摘要： A linear actuator for vehicle power steering systems with at least three steered wheels of a double-acting type that comprises a cylindrical body, closed at opposite ends; a piston, accommodated inside the cylindrical body axially slideable between the ends; and a stem, rigidly associated with the piston, coaxial to the cylindrical body, and protruding from at least one of the ends, the piston dividing the cylindrical body into two chambers, each provided with an inflow/outflow opening formed at the two opposite ends; and at least one pair of one-way valves, provided in the piston with a respective inlet connected to a respective chamber and outlets mutually connected, each valve having a stem slideably accommodated in the respective inlet with one end associated with a respective flow control element and the opposite end that protrudes externally from the piston, so as to open a respective valve.
