Abstract

1471291 Antiskid braking systems TELDIX GmbH 11 Oct 1974 [13 Oct 1973] 44161/74 Heading F2F A vehicle antiskid brake system comprises a pressure source 8a, 8b a brake-line connecting the source to the vehicle wheel brakes, means in the form of a valve 9 for controlling the braking pressure, a valve arrangement for antiskid control, in the brake-line and operable in one position to allow passage of brake fluid from the brakes to a return line to reduce braking pressure and a valve for automatically closing the return line when the pressure of the source drops below a predetermined value. As shown the system has one circuit for braking the front wheels with antiskid control valves 10a, 10b, 11a, 11b and a second circuit for the rear wheels including valves 12a, 12b, valves 15, 16 being provided in respective return lines 13, 14 and having a closure member such as 15a urged on to the seat by a spring 15b having a force such that when the pressure of the source 8a drops to a predetermined value the valve closes. The valves 15, 16 may be replaced by solenoid operated valves each controlled by a pressure switch responsive to the pressure of reservoir 8a or 8b.
