  • Synchronizer for hydraulic actuators
    Patent number: 4241581
    Abstract: A synchronizer is provided for synchronizing the movements of two hydraulic actuators. The synchronizer consists of a two-piston pump which supplies hydraulic fluid to both actuators. The two pistons are mechanically connected so as to move simultaneously through equal distances, and on each complete stroke of the pump, each actuator receives fluid from both cylinders of the pump, so that both actuators receive precisely equal amounts of fluid.
