Brayton cycle engine

Air hybrid vehicle

Fluid-pressure-actuated motor

The crankcase 67 of an internal combustion engine 8 generates alternating high and low pressure which is fed through distributor 151 to the high pressure chamber 125 and low pressure chamber 123 of motor 13. Non-return valve 171 allows fluid under pressure to enter chamber 125 but not to leave it and valve 169 permits the evacuation of chamber 123 but not its pressurization. This results in a pressure difference across piston 127, under which it moves against the bias of spring 141 until valve 193 opens to remove the differential, when spring 141 drives the piston back to the point where studs 221 shut valve 193 and so cause the cycle to repeat. The stroke of piston 127 is governed by the pressure difference across it and hence by the amplitude of the crankcase pressure. Valve spring 201 is sufficiently compressed after a short stroke to overcome the pressure across 193 when this is low, but a high pressure will drive the piston to the point where post 302 opens the valve. The motor is ...

Dual turbine direct drive pump

A pump system and method of operating the same may utilize two relatively smaller turbines that are attached to and used to power a single pump. The two turbines are releasably coupled to the pump via respective one-way clutches, thereby enabling the use of one or both turbines at a time to power the pump. At low loads (e.g., low pump outputs), only one turbine operates to power the pump, and at higher loads (e.g., high pump outputs), both turbines operate to power the pump. By using two smaller turbines instead of one large turbine, the range-ability of the turbine power at the most efficient operating ranges is increased. This improves the fuel efficiency of the pump system.
