摘要： A hybrid hydraulic drivetrain is configured to propel a vehicle and regenerate propulsion energy. The drivetrain includes a prime mover, an accumulator, an axle, a first rotating group, a second rotating group, and a hydraulic transformer. The first rotating group is configured to receive shaft energy from the prime mover, receive shaft energy from the drive axle, send shaft energy to the drive axle, receive hydraulic energy from the hydraulic accumulator, and send hydraulic energy to the accumulator. The second rotating group is configured to receive shaft energy from the prime mover. The hydraulic transformer is configured to charge the accumulator with hydraulic energy received from the second rotating group. The hydraulic transformer may be remotely mounted from the second rotating group. The second rotating group may supply hydraulic energy to an auxiliary circuit of the vehicle. The auxiliary circuit may operate with the prime mover shut down.

摘要： Example fluid circuits (e.g., within aircrafts) include first and second pump assemblies. The first pump assembly has an electric motor and a first fluid pump. The first fluid pump is coupled to the electric motor and has a case drain port that is in fluid communication with a case drain region of the first fluid pump. The second pump assembly is powered by hydraulic pressure from the first fluid outlet of the first fluid pump and functions to augment flow through the case drain region of the first fluid pump.

摘要： Method of conversion of heat into fluid power includes pumping of the working liquid into a hydropneumatic accumulator with gas compression, subsequent gas expansion with displacement of the working liquid from the other accumulator as well as supply of heat to the gas by transferring the gas through the hotter heat exchanger and removal of heat from the gas by transferring the gas through another, colder heat exchanger performed so that the average temperature of the gas during expansion is higher than that during compression, wherein the gas is transferred between different accumulators through said heat exchangers.
The device for conversion of heat into fluid power includes at least two accumulators, the means for liquid supply and intake as well as the means for heating and cooling containing at least two flow-type gas heat exchangers installed with the possibility of gas transfer through them between gas reservoirs of different accumulators.
The efficiency and rate of heat conversion into fluid power are increased. Reliability and high power density are ensured.
