Abstract
Improvements in pressure differential warning actuators in hydraulic brake systems for vehicles, characterized in that the assembly comprises a piston that works in a bore in the box, and a pair of axially separated flexible diaphragms that act on opposite ends of the piston and they are intended to be exposed on their faces opposite the piston to pressures in the brake circuits, the effective areas of the diaphragms being greater than that of the piston, but, normally, when the assembly is in the central inactive position and the differential pressure is below of the predetermined value, the regions of the diaphragms radially out of the pistons are in contact with the walls of the box at opposite ends in anima so that the effective areas of the ends of the assembly are equal to those of the piston, the device having the characteristics necessary so that when the differential pressure exceeds the default value After the piston has been moved relative to the bore by means of one of the diaphragms and activates the indicating device, the diaphragm penetrates into the bore at the end and the other diaphragm is forced to separate from the wall at the opposite end of the bore by what is exposed to the pressure over its entire effective area, and when the pressure differential is reduced to a value less than the predetermined value, the force applied to the assembly by the pressure acting on the entire effective area of the other diaphragm, restores the Set to center idle position and indicating device is deactivated.
