DOUBLE-ACTION HYDRAULIC PRESSURE REGULATOR OF VEHICLE BRAKE SYSTEM Russian patent published in 1994 - IPC

FIELD: vehicle brake systems. SUBSTANCE: casing 1 accommodates two sections with pistons of pressure regulators of left and right braking mechanisms, and two hydraulic sections with pistons. Each such section is hydraulically communicated with right and left suspension posts. Each of the four sections is received in separate hole of the casing and enclosed by a jacket. The casing has two lugs with holes to receive shaft 15 extending through flanges positioned in line with the longitudinal axis of lever 14. One end of lever 14 in front of each pair of pistons carries two equalizers 12 and 4 having axes 13 and 5 of oscillation. Axis 5 extends midway between pistons of the sections. The other end of the lever carries adjustment stop including threaded rod 18 and spherical nut 19 located in a plane passing through the axes of the equalizers and connected to adjustment spring 17 secured to support 16 affixed to the casing.
