Abstract
A valve device increases or decreases a flow rate of EGR gas. The valve device includes a housing, a bypass valve body, an EGR valve body. The housing includes: a first upstream passage into which the EGR gas cooled by an EGR cooler flows; a second upstream passage into which the EGR gas that bypasses the EGR cooler flows; a junction connected to each of a gas-flow downstream of the first upstream passage and a gas-flow downstream of the second upstream passage; and a downstream passage connected to the first upstream passage and the second upstream passage via the junction. The bypass valve body is provided in the second upstream passage. The EGR valve body is provided in the downstream passage.
