Abstract:
The present disclosure relates to an improved compressor comprising a plurality of cylinders housed within a common block such that these cylinders discharge their output to a common output. The compressor can comprise a plurality of motors such that each of the plurality of cylinders is powered by an independent motor, and compressor and motors make one compact and single unit. In an alternate embodiment, there can be a single common motor to power the plurality of cylinders through a common crank shaft and the common motor is positioned separate from the compressor. Also disclosed is an improved layout for refrigeration system wherein common motor of compressor is also used to power evaporator fan and condenser fan mounted on a common shaft through a pulley and belt arrangement.
Abstract:
A compressor unit (38) for supplying pressurized medium to a tire mounted on a vehicle wheel rim (34) is proposed, having a compressor (58) for exerting pressure on a fluid medium that is to be conveyed into the tire. The compressor unit (38) is dimensioned to be accommodated in a center bore (44) of the vehicle wheel rim (34) when the vehicle wheel rim (34) is in the mounted state on a wheel hub (62); and the compressor (58) can be driven by a drive unit (56) positioned in the vicinity of the center bore (44) of the vehicle wheel rim (34). A vehicle wheel rim (34) having a pressurized medium supply device (22) for a tire that is mounted on the vehicle wheel rim (34) is also proposed, as well as a vehicle having a vehicle wheel that includes such a vehicle wheel rim (34). A device for providing a vehicle wheel mounted energy supply is also proposed.
Abstract:
The present invention provides a system and method for economically using compressed air as automobile power source, comprising: a compressed air power device, which includes automobile air storage tubes (1) to store a sufficient amount of high-pressure compressed air and a cylinder-combined engine consisting of the first and second cylinders (9)(10), and which can make full use of the compressed air to produce driving power; a mechanism to produce, store and provide high-pressure compressed air, which includes a boiler-type high-pressure compressed air producing and storing device, abbreviated as boiler-type HCAPS device (4), to be able to use electricity during periods of low energy demand (off-peak) such as at night simultaneously recovering the by-produced heat for central heating, and pressurizing and inflating into the automobile air storage tubes (1) during daytimes; brake energy recovery and regeneration devices, which include a spring reserving-releasing device and/or a compressed air reserving-releasing device to save the compressed air in the automobile air storage tubes (1) for saving the driving power; an inner gear ring assembly, which includes an inner gear ring (2) gearing meshing with inner acting gears (45), with the first and second accelerating gears (72)(92), with a flywheel front inner meshing gear (48) and reset gears (46), for transmitting torque and mixing/outputting power; some clutch transmission devices and a controller, which controls orderly coordinated operation of devices and mechanisms.
Abstract:

Abstract:
A system (200) for enhancing a flow of a fluid induced by a rod pumping unit (100) is provided. A pumping control unit (212) is configured to control stroke movement of the rod pumping unit. The pumping control unit is configured to store (702) a first set of stroke timing data based on a first pressure level and a second set of stroke timing data based on a second pressure level, store (802) a set of pressure weights, and receive (804) a current pressure level. The current pressure level is between the first pressure level and the second pressure level. The pumping control unit is also configured to determine (806) a current set of stroke timing data based on the current pressure level, the first set of stroke timing, the second set of stroke timing, and the set of pressure weights, and initiate at least one stroke of the rod pumping unit.
Abstract:
Im Rahmen der Erfindung wurde ein Kompressor entwickelt. Dieser weist ein Kurbelgehäuse auf, in dem eine Kurbelwelle in einem Kurbelraum drehbar gelagert ist. Das Kurbelgehäuse enthält mindestens einen Zylinderraum, indem ein durch eine Pleuelstange exzentrisch an der Kurbelwelle gelagerter Kolben zu einer Hin- und Herbewebung anregbar ist. Die Kurbelwelle ist durch ein Zahnradgetriebe, dass einen Modulus m aufweist, mit einer Antriebsquelle verbunden, indem das an der Kurbelwelle angeordnete Zahnrad in das Zahnrad an der Antriebsquelle eingreift. Erfindungsgemäß ist die Drehachse der Kurbelwelle gegen die Mittelachse des Zylinderraums um einen Betrag dl versetzt, der ein ganzzahliges Vielfaches von m/2 ist. Unter der Mittelachse des Zylinderraums wird die vom Mittelpunkt der Grundfläche des Zylinderraums senkrecht zu dieser Grundfläche ausgehende Achse verstanden, entlang der der Kolben sich bewegt. Es wurde erkannt, dass auf diese Weise das Übersetzungsverhältnis des Getriebes in einen vorteilhaften Bereich geändert werden kann, ohne das an den Außenmaßen des Kompressors oder an der Antriebsquelle Veränderungen vorgenommen werden müssen. Insbesondere muss das Zahnrad der Antriebsquelle nicht geändert werden. Je nach Übersetzungsverhältnis kann das Betriebsgeräusch des Kompressors vermindert oder die Luftleistung erhöht werden.
