    摘要： An apparatus for use in turning steerable vehicle wheels includes first and second pumps driven by a vehicle engine to supply fluid under pressure to a power steering motor assembly connected with the vehicle wheels. The first pump is sized to provide a fluid flow required by the power steering motor assembly to effect a first vehicle maneuver when the engine speed is at or above a first predetermined speed. A valve directs fluid flow from the second pump to the power steering motor assembly, which when combined with the fluid flow of the first pump is sufficient for the power steering assembly to effect a second vehicle maneuver when the engine speed is at or above the first predetermined speed. A greater fluid flow is required to effect the second vehicle maneuver than to effect the first vehicle maneuver.

    摘要： Disclosed is an arm stopper mechanism mounting apparatus including: an output shaft; a housing that is provided with a hole for inspecting the sealability of the interior thereof; a sealing member that seals the hole, and can be detached from the hole when the sealability is inspected; and an arm stopper mechanism that has a steering arm and a stopper. The steering arm includes an output shaft hole into which the output shaft is fitted; two tie rod holes to which the tie rods are respectively attached; and two striking surfaces which strike against the stopper. The stopper includes two contact surfaces. An angle made by the two contact surfaces of the stopper is greater than an angle made by the two striking surfaces of the steering arm, and is 90° or greater.
