Abstract
An electrohydraulic actuator has a housing divided into pump and cylinder portions respectively containing a centrifugal impeller driven through a hub by an externally mounted motor, and a pushrod actuated by a piston and arranged to advance the piston and pushrod to deliver thrust when the motor is operated. The major parts except the motor and the pushrod are castings and only one size castings are required for a large range of thrust capacities. The impeller casting is machined to a diameter suitable for a desired thrust and a motor of required speed and horsepower for that thrust capacity is selected to drive the impeller.
