Abstract: 1402150 Differential braking; proportioning valves; fluid pressure control valves; seals NISSAN MOTOR CO Ltd and SUMITOMO ELECTRIC INDUSTRIES Ltd 10 July 1972 [30 Aug 1971] 32178/72 Headings F2F F2V and F2B A dual hydraulic brake system includes a tandem master cylinder with front and rear sections 10a, 10b to supply pressure to front brake cylinders 26, 26<SP>1</SP> and to rear brake cylinders 18, 18<SP>1</SP> respectively; the pressure transmitted to the rear cylinders 18, 18<SP>1</SP> is modulated when this pressure reaches a predetermined value by means of a brake pressure proportioning valve 28 but in the event of failure of the supply to the front brake cylinders 26, 26<SP>1</SP> the modulating function of the valve 28 is stopped and the valve 28 acts as a mere passageway. The section 10a is connected to an inlet port 34 of the valve 28 and outlet ports 36, 38 connect with the front brake cylinders 26, 26<SP>1</SP>; the section 10b is connected to an inlet port 30 and an outlet port 32 connects with the rear brake cylinders 18, 18<SP>1</SP>. The valve 28 incorporates a differential piston 88 having valve head 102 cooperable with a valve member 106 to modulate the pressure at the outlet port 32; in response to pressure variations. The valve member 106 as seen in Fig. 3 has an annular valve seat 142 cooperable with the valve head 102 upon downward movement of the piston 88 against a compression spring 120: the valve member 106 also has a lip portion 130 engaging the wall of a bore 66 in the valve body 140 to prevent flow from port 30 to port 32 around the lip portion 130 but the lip portion 130 can be distorted radially inwardly to allow fluid flow from port 32 to port 30: the valve member 106 also has projections 134 abutting against a flange 112 on the differential piston 88 and with spaces 134 therebetween to permit fluid flow from port 30 to port 32 when the valve 102, 106 is not closed. The differential piston 88 has a lower stem portion 90 and an upper stem portion 98 slidable in respective bores 86, 200 in end closure members 70, 160 of the valve 28. The bore 200 communicates with the inlet port 34 and fluid pressure thereat acts on the stem portion 98 of the piston 88: loss of pressure at port 34 will allow spring 120 to move the differential piston 88 upwardly and stop the modulating function of valve 102, 106. The upper stem portion 98 is sealed by a Y-shaped seal member 100 which includes an 0-ring portion 212 and upper and lower sealing flanges 214, 216 having lip portions 214a, 216a engaging the stem portion 98. A thrust washer 206 having low frictional resistance engages the O-ring portion 212 and prevents twisting thereof when the closure member 160 is screwed into the valve housing 40. In the embodiment of Fig. 7 a back-up ring 208 slidable on stem portion 98 acts to prevent damage to lip portion 214a, although in the embodiment of Fig. 8 (not shown) this back-up ring is omitted.
