Abstract

Improved accuracy and response of an EEGR valve (60) are obtained by novel constructional features of an upper stator member (194), a lower stator member (174), a bearing guide member (140), and a shell (64), and various inter-relationships between them for improved concentricity of parts, stable and accurate positioning of parts relative to each other, and better resistance to muddy water intrusion at an ambient air space (76) that provides for ambient air to pass through for cooling the valve. A lower stator member (174) has a through-hole (184) to which a bearing member (140) that guides a pintle shaft (114) is concentrically disposed. A frusto-conical surface (182) extends from through-hole (184) to the ambient air space (76).
