  • Publication number: 20230243432
    Abstract: A valve device includes a housing, a stationary valve and a drive valve. The stationary valve is placed in a fluid passage of the housing. The stationary valve forms a first passage, which conducts fluid, and a penetrating chamber which penetrates through the stationary valve in the axial direction. The drive valve is placed on one axial side of the stationary valve in the fluid passage and forms a second passage which conducts the fluid. The drive valve communicates the second passage to the first passage through rotation of the drive valve. The housing has a bottom portion that covers the penetrating chamber from another axial side. An upstream passage of the fluid passage, which is located on an upstream side of the drive valve and the stationary valve in a flow direction of the fluid, is communicated with the penetrating chamber through a communication passage.
