Beschreibung
Zusammenfassung:	Embodiments of the invention provide an electro-hydraulic actuator including an electric linear actuator, a double chamber hydraulic cylinder, and a hydraulic actuator. The double chamber hydraulic cylinder includes a double chamber piston coupled to the electric linear actuator and defining a first double chamber volume and a second double chamber volume. The hydraulic actuator includes a hydraulic actuator housing, a first rack piston, a second rack piston, a rack arranged between the first rack piston and the second rack piston, and a pinion engaged with the rack. A first hydraulic actuator volume is defined between the hydraulic actuator housing and the first rack piston in communication with the first double chamber volume, and a second hydraulic actuator volume is defined between the hydraulic actuator housing and the second rack piston in communication with the second double chamber volume.
