ABSTRACT:
A brake proportioning valve displaying low restriction to fluid flow and short fluid shear path is suitable for use in vehicular traction control systems and capable of supplying a high volume of fluid to the traction control system high pressure pump under atmospheric pressure. The proportioning valve employs a plunger of two diameters against which hydraulic pressure operates, and a plunger-located check ball held off its seat under low outlet pressure conditions by a control member. The brake proportioning valve provides proportioning of brake fluid pressure to the vehicle non-proportioned brakes relative to the vehicle proportioned brakes during both brake apply and brake release.
