Abstract

1337911 Hydraulic brakes BENDIX CORP 14 Feb 1972 [8 March 1971] 6846/72 Heading F2F A brake pressure-proportioning valve has an inlet 16, and an outlet 22 connected thereto by a bore 14 containing a valve device dividing the bore into inlet and outlet chambers 28, 30 and which permits substantially uninhibited fluid communication between the chambers until a first predetermined fluid pressure in the inlet chamber is attained, whereupon the valve device restricts flow to allow the inlet pressure to increase more rapidly than the outlet pressure until a second predetermined pressure is attained, the fluid pressure in the outlet chamber then being allowed to increase more rapidly than the inlet pressure until equal therewith whereupon the valve device once more permits uninhibited flow of fluid. The valve device includes a piston 32 having a smaller end 34 and larger end 36 and a valve member 58 which engages the piston, when it is moved under fluid pressure against a spring 52, to close a passage 56. As the fluid pressure in chamber 28 increases a sleeve 40 and piston 32 moves as a unit and the valve opens again. (For Figure see next page.)
