ABSTRACT:
A hydraulic fluid driving arrangement for land, water or air vehicles includes rotary hydraulic motors driving respective propellers. The motors are arranged in pairs, with the two motors of each pair being on respective opposite sides of the longitudinal axis of the vehicle. One or more hydraulic pump is driven by a prime mover and deliver hydraulic fluid under pressure to two or more separate outlets, with the flows in all outlets being either proportionate or equal to each other, and the outlets being completely separate from each other. One outlet supplies fluid to the motors on one side of the vehicle's medial plane of symmetry and the other supplies fluid to the motors on the other side of the vehicle's medial plane. Respective flow adjustment means may operably associated with each outlet, and may be operated either independently or conjointly. Alternatively, control of the motor speeds may be provided by bypasses. Two or more outputs of the hydraulic pumps may be combined to supply two or more motor supply lines with equal or proportionate flows, with check valves being provided to prevent reverse flow.
