ABSTRACT:
The spool of a fluid pressure control valve has an axial through-bore of a larger diameter at one end and a smaller diameter at the opposite end. A larger diameter pin is slidably received in the larger diameter end of the bore and a smaller diameter pin is slidably received in the smaller diameter end of the bore, and the pins are biased apart by a compression spring so as to be in abutment with the housing at both ends of the spool. Pressure from the outlet port is admitted into the through-bore of the spool between the pins so as to produce a feedback pressure force on the spool which is proportional to the value of the outlet pressure and the difference in area between the two pins.
