Abstract
An anti-skid brake control system comprises a cylinder casing having a first chamber connected with a master cylinder and a second chamber in communication with wheel brake cylinders, a cut-off valve disposed within the first chamber for selectively interrupting fluid communication between the first and second chambers, and a hydraulic capacity controller including a plunger axially reciprocable within the first chamber and operatively engaged at its both ends with the cut-off valve and a piston reciprocable within a vacuum servo-motor, the plunger being retracted by the piston to activate the cut-off valve and thereafter to increase the capacity of the second chamber to decrease the braking pressure applied to the wheel brake cylinders. The control system further comprises a relief valve interposed between the second chamber of the casing and a reservoir of the master cylinder to be opened when the capacity of the second chamber is maximized by retraction of the plunger, and an orifice interposed between the relief valve and the reservoir for controlling fluid flow from the second chamber to the reservoir.
