Abstract
This double acting check valve allows hydraulic power steering oil to flow from the power steering pump through the valve to the power steering gear in normal operation. During an impact load at the tire, the piston in the gear forces the oil from the gear to the check valve which controls or meters the oil flow and pressure so that the impact is not transmitted back to the steering wheel. In the event that the impact load is severe and pressures build up within the power steering gear, as a result, the blow off valve opens to allow such back flow to reduce or eliminate damage to the gear housing.
