Abstract
A drain valve for a compressed air brake system of a vehicle comprises a valve housing defining a valve chamber open at one end and a drain aperture at the opposite end. A poppet has a poppet body at least partially received in the valve chamber and provided with a seal. The poppet is slidable between a closed position in which the poppet and the seal contact the inner wall of the valve housing around the drain aperture thereby closing the drain aperture, and an open position moved away from the drain aperture. A spring urges the poppet to the closed position. The poppet and the seal are incorporated in a single multi-component injection molded plastic part comprising at least two components. The poppet body is formed of a first plastic component and the seal is formed of a second plastic component partially embedded in the first plastic component.
