091462000 | For double-acting motor | 6 |
20100242719 | HYDRAULIC LOAD CONTROL VALVE DEVICE - A hydraulic load control valve ( | 09-30-2010 |
20120042772 | 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. | 02-23-2012 |
20140060316 | Vibration Energy Harvest Device - The present invention relates to a vibration energy harvest device. In the present invention, the vibration energy harvest device is provided for being used to recycle the mechanical energy and thermal energy generated during the vibration, and effectively to improve the power generation efficiency with newly added hydraulic motor and electricity generating unit. Wherein by using an ameliorating valve module and removing the damping hole in the prior art, no matter the damping oil flows from inner cylinder module through hydraulic motor to outer cylinder module or the contrary direction, the flowing damping oil could avoid the hydraulic motor from reciprocating to improve the power generation efficiency. | 03-06-2014 |
20150128795 | ROTATING MECHANISM - A rotating mechanism includes a holder assembly, a rotating assembly, and a valve assembly. The holder assembly includes a mounting block. The rotating assembly includes a shaft and a rotating block. The shaft is mounted to the holder assembly. The rotating block is sleeved on the shaft and is mounted to the mounting block. The valve assembly communicates with the mounting block so that gas is capable of coming in to the mounting block to drive the rotating block to rotate and make the shaft rotate. | 05-14-2015 |
091463000 | With means to provide unequal flow rates to or from opposed working chambers | 1 |
20150354604 | Hydraulic Adjusting Device - A hydraulic adjusting device, in particular for use in a power plant and/or a wind power plant, includes a double-acting adjusting cylinder that has an adjusting function for a working operation and for a special operation. The double-acting adjusting cylinder is configured to be pressurized with a working pressure medium. In order to satisfy the adjusting function in the special operation, the double-acting adjusting cylinder is further configured to be connected to a pressure medium reservoir that has a pressurized gas isolated from the working pressure medium. The adjusting cylinder has a working chamber configured for the adjusting function of the special operation, the piston area of which is coupled to a piston arrangement of the adjusting cylinder that is configured for the working operation or is configured to be coupled to the piston arrangement. | 12-10-2015 |
091466000 | Unitary inlet and exhaust valve means for opposed working chambers | 1 |
20140102289 | SHOVEL AND METHOD FOR CONTROLLING SHOVEL - A shovel according to an embodiment of the present invention is a shovel including a boom cylinder and an arm cylinder. The shovel includes a hydraulic motor driven by hydraulic oil flowing out of the boom cylinder, a regenerating oil passage configured to supply the hydraulic oil flowing out of the boom cylinder to the hydraulic motor, a reusing oil passage configured to supply the hydraulic oil flowing out of the boom cylinder to the arm cylinder, and a reusing flow control valve configured to control a flow rate of hydraulic oil flowing in the reusing oil passage. | 04-17-2014 |
