Abstract

A simplified, quick exhaust assembly is provided for a proportional modulator for an electropneumatic braking system. A proportional valve has an enlarged diameter opening that permits direct communication between the delivery port and the exhaust port of the assembly. The opening is dimensioned to be substantially equal to the valve seat area provided by the piston and either meets or exceeds quick exhaust times over present arrangements.
