ABSTRACT:
A diaphragm valve has a relatively long seating formed by a plurality of ribs which engage with one air operated diaphragm. An annular valve is provided by slotting the outer surface of an annular seating member which engages an endless diaphragm, alternate slots communicating with the inlet or outlet of the valve. A pneumatic actuator for a vehicle braking system is provided with internal valve means for controlling the flow of air through the movable wall carrying the actuating member. An anti-skid braking system employs such a pneumatic brake actuator, the internal valve means being operated by skid sensing means.
