    Abstract: A check valve is made of a resilient body wound in a ring form and is located in an annular flow passage. A displacement limiter includes: a limiter main body that is located on an outer side of the check valve and is configured to limit displacement of the check valve in a diameter increasing direction of the check valve; and a limiter flow passage that communicates between one side and the other side of the limiter main body in an axial direction to enable hydraulic oil to flow between the one side and the other side of the limiter main body through the limiter flow passage.

    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.

    Abstract: A valve device includes a housing, a stationary disk, a drive device, a shaft and a rotor. The stationary disk is fixed at an inside of the housing and has at least one flow passage hole. The shaft is rotated about a central axis by the drive device. The rotor increases or decreases an opening degree of the at least one flow passage hole. The rotor includes: a drive disk that slides relative to the stationary disk; and a lever that is fixed to the drive disk and couples between the drive disk and the shaft. A torsion spring is placed between the shaft and the lever and urges the lever relative to the shaft in a circumferential direction around the central axis of the shaft. The shaft has a plurality of contact portions configured to contact the lever and respectively located at a plurality of locations.

    Abstract: A valve device includes a flow path formation member provided with at least one flow path hole through which a fluid passes, and a drive part that outputs a rotational force. The valve device includes a shaft, and a rotor having a sliding surface that slides while facing an opening surface of the flow path formation member where the flow path hole is opened, and the rotor is configured to increase or decrease an opening degree of the flow path hole with rotation of the shaft. The valve device includes an energization member that energizes the rotor toward the flow path formation member. The valve device includes a coupling structure configured to tiltably couple the shaft to the rotor such that a contact state between the sliding surface and the opening surface is held regardless of a posture or a position of the shaft.
