Title: Brake pressure proportioning device
IPC: B60T8/26
Filed: 1962-12-11
Abstract: 967,033. Fluid-pressure brakes. KELSEY-HAYES CO. Dec. 11, 1962 [Dec. 18, 1961], No. 46811/62. Heading F2F. A brake pressure proportioning device for use in a vehicle hydraulic braking system comprises a housing having inlet and outlet openings connected by a bore in which a piston, having a passage through it, is slidable, and a valve element responsive to deceleration of the vehicle is arranged to close the passage on the attainment of a predetermined vehicle deceleration to cause the pressure at the outlet to be subsequently modified in relation to that at the inlet. As shown, a brake pressure proportioning device is inserted in the conduit 16 between a master cylinder 18 and rear brake cylinders 24 and comprises a stepped piston 42 co-operating with small and large diameter portions 34, 36 of a stepped bore in a housing 10 having an inlet 12 and outlet 14. The bore is closed by a plug 38 drilled to provide a bore 76 in which is slidable a piston 78 urged by a spring 84 to a position in which an extension 90, extending through a by-pass passage 56 in the piston, prevents a ball 60, under the initial flow of fluid during commencement of a braking operation, from being washed up prematurely on to a valve seat 58. When pressure in the master cylinder increases, piston 78 moves to the right, allowing, when a predetermined deceleration force has been reached, movement of ball 60 up the conical face of valve seat 58 to block the passage 56. A transition period then occurs during which pressure continues to rise in the outlet but at a progressively slower rate, this being achieved by providing piston seals 52, 66 and a system of grooves in the piston connecting chamfered portions 50, 64 of the piston such that the seals distort into these chamfered portions causing increase of pressure at the shoulder 45 of the piston to move the piston to the right, until pressure at the inlet rises to a value beyond which the outlet pressure is reduced in a fixed relationship to the inlet pressure in a ratio determined by the effective diameters of the piston portions.
