Abstract

In a bidirectional power transmission system including a bidirectional, hydraulically engaged clutch (18) adapted to be coupled to a source of rotary power (10) and to a rotary drive (14) and having two hydraulic inlets (30, 32) each for receiving hydraulic fluid under pressure, one (30) to engage the clutch to cause one direction of rotation of the drive and the other (32) to engage the clutch to cause the opposite rotation of the drive, a source (34) of hydraulic fluid under pressure, a direction control valve (40) interconnecting the source and one or the other of the inlets, a hydraulic pressure modulating device (36) connected between the source and the valve, the improvement including an accumulator (46) connected to each of the inlets between the clutch and the valve for receiving hydraulic fluid under pressure when the valve is directing fluid to the associated inlet.
