Subject inventions use a bunch of hydraulic cylinders with cross section area in a series of powers of 2 multiples of the least common denominator. By selection from N pieces of such cylinders with corresponding digital-controllable valves array, the enumerateable quantity of different areal sums shall read: Nth power of 2. With proper switching on the bunch of cylinders, adjustable fluid power supply can be realized to adapt very wide pressure fluctuation of input. Also a novel system of hydrostatic transmission & powertrain is presented, and it features automatic quasi CVT (Continuously Variable Transmission) & regenerative brake with reclaimed energy round trip via same tranny, by virtue of not expensively using planetary gears or variable displacement hydraulic pump/motor. All vehicles, even powered only by fossil fuel, deserve economic regenerative brake, now this invention can make it come true!
