Definitions
- This invention relates to a portable air/gas compressor capable of compressing air/gas.
- 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.
- this invention relates to compressors which are compact, lightweight, portable and/or mechanically non-complex, hi certain embodiments, this invention relates to compressors useful in conjunction with portable pneumatic power supplies (e.g., for powering pneumatic tool systems).
- 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).
- their 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).
- the present inventor has addressed the aforementioned problems and drawbacks in his U.S. Patent 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.
- 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.
- 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.
- this invention provides: an air/gas compressor comprising: a motor operably connected to a flywheel and capable of rotating the flywheel; 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; 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; 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
- this invention provides: a high pressure air/gas compressor employing a single, linearly actuated pump comprising: a motor operably connected to a flywheel and capable of rotating the flywheel during motor operation; 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; 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 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
- the counterweight assists in effecting a completion of the push stroke and during a pull stroke of the piston, the counterweight adds resistance to effecting a completion of the pull stroke.
- the position and location of the counterweight causes the counterweight, during directional motion of the flywheel, to alternately assist and resist push and pull strokes of the piston thereby to effect a generally consistent rotational velocity of the flywheel during compressor operation.
- the system is provided with a linearly actuated pump which includes a coolant fluid path through which a coolant can be transmitted thereby to temperature regulate the linearly actuated pump during operation.
- the coolant fluid path is a fluid passageway located internal to the shell housing in proximity to the linearly extendable and retractable piston.
- the system further includes a coolant reservoir in fluid communication with the coolant fluid path and a coolant pump for transmitting coolant from the coolant reservoir and through the coolant fluid path.
- such compressors are capable of filling an air storage reservoir to pressures of at least 500 psi, more preferably at least 1500 psi, still more preferably at least 3000 psi, and most preferably to pressures selected from between at least 0 and 5000 psi.
- such compressors are capable of filling an air storage reservoir to pressures selected from between 0 and 10,000 psi or more.

- Fluid as is used herein in the specification and claims is intended to retain its accepted art and/or scientific definition.
- the term “fluid” includes gases within its scope (in addition to liquids) and, therefore, a component described as being in fluid communication (or in fluid connection), is, in some circumstances, in gas-flow communication (or in gas-flow connection).
- Air/gas as used herein in the specification and claims is defined as a fluid in a gaseous state having neither independent shape nor volume.
- air/gas includes within its scope atmospheric air, purified atmospheric air, purified nitrogen, various ratios of mixtures of nitrogen and oxygen and other such fluids in the gaseous state not otherwise specifically described herein.
- compressor 101 generally comprises a frame 103 housing a motor 105 and drive assembly 107 which operates a piston driven pump 113 for compressing air inspired or input into the compressor system (e.g., from the surrounding atmosphere). More specifically, in the embodiment which is illustrated, motor 105, when operated, drives a small pulley 109 (e.g., approximately 2 inches in diameter) which, in turn, drives flywheel 111 (e.g., approximately 10 inches in diameter) which is connected to pulley 109 by a drive belt 115.
- motor 105 when operated, drives a small pulley 109 (e.g., approximately 2 inches in diameter) which, in turn, drives flywheel 111 (e.g., approximately 10 inches in diameter) which is connected to pulley 109 by a drive belt 115.
- flywheel 111 e.g., approximately 10 inches in diameter
- linearly actuated pump 113 is connected at its first end, via a conventional pivot type connection, to a shaft 117 extending from a lateral surface of flywheel 111 located at a select distance from the center or rotational axis of the flywheel (e.g,. here, where employing a 10 inch diameter flywheel, shaft 117 is located approximately 3.0 inches from the axis/center thereof).
- pump 113 is connected, also via pivot type (or rocker type) connection, to mount member 119 (e.g., immovably attached to frame 103).
- piston 121 of pump 113 is caused to alternate between generally linear push and pull strokes to effect a pressurization of air (i.e., in a compression chamber in pump 113, not shown). More specifically, in a "pull stroke", piston 121 is withdrawn from shell housing 123 (of pump 113) upon which air is inspired into the compression cavity of the pump (e.g., at air/gas input 125). Conversely, in a "push stroke", piston 121 is driven into shell housing 123 upon which air is pressurized in the compression cavity and thereafter expired via air/gas output 127 (e.g., for subsequent transmission to a filtration system).
