Abstract

1324595 Brake valves GIRLING Ltd 31 Dec 1970 [28 Feb 1970 18 March 1970] 9769/70 and 13116/70 Headings F2F and F2V A control valve for use in a vehicle antiskid braking system has a valve member 17 controlling communication between a port 16 connected to a pressure source, and a port 20 connected to an actuator controlling pressure to a wheel cylinder, member 17 being unseated by actuation of an armature 34 of a solenoid connected via a lost motion coupling to a push rod assembly engaging the member 17 to pass fluid pressure to the actuator to relieve the braking when the deceleration of the wheel exceeds a predetermined value. When the wheel reaccelerates to a given value the armature 34 is deenergized and moves rightwardly under the action of a spring 28 which engages a plate 27 connected via a nut 26 to an enlarged head 37 of a rod 25, the armature being arrested by abutment of a ring 39 with a flange 29 after member 17 engages seat 14 so that inertia of the armature is not transferred to the rod 25 but is taken by flange 29. Fluid returns to a reservoir via a port 6 and the rate at which the fluid returns can be controlled by replacing an orifice plate 44.
