ABSTRACT:
Pressurized fluid from an engine driven pump is supplied to and exhausted from the opposed chambers of a hydrostatic power steering servomotor through control passages in a valve housing and in a rotatable valve body coupled through viscous liquid to a steering control shaft. A pressure signal from the pressurized chamber of the servomotor is supplied by the control passages to a valve between the pump and fluid reservoir to limit operating pressure as a function of servomotor loading.
