摘要： A hydraulic transaxle of the present invention includes an axle, a hydraulic static transmission (“HST”), a center case that has pair of oil passages for circulating the hydraulic oil between the hydraulic pump and the hydraulic motor, and a gear mechanism that transmits an output of the HST to the axle. A case supports the axle and accommodates the HST while also forming an oil reservoir. A hydraulic motor of the HST includes a motor shaft, a cylinder block with a plurality of cylinders fixed to the motor shaft, a plurality of pistons inserted into the cylinders, a fixed swash plate abutted by the plurality of pistons, and a fixed swash plate holder that supports the fixed swash plate with respect to the case. The motor shaft of the hydraulic motor is supported by the center case and the fixed swash plate holder.

摘要： Control systems and feedback assemblies for hydraulic axial displacement machines, such as pumps and motors. The control systems and feedback assemblies can reduce friction on the charging spools and provide for a more reliable return of the swashplate to a neutral position. Aspects of the control systems and feedback assemblies can be modularized for, e.g., easy maintenance and to reduce the overall size of the system.

摘要： A liquid air energy storage system comprises an air liquefier, a storage facility for storing the liquefied air, and a power recovery unit coupled to the storage facility. The air liquefier comprises an air input, an adsorption air purification unit for purifying the input air, and a cold box for liquefying the purified air. The power recovery unit comprises a pump for pressurising the liquefied air from the liquid air storage facility, an evaporator for transforming the high-pressure liquefied air into high-pressure gaseous air, an expansion turbine capable of being driven by the high-pressure gaseous air, a generator for generating electricity from the expansion turbine, and an exhaust for exhausting low-pressure gaseous air from the expansion turbine. The exhaust is coupled to the adsorption air purification unit such that at least a portion of the exhausted low-pressure gaseous air is usable to regenerate the adsorption air purification unit.

摘要： The invention relates to a compressed air energy storage system comprising a pressure accumulator (2) for gas to be stored under pressure, and a heat accumulator (27) for storing the compression heat that has accumulated during charging of the pressure accumulator (2), wherein the heat accumulator (27) is arranged ready for use in an overpressure zone (31). Said arrangement enables a structurally simple heat accumulator to be provided, since said heat accumulator is not loaded by the pressure of the gas passing therethrough.

摘要： Methods and associated systems for storing compressed air and extracting energy from the compressed air are disclosed. An exemplary method comprises: compressing air; storing the compressed air in a first storage tank at a first pressure; transferring the compressed air from the first storage tank to a second storage tank; storing the compressed air in the second storage tank at a second pressure lower than the first pressure; discharging the compressed air from the second storage tank; and extracting energy from the compressed air discharged from the second storage tank. The method may also comprise adding heat to the compressed air between the first storage tank and the second storage tank.
