摘要： A passage switching device to switch flow passages includes a rotary disk and a fixed disk which are stacked in an axial direction. The rotary disk is provided with at least one rotary disk communication path penetrating in the axial direction, and the fixed disk is provided with a plurality of fixed disk communication paths penetrating in the axial direction. The flow passages are switched by rotating and driving the rotary disk to switch combination of the rotary disk communication path and the fixed disk communication path for communication. There is provided an elastic member between the housing and the rotary disk, between the rotary disk and the fixed disk, and between the fixed disk and the housing with respect to the axial direction.

摘要： A valve device includes a housing integrally or separately having a flow path formation part where at least one flow path hole through which a fluid passes is formed. The valve device includes: a drive part that outputs a rotational force; and a rotation part that rotates about a predetermined axis by the rotational force output from the drive part. The rotation part includes a shaft and a rotor increasing or decreasing an opening degree of the flow path hole with rotation of the shaft. The rotor has a sliding surface that slides while facing an opening surface of the flow path formation part where the flow path hole is opened. At least a part of the rotation part is rotatably held by the housing.

摘要： A motor-driven axial-flow control valve is disclosed that has a valve body with an inlet and an opposite outlet and a passage located between having a substantially axial alignment relative to the inlet and outlet, and a flow control path arranged in the passage with an operative connection to a motor drive in a switch housing resting on the valve body. The flow control valve is formed by two radially arranged discs lying on one another and each having at least one passage opening where one disc is a stator disc permanently arranged in the valve body, and the other disc lies axially rotatably on the stator disk, and the rotatable disc is in engagement with an axially rotatable sleeve that is arranged axially in the passage and through which flow can pass in the cavity of the rotatable disc.

摘要： An adjustment device includes a body, an adjustment inner gear ring, and an adjustment shaft. The body has a cavity therein, has a first end provided with a first hole and a second hole, and has a peripheral wall provided with a third hole. The first hole, the second hole, and the third hole are connected with the cavity. The adjustment inner gear ring is fitted in the cavity, and has a peripheral wall provided with adjustment holes. The adjustment holes have different cross-sectional areas. A second end of the adjustment shaft has an adjustment gear and passes through the second hole into the cavity. The adjustment gear meshes with the adjustment inner gear ring. The adjustment shaft is rotatable to drive rotation of the adjustment inner gear ring so as to enable the third hole to be connected with the cavity through one of the adjustment holes.
