ABSTRACT:
A hydraulic system for use in the propulsion of motor vehicles includes at least two volume multipliers each having a high pressure port, a low pressure port, and a piston in a chamber separating the high and low pressure ports. A prime mover and associated main hydraulic pump is arranged to alternately supply high pressure fluid to the high pressure ports of the multipliers, so as to produce a reciprocating motion in the pistons and create a continuous flow of high pressure fluid from a reservoir through the pump, into the high pressure port of one volume multiplier, out of the high pressure port of the other multiplier, and back to the reservoir. The reciprocating pistons are used to create a second, separate continuous flow of low pressure hydraulic fluid which circulates from the low pressure port of one volume multiplier through one or more hydraulic driving motors adapted to propel the vehicle, and back to the low pressure port of the remaining multiplier.
During deceleration of the vehicle, the prime mover may be turned off, whereupon the pistons no longer reciprocate. Low pressure fluid is directed through a path that includes the driving motors, now acting as pumps, and a brake motor mechanically coupled to a regenerative pump connected in the high pressure system. The latter is used to pump fluid from the reservoir into one or more accumulators disposed in the high pressure system, so as to store energy therein for later use.
