Abstract: Apparatus and methods for metering fluid to a fluid actuator. An example apparatus may include a hydraulic actuator, a fluid chamber, and a hydraulic directional control valve. The fluid chamber may include a piston slidably movable between first and second ends of the fluid chamber and dividing the chamber into first and second chamber portions. The hydraulic directional control valve may direct a fluid from a fluid source into the first chamber portion to cause a volume of fluid to be discharged out of the second chamber portion into the hydraulic actuator to actuate the hydraulic actuator by a distance corresponding to the volume of fluid received by the hydraulic actuator.

Abstract: Apparatus and methods for metering fluid to a fluid actuator. An example apparatus may include a hydraulic actuator and a fluid chamber. The fluid chamber may include a piston slidably movable between first and second ends of the fluid chamber and dividing the chamber into first and second chamber portions, a first port extending into the first chamber portion, and a second port extending into the second chamber portion. The apparatus may further include a hydraulic directional control valve operable to direct a fluid from a fluid source into one of the first and second ports to cause a volume of fluid to be discharged out of the other of the first and second ports into the hydraulic actuator to actuate the hydraulic actuator by a distance corresponding to the volume of fluid received by the hydraulic actuator.
