ABSTRACT:
Dual function valve assemblies mounted within the operating piston of a power steering servomotor, control the flow of pressurized fluid between opposing piston chambers to both limit travel of the piston and limit the maximum pressure developed within the pressurized chamber by cutting off the pressure as the piston approaches a limit position and relieving excess pressure during piston travel.
