This power steering gear has steering travel limiter for controlling the input rotation so that the hydraulic valve of the gear cannot be moved to a closed position previously established by contact of the wheel stop or internal stop in the gear. The limiter in the preferred embodiment employs a series of rings which are engaged in series in response to handwheel input and which prevent rotation of the input beyond a certain point at or inboard of internal stops or the wheel stops so that the valving of the gear cannot close to a point requiring the power steering pump to operate in relief.
