Abstract
A hydraulic power steering gear (10) comprises first and second relatively rotatable valve members (40 and 42). The first valve member (40) includes a radially extending passage (64). The second valve member (42) has an arcuate cam surface (184). A detent member (220) acts between the first and second valve members (40 and 42). The detent member (220) has a curved outer surface (252). A spring (240) biases the detent member (220) radially outward against the cam surface (184). The spring (240) is disposed in the radially extending passage (64) in the first valve member (40). The detent member (220) is disposed in the arcuate cam surface (184) in the neutral condition and provides a physically perceptible indication to a driver of the vehicle of operation of the steering gear (10) between the neutral condition and the actuated condition.
