Abstract
An EGR device includes a housing and a valve. The housing has an outer pipe and an inner structure. The inner structure is located inside the outer pipe to define an annular passage externally with the outer pipe. The inner structure defines an inner passage internally. The inner structure has apertures. The valve is in a tubular shape and is located inside the inner structure. The valve is slidable in an axial direction to communicate the annular passage with the inner passage through the apertures and to block the inner passage from the annular passage.