- a counterweight 129 (shown in "phantom” or dotted lines) is integrated into flywheel 111 such as by molding, casting, machining, or other conventional tooling methods or mechanisms (alternatively, counterweight 129 can be affixed to flywheel 111 as an separately manufactured part). More particularly, in the most efficacious embodiments, counterweight 129 (e.g., a 10.3 oz. counterweight as illustrated, or, more generally, a counterweight sized between approximately 6 and 16 oz. or between approximately 10-20 % of the flywheel's mass) is located directly opposite the flywheel mount location of pump 113 i.e., opposite shaft 117 on the other or opposite side of rotational axis "a" of the flywheel.
- counterweight 129 e.g., a 10.3 oz. counterweight as illustrated, or, more generally, a counterweight sized between approximately 6 and 16 oz. or between approximately 10-20 % of the flywheel's mass
- counterweight 129 is located as described so that it provides a counterbalance to the force or resistance imparted by pump 113 on the flywheel as push and pull strokes of pump 113 are effected by the directional rotation of the flywheel (thought of differently, counterweight 129, in part, adds momentum to the flywheel to propel its rotation against the resistance of a push stroke of piston 121 into pump 113).
- counterweight 129 adds momentum to the flywheel to propel its rotation against the resistance of a push stroke of piston 121 into pump 113.
- the resistance of the air/gas being compressed impedes the stroke of the piston and thus the rotation of flywheel 111 (thus tending to decrease the rotational speed of the flywheel).
- counterweight 129 is located such that gravity acts on the counterweight in a direction which is generally co- directional with the rotational direction of the flywheel (i.e., clockwise as shown in the figure). In this manner, the gravitational force on the counterweight aids in completion of the push stroke thereby minimizing or eliminating any decrease in rotational velocity which would otherwise occur.
- counterweight 129 is located so that gravity acts on the counterweight in a direction which is generally opposite the rotational direction of the flywheel.
- the position and location of counterweight 129 causes the counterweight, during directional motion of flywheel 111, to alternately assist and resist push and pull strokes of the piston thereby to effect a generally consistent rotational velocity of flywheel 111 during compressor 101 operation.
- the aforementioned drawbacks related to mechanical reliability and/or upper limit operational speeds are substantially eliminated or at least ameliorated.
- at least one prototype of a compressor such as described herein has produced end pressures as high as approximately 5000 psi (and still higher pressures, e.g., above 6000 psi, or, possibly, even above 10,000 psi, are expected to be achieved through further optimization and/or experimentation) .
- a counterweight such as 129
- a flywheel with increased mass as compared to a conventional flywheel could be utilized.
- the increased momentum achieved by the use of a high mass flywheel should, in theory, substantially overcome the resistance of piston 121 as it compresses the air/gas (moreover, the lack of resistance during a "pull stroke" would not be comparatively sufficient, relative to the high mass flywheel, to impart significant increased rotational velocity).
- a sufficiently massed flywheel should not experience significant/detrimental changes in velocity due to resistance and non-resistance of piston 121 during push and pull strokes, respectively.
- compressor 101 employ filtration systems comprising one or more filter types such as for drying and/or cleaning air/gas (or, in certain embodiments employing so-called molecular sieves, isolating one gas molecule type from another).
- filter types such as for drying and/or cleaning air/gas (or, in certain embodiments employing so-called molecular sieves, isolating one gas molecule type from another).
- filtration system 135 generally comprises a filter column constructed from a combination of a desiccant filter 137 and a coalescent filter 139. More specifically, desiccant filter 137 is in fluid communication (i.e., gas-flow communication) with air/gas pump output 127 via a valve 144 connected to air/gas pump output line 128 (e.g., conventional high pressure tubing). Moreover, coalescent filter 139 is connected physically and fluidly (i.e., in gas-flow communication) in series with desiccant filter 137.
- Coalescent filter 139 is physically and fluidly connected to one end of air/gas output line 141 which is connected at its other end to manifold 147 (which includes a fill port 151 for connecting to and filling/pressurizing an air/gas vessel
- the entire filter system is generally hermetically sealed but permits air/gas flow through its connections to line 128 and line 141 and selectively via vent port 145 as desired (as will be described in the text which follows).
- compressor 101 when compressor 101 is operated to manufacture pressurized air/gas, such air/gas is flowed through both desiccant filter 137 and coalescent 139 at generally full system pressures.
- condensation e.g., water condensation
- particulate matter is filtered from the air/gas flowed through the filter system (e.g., thus resulting in clean, dry air/ gas).
- a vessel 3 is first connected to fill port 151 via a conventional or proprietary valve type connection.
- compressor 101 is powered on (e.g., by operation of on/off switch 131) and air/gas is inspired and compressed as compressor 101 's systems operate pump 113 as described above.
- the compressed air/gas flows from pump 113 through air/gas outlet 127.
