Abstract
A dump valve for selectively placing the inlet port of a height control valve into communication with a source of pressurized air or atmosphere. The dump valve comprises a body having a control bore, an opposing pilot bore, an exhaust bore intersecting the control bore, and a connection bore intersecting the control bore. The connecting bore has means for fluidly connecting the connection bore to the inlet bore of a height control valve. A valve seal disposed within the control bore for reciprocal movement therein selectively places the connection port in communication with either the supply port or the exhaust port. A piston axially disposed in the pilot bore for reciprocal movement therein controls the movement of the valve seal in response to the selective application of pressure to the pilot bore.
