Portable air/gas compressorPortable air/gas compressor description/claimsThe Patent Description & Claims data below is from USPTO Patent Application 20070212236, Portable air/gas compressor. Brief Patent Description - Full Patent Description - Patent Application Claims
RELATED APPLICATION DATA [0001]This application claims the benefit of priority of U.S. Provisional Patent Application No. 60/780,236, entitled GAS COMPRESSOR and co-invented herewith and hereby incorporates such application, in its entirety, by reference. U.S. Pat. No. 6,932,128, entitled APPARATUS AND METHOD FOR USING A LIGHTWEIGHT PORTABLE AIR/GAS POWER SUPPLY and co-invented herewith, is further incorporated in its entirety by reference. FIELD OF INVENTION [0002]This invention relates to a portable air/gas compressor capable of compressing air/gas. In at least one embodiment, this invention relates to compressors capable of producing clean, dry, compressed air/gas (e.g., either in naturally occurring atmospheric nitrogen/oxygen ratios or as purified nitrogen or in alternative ratios therebetween) employing atmospheric air as a starting material. In at least one additional embodiment, this invention relates to compressors which are compact, lightweight, portable and/or mechanically non-complex. In certain embodiments, this invention relates to compressors useful in conjunction with portable pneumatic power supplies (e.g., for powering pneumatic tool systems). BACKGROUND OF THE INVENTION [0003]A tremendous variety of tools types and the like have been developed over the centuries to address the many numbers of construction and manufacturing arts which have evolved during civilization's technological progress through modern times. For example, in a single industry such as the construction industry, dozens of different tools types may be used on a single construction site. In particular, the number of such tool types which are used has increased due to the various specialties and sub-specialties of carpentry and other construction techniques which continue to develop as modern buildings become more complex. [0004]Throughout the modern evolution of tools, substantial efforts have been made to automate tool operation, principally, to improve job efficiencies by improving tool operation speeds and by reducing fatigue of tool operators. In recent decades, such automation efforts have typically involved the development or innovation of compressor powered pneumatic tools or tools powered by electricity. In this regard, due to their improved efficiencies, the use of automated tools has become so commonplace that one would be hard-pressed to not find a pneumatic nail gun or an electrically powered drill at a typical construction job site. Nevertheless, conventional pneumatic or electrically operable tools suffer various disadvantages or drawbacks. [0005]For example, pneumatic or electrically powered tools which are directly connected to a compressor via a hose or to an electrical outlet via a power cord are limited in their portability or mobility due to their attachment to their respective power sources (e.g., their portability is limited to the length of the hose or cord and/or they may be difficult or unsafe to carry up a ladder for example). Moreover, the longer the cord or hose, the greater the overall weight as well as the chance that such hose or cord will become entangled or otherwise act as a safety hazard (e.g., as a tripping hazard). Although battery operated tools address some of these disadvantages, such tools are burdened by their own drawbacks such as their increased weight and reliance on the finite charge of a battery (and, after battery depletion, one must wait for the battery to be recharged or have additional batteries available, for example). [0006]The present inventor has addressed the aforementioned problems and drawbacks in his U.S. Pat. No. 6,932,128, entitled APPARATUS AND METHOD FOR USING A LIGHTWEIGHT PORTABLE AIR/GAS POWER SUPPLY. The present invention is intended to further improve on the apparatus and methods disclosed therein. [0007]In addition to the aforementioned problems related to portability and mobility of pneumatic tools such as discussed above, such tools' reliance on the use of conventional air compressors for providing pneumatic air "power" further compounds their drawbacks. In this regard, known compressors are generally bulky and heavy and exhibit other related drawbacks. More specifically, known air compressors are too large and unwieldy to safely use in many work environments (e.g., on a rooftop in a construction project). Moreover, known compressors are noisy, complicated in mechanical structure and/or expensive to maintain or manufacture, or cannot safely pressurize air/gas past certain threshold "psi's". Certain other known compressor types utilize fossil fuels for power, require the use of oil (for lubrication), and/or employ disposable filters. In this regard, such known air/gas compressor types are environmentally unsound as they either produce significant pollution or they rely on finite natural resources for fuel, or both. [0008]In view of the above, it is apparent that there exists a need in the art for methods and/or apparatus and/or systems which overcome or, at least, ameliorate one or more of the above or other drawbacks. It is a purpose of this invention to fulfill this need, as well as other needs in the art which will become apparent to the skilled artisan once given the above disclosure. SUMMARY OF THE INVENTION [0009]Generally speaking, this invention fulfills the above-described needs in the art by providing: compressors, with or without filtration and/or cooling systems, which are compact, lightweight, portable and/or mechanically non-complex. [0010]In at least one embodiment, this invention provides: [0011]an air/gas compressor comprising: [0012]a motor operably connected to a flywheel and capable of rotating the flywheel; [0013]a linearly actuated pump having a first end and a second end, the first end pivotally connected to the flywheel at a pump mount location and the second end pivotally connected to a frame member, the pump including a piston which is linearly actuated when the flywheel is caused to rotate; [0014]a counterweight connected to the flywheel at a location on the flywheel generally opposite the pump mount location, the counterweight being so located such that when the flywheel is caused to rotate, the counterweight imparts momentum to the flywheel; [0015]the linearly actuated pump including an air/gas pump input for receiving air/gas and an air/gas pump output for outputting air/gas which is pressurized by the linearly actuated pump when the piston is linearly actuated. [0016]In an alternative embodiment, this invention provides: a high pressure air/gas compressor employing a single, linearly actuated pump comprising: [0017]a motor operably connected to a flywheel and capable of rotating the flywheel during motor operation; [0018]a single, linearly actuated pump having a first end and a second end, the first end pivotally connected to the flywheel at a pump mount location and the second end pivotally connected to a frame member, the pump including a piston which is linearly actuated to compress air/gas in an air/gas compression chamber when the flywheel is caused to rotate by the motor operation; [0019]the linearly actuated pump including an air/gas pump input for inspiring gas at an initial input pressure and an air/gas pump output for expiring gas at a pressure increased relative to the initial input pressure; and [0020]wherein the single, linearly actuated pump, operated by the flywheel and motor combination, is capable of independently powering pressurization of air/gas up to pressures of at least 500 psi, more preferably at least 1500 psi, and most preferably at least 3000 psi.
