ABSTRACT:
A reversible proportioning valve allows pressure to the rear brake cylinder of a vehicle to follow pressure to the front brake cylinder in a ratioed relationship, when pressure to the front brake cylinder is decreasing. The reversible proportioning valve of the present invention accomplishes this by enabling ratioed pressure between the front and the rear brakes for both increasing and decreasing pressures, resulting in driver controlled modulation of pressure. The reversible proportioning valve uses a stepped piston/cylinder to control pressure without the use of external power.
