Abstract
An electrohydraulic control unit for operating an actuator of a hydraulically controllable device is disclosed. The electrohydraulic control unit comprises a housing including a chamber for hydraulic fluid. The housing is coupled to the actuator such that a path for fluid communication between the chamber and the actuator is created. Disposed within the chamber is a piston for regulating the flow of the hydraulic fluid between the chamber and the actuator. An electric motor is securably attached to the housing. The electric motor includes a selectively rotatable shaft. The electrohydraulic control unit also comprises a converter configured to transform the rotational motion of the shaft to translational motion of the piston, thereby controlling the actuation of the hydraulically controllable device.
