Auxiliary power steering system with relief valve control |
摘要 |
The maximum operating pressure for the fluid servomotor of a fluid power operated steering system is varied as a function of steering displacement by varying the spring prestress bias on a relief valve controlling fluid discharge from the operating chamber of the fluid servomotor. The valve spring prestress is controlled by a spring engaged plunger that is displaced relative to the servomotor piston during steering displacement.
