ACTUATORS
Document Type and Number:
WIPO Patent Application WO2008100830
Kind Code:
A9
Abstract:
Actuators suited for use with, for example, vehicular suspension systems. In some embodiments, the present actuators include a reversible hydraulic pump configured to produce variable hydraulic pressure; a hydraulic cylinder assembly (60) having a cylinder bore, and a piston (80) positioned within the cylinder bore (70) that is axially movable relative to the cylinder bore; an a hydraulic circuit hydraulically coupling the reversible hydraulic pump (30) to the hydraulic cylinder assembly. In these embodiments, actuated axial motion of the piston relative to the cylinder bore is accomplished without the use of check valves, pressure regulating valves, or actively controlled valves.
