ABSTRACT:
A hydraulically driving and controlling - unit comprises a power plant which drives a fluid flow producing device for the separate production and supply of pairs of flows of hydraulic fluid under pressure. The unit supplies at least one pair of flows to at least two fluid motors. Rates of flow in flows are proportionate to each other whereby motors of same pair of flow are actuated and maintained to act with to each other proportionate speed of motion. Unit may be transportable and adaptable to machines or vehicles. The drive unit may include a plurality of power plants and fluid flow producing devices. In such multiple unit one way valves are set into fluid lines which may combine partially after those one way valves for directing each one flow from a different power plant to the same motor. Thereby the unit can continue to operate, when one of the plurality of power plants fails. The proportionateness of speed of motion of the motors which is enforced by the proportionateness of rates of flow in the separated flows can be utilized to equalize or synchronize the motion of machines or vehicles or of driving members thereof.
