Abstract: A pressure-compensating valve for use with a hydraulic skid control brake system wherein a cylindrical bar stock piece is machined to provide a center flow pintle cooperable with an annular scanning annulus, thereby to provide a stepped and partially infinitely variable valve which permits partial or full diameter area sections to freely be sensed in a balanced state relieving any tendency for the pressure-compensating valve to bind or otherwise develop hydraulic imbalance.

Abstract: Two confronting relatively movable radial surfaces formed by a stationary pressure part and a movable valve part respectively, have an axially projecting circumferentially continuous shoulder formed on one of the parts and disposed between the surfaces to partition the space between the two parts into an inlet zone and an outlet zone. The valve part is moved axially as a function of fluid flow to by-pass fluid directly across the shoulder into the inlet zone from the outlet zone.
