<p>A selector valve for a vehicle braking system in which brakes mounted on opposite sides of the vehicle can be operated selectively either together or independently, comprises an operating lever (9) for displacing a valve spool (2) to control communication between inlet ports (3,4) and outlet ports (5,6), the lever being guided by a slot (8) which includes latching notches (20) in which the lever is engageable to preselect a particular steering mode of brake operation. The lever is automatically disengaged from the notches after each brake operation by a piston (15) which is actuated by the fluid pressure in a chamber (16) connected to an inlet port (4).</p> |
