Abstract
A reversible power transmission for transmitting input power supplied from either direction. The transmission comprises in combination a plurality of fluid power units for driving or receiving power from a first plurality of fluid actuators. The first plurality of fluid actuators are timed together for cooperating in a mutually complementary manner to substantially linearize a normally pulsating power transfer. The first plurality of actuators may be connected to additional actuators for providing or receiving rotary motion or to plungers operating within stuffing boxes for constant flow pumping or fluid power transfer.
