Abstract

The pressure equaliser is for use on dual circuit braking systems on agricultural vehicles. Fluid pressure from two circuits enters the inlet chambers (18,118) and acts on stepped pistons (26,126) which are displaced until the balls (52,152) strike the rods (62,162) of the centre shuttle allowing the fluid to pass into the outlet system (24) sending a balanced pressure to the vehicle wheels. For directional braking only one chamber (118) is pressurised. One piston (126) moves until the shuttle rod (162) strikes the ball (152) of the non return valve, but the pressure is insufficient to open the valve.
