Apparatus and method for using a lightweight portable air/gas power supply
ActiveUS6932128B2Easily and quickly refilledHigh pressure levelTravelling sacksLiquid fillingFiberMulti-valve
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.

ActiveUS8434524B2Less spaceLight weightFlexible wall reciprocating enginesPump assembliesStored energyEngineering
The invention is a combination accumulator and reservoir which stores energy when the accumulator deforms from its original shape in response to the flow of a pressurized fluid from the reservoir. The stored energy is returned when the fluid flow is reversed and the accumulator discharges the fluid and returns to its original shape. At least one part of the novelty of the invention is that the accumulator and the fluid reservoir reside in the same housing such that the volume of each varies inversely. Accordingly, the invention is more compact and weighs less than conventional accumulators. Another feature of the invention is that fluid is located around the bladder accumulator to lubricate contact between the bladder and sides of the reservoir.
