Regulators, power supply systems and methods for using the same

Abstract

Regulators and / or parts or components thereof useful, for example, in systems for powering pneumatic tools. In certain embodiments, dual-stage regulators wherein each stage of the regulators is adjustable and / or tunable. In certain preferred embodiments, tunable and / or adjustable dual-stage regulators which are capable of being used, selectively as desired, in low and / or high pressure applications, shot-type and / or continuous flow delivery applications, and / or low and / or high volume applications (or any combination thereof). In certain additional embodiments, in combination with or separate from the features of other embodiments described herein, regulators which exhibit stable performance regardless of, for example, cylinder supply pressure.

Problems solved by technology

[0010] Additionally, with existing regulator designs, undesired pressure changes are often encountered during regulator operation

As an example of this shortcoming in existing regulator designs, as a high-pressure air source (for example, a cylinder or "gas cylinder" made of steel, aluminum, or carbon fiber) is depleted or the air supplied by that source or gas pressure decreases, the output pressure delivered by the regulator will usually increase (i.e., it is believed that this is because the initial pressure available in the low pressure chamber to deflect the low pressure piston is reduced, allowing the regulator seat to be closed by the regulator pin , so that the air flow delivered to the low-pressure chamber is stopped in good time)

This unintended consequence has caused problems in the operation of certain types of regulators, for example, when used in portable air power systems, because, for example, certain tool types can be damaged or Won't work properly (e.g. may drive the nail too deep)
