  • Patent number: 4240327
    Abstract: A fluid operated linear actuator control system for drive arrangements of the type wherein two fluid operated linear actuators act upon a shaft at an angle with respect to each other for causing rotation thereof is disclosed. The control system includes a fluid pressure source including a reservoir means, fluid passages connecting the pressure source with each of the fluid operated linear actuators, and control means for communicating the first of the linear actuators with fluid from the pressure source and fluid from the other with the reservoir means to displace the drive arrangement through a first arc sector, and for changing-over the communication to communicate the reservoir with fluid from the one actuator and the other actuator with fluid from the pressure source causing displacement of the drive arrangement through a second arc sector, wherein one of the actuators is in a driving mode while the other actuator is in a floating mode.
