  • EGR device having rotary valve
    Patent number: 9771902
    Abstract: An EGR device includes a housing having an outer pipe and an inner pipe. The inner pipe is accommodated in the outer pipe to define an annular passage externally with the outer pipe. The inner pipe defines an inner passage internally. The inner pipe has pipe through holes. A rotary valve is accommodated in the inner pipe. The rotary valve has valve through holes. The rotary valve is rotatable to communicate the annular passage with the inner passage through the valve through holes and the pipe through holes. The rotary valve is rotatable to block the inner passage from the annular passage.

  • EGR device having slidable valve
    Patent number: 9541035
    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.
