure cable which in turn uses a standard universal fitting which can be coupled to most pneumatically powered equipment. Additional high pressure reservoir vessels can be used to replenish the lightweight air/gas supply vessel when its supply of air/gas is depleted.Type: GrantFiled: June 28, 2002Date of Patent: August 23, 2005Assignee: Speed Air Systems, Inc.Inventor: Robert Lew Turan, Jr.
