20110214562 | CYLINDER DRIVING APPARATUS USING AIR PRESSURE - It is an aim of the present invention to overcome urgent and pressing global troubles directly associated with the human right to live, such as the energy crisis, the economic crisis, and environmental pollution and the like which cannot be delayed or neglected any longer in order to meet the needs of the times. Further, it is an aim of the present invention to significantly reduce the dependency on a variety of fossil directly associated with global warming. Therefore, the present invention provides a cylinder driving apparatus using air pressure, with maximized energy, characterized in that the use of fossil fuel energy is reduced and the use of clean energy is proposed. The present invention relates to a cylinder diving apparatus in which a plurality of flexible tubes connected to a crankshaft are filled with high pressure air, alternately expand by expansion energy, and are elevated to operate and rotate the crankshaft. Further, the preset invention relates to an apparatus for minimizing friction and eliminating gravitational force which may interfere with the elevating movement, to thereby maximize the efficiency of the conversion of compressed air expansion energy into rotating movement. The present invention achieves a great and active supplement and improvement over Korean Patent Registration No. 0041791 and No. 0210368 granted to the applicant of the present invention, ad proposes an inventive structure of an assistant tube that provides a novel energy source. Conventional apparatus use a variety of fossil fuels as a power source, whereas the present invention eliminates the repeated rise of oil prices ad ends energy problems, enables people to enjoy a stable life and aids in economic development, and provides all mankind with a new environmentally-friendly energy resource to take the place of the innumerable conventional power sources. The cylinder driving apparatus using air pressure according to the present invention comprises: a plurality of flexible tubes arranged in a case to flexibly move via high-pressure air; a connecting rod fixed at each f the flexible tubes, and which penetrates through an upper portion of the case; a crank shaft sequentially coupled to the connecting rod to rotate via the elevating movement of the connecting rod; a high pressure tank for supplying high pressure air to the flexible tubes via an air line; and a valve arranged in each of the flexible tubes to divide the space in the flexible tube into an upper section and a lower section and to open/shut airflow in the upper and lower sections. The valve is shut to block the upper and lower sections from each other when the flexible tubes are filled with high pressure air, and opens when the flexible tubes are elevated to top center. The valve is connected to an assistant tube, the interior of which is equipped with a tensile spring force to keep the assistant tube compressed, to enable compressed air in the flexible tubes to flow to the assistant tube when the valve opens. | 09-08-2011 |
20120118137 | COMPRESSED AIR ENERGY STORAGE SYSTEM UTILIZING TWO-PHASE FLOW TO FACILITATE HEAT EXCHANGE - A compressed-air energy storage system according to embodiments of the present invention comprises a reversible mechanism to compress and expand air, one or more compressed air storage tanks, a control system, one or more heat exchangers, and, in certain embodiments of the invention, a motor-generator. The reversible air compressor-expander uses mechanical power to compress air (when it is acting as a compressor) and converts the energy stored in compressed air to mechanical power (when it is acting as an expander). In certain embodiments, the compressor-expander comprises one or more stages, each stage consisting of pressure vessel (the “pressure cell”) partially filled with water or other liquid. In some embodiments, the pressure vessel communicates with one or more cylinder devices to exchange air and liquid with the cylinder chamber(s) thereof. Suitable valving allows air to enter and leave the pressure cell and cylinder device, if present, under electronic control. | 05-17-2012 |
20130019743 | PNEUMATIC ACTUATOR - A pneumatic actuator is provided for an active hood and includes a cylinder and a piston, which is movable in the cylinder between a lower terminal position, in which the volume of a chamber delimited by piston and cylinder, which may be impinged using compressed gas, is minimal, and an upper terminal position, in which the volume of the chamber is maximal. The piston is lockable in the lower terminal position by a detent body engaging in first recesses of the cylinder and the piston. A slider is displaceable by impingement using the compressed gas out of an idle position, in which it fixes the detent body in the first recesses, into a triggering position, in which a second recess of the slider overlaps with one of the first recesses and is capable, together with a single one of the first recesses of accommodating the detent body. | 01-24-2013 |
20140026746 | VOLUME BOOSTER WITH STABILIZED TRIM - A fluid flow control device includes a body having an inlet connection, an outlet connection, and a discharge port. A supply path extends between the inlet connection and the outlet connection and a booster module is disposed within the body. The booster module includes a control element and an actuator element and defines an exhaust path extending between the outlet connection and the discharge port. A supply port is disposed within the booster module along the supply path between the inlet connection and the outlet connection and at least a first damping means operatively connected to the booster module. | 01-30-2014 |
20140174286 | TELESCOPIC POSITION ADJUSTMENT MECHANISM - A telescopic position adjustment mechanism allows for a telescoping element to be indexed by fixed increments toward a more telescopically collapsed position, relative to its base. The telescopic position adjustment mechanism uses a stepping reservoir that can, in a stepping configuration, selectively receive a predetermined volume of fluid from a support reservoir that supports the telescoping element against the base, enabling the telescoping element to collapse toward the base by a distance corresponding to the predetermined volume of fluid. In a locking configuration, the volume of fluid in the support reservoir is constant and the telescopic position is fixed, and in a free movement configuration fluid can flow freely between the support reservoir and a sink reservoir to permit free telescopic movement. A rotation resistance mechanism uses a locking key that is biased into engagement with a locking channel to inhibit rotation of the telescoping element relative to the base. | 06-26-2014 |
20160039079 | HYDRAULIC HAMMER HAVING SINGLE PIECE SEAL ASSEMBLY - A seal assembly for a hydraulic hammer is disclosed. The seal assembly may include a seal carrier having at least one annular recess. The seal assembly may also include at least one seal integrally molded onto surfaces of the at least one annular recess. | 02-11-2016 |
20160061232 | Energy Efficient Fluid Powered Linear Actuator With Variable Area - Hydraulic actuation systems having variable displacements and energy recovery capabilities include cylinders with pistons disposed inside of barrels. When operating in energy consuming modes, high speed valves pressurize extension chambers or retraction chambers to provide enough force to meet or counteract an opposite load force. When operating in energy recovery modes, high speed valves return a working fluid from extension chambers or retraction chambers, which are pressurized by a load, to an accumulator for later use. | 03-03-2016 |