- the compressed or pressurized air/gas is caused to first flow through desiccant filter 137 which removes moisture from the compressed air/gas, and, afterwards, through coalescent filter 139 which removes certain types of particulates.
- compressor 101 additionally includes an auto-shut-off switch (not shown) which functions to shut down compressor 101 upon detection of a pre-selected pressurization or fill pressure.
- auto-shut-off switch (not shown) which functions to shut down compressor 101 upon detection of a pre-selected pressurization or fill pressure.
- pressure gauge 143 (see Fig. 2) monitors the pressure of the air/gas being provided and automatically turns off compressor 101 (e.g., by switch relay) once the desired air/gas pressure is reached (e.g., which has been pre-selected by a compressor operator utilizing a pressure selection switch or dial, not illustrated).
- compressor 101 is able to automatically provide desired fill pressures (e.g., commensurate with storage and/or safety limits of particular air/gas storage vessels) without requiring that a pressure gauge be actively or constantly monitored.
- desired fill pressures e.g., commensurate with storage and/or safety limits of particular air/gas storage vessels.
- compressor 101 is shut down either automatically as described immediately above, or manually by operation of switch 131. Thereafter, before disconnecting vessel 3 from fill port 151, vent port 145 (e.g., operated by thumbscrew or similar mechanical mechanism) is opened and residual pressurized air/gas purges from the vent port and simultaneously causes the desiccant and coalescent filters to purge collected/filtered condensation and particulate matter, respectively.
- vent port 145 e.g., operated by thumbscrew or similar mechanical mechanism
- coolant system 201 generally includes a coolant reservoir 205 storing a liquid or gaseous coolant of conventional composition (e.g., an "anti-freeze" type liquid), a pump 203 (e.g., a conventional water pump) for pumping coolant from the reservoir and through the coolant system, and a radiator 215 for removing absorbed/adsorbed heat from the coolant fluid/gas prior to returning the coolant to coolant reservoir 205 by return path 213.
- a liquid or gaseous coolant of conventional composition e.g., an "anti-freeze" type liquid
- pump 203 e.g., a conventional water pump
- radiator 215 for removing absorbed/adsorbed heat from the coolant fluid/gas prior to returning the coolant to coolant reservoir 205 by return path 213.
- coolant fluid (or gas) is first drawn from reservoir 205 into and through internal conduits of pump 203 and then, afterwards, flowed into pump 113 via coolant ingress line 207.
- coolant As coolant enters pump 113, it circulates within shell housing 123 along the length of and proximal piston 121 (e.g., via a conduit circumferentially surrounding piston 121) thereby absorbing/adsorbing heat generated by the piston during pump 113 operation.
- the coolant After circulating within the internal components of pump 113, the coolant is then caused to exit or flow from pump 113 (by continued operation of pump 203) via coolant egress line 211 whereby it is transmitted to radiator 215 (e.g., of conventional radiator construction). After passing through radiator 215 where heat "carried" by the coolant is substantially removed or reduced (e.g., actively or passively), the coolant is returned to reservoir 205 via coolant return path 213 (e.g., for recirculation through the coolant system).
- radiator 215 e.g., of conventional radiator construction
- coolant return path 213 e.g., for recirculation through the coolant system.
- Alternative methods and mechanisms for cooling pump 113 during operation are, of course, envisioned.
- compressor 101 is believed to be particularly advantageous when used in combination with portable pneumatic power systems such as described in my United States Patent No. 6,932,128, compressor 101 is capable of producing clean, dry compressed air/gas for many other end uses. Moreover, compressors such as described herein exhibit significant performance improvements over known compressors. In this regard, compressor 101 is capable of filling large air/gas supply vessels with high air/gas pressures all the while having a heretofore unknown compact and simple structural design. In particular, compressor 101's compact and lightweight structure allows it to be uniquely portable for a compressor with such high performance compression capabilities. Furthermore, certain embodiments of compressor 101, relative to known compressors, are remarkably simply in structural design.
- compressor 101 utilizes a single drive belt 115 to minimize maintenance and extend longevity, does not require the changing and discarding of oil, does not require gas, oil, or filters, and/or generally uses no parts which are vulnerable to rusting or degradation.
- Certain additional embodiments (alternatively, or in combination with the immediately previously described improvements), exhibit low operational noise levels (typically about 55 dBA or less), are virtually maintenance-free, operate on standard power/electrical sources (e.g., 110-volt electrical power), do not emit toxic fumes or exhaust, and/or are self-cleaning (e.g., because moisture and dust particles are purged from the system at the conclusion of each use such as described above).
