摘要： 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.

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 ceramic valve with a function of informing the operation position includes casing, a drive device partially and rotatably secured in the casing, a clicker longitudinally mounted to an upper portion of the casing and an outlet control device mounted to a lower portion of the casing for holding the drive device in place, wherein the drive seat extending through the clicker. The clicker informs an operation position by a “click” sound when the outlet control device is driven to a cold water supplying position, a hot water supplying position and a mixing water supplying position.

摘要： A switching valve is constructed such that a rotor is rotatably provided inside a body and a cover member is provided with respect to the body so as to face a table part of the rotor. A gap having a prescribed interval is provided between an upper surface of the table part and the cover member, and a valve body biased toward the cover member side is provided to the table part. When rotating, the rotor does not slide on the bottom surface of the cover member, and leakage of a liquid from an inlet port is prevented due to the valve body seated on and closing an outlet port that is not the outlet port which is provided to the cover member so as to cause the liquid to be outputted therethrough.

摘要： A faucet assembly includes a non-metallic valve body, a valve, a handle adapter, and a retaining clip. The non-metallic valve body includes a longitudinal opening disposed therein and a slot disposed within a side portion thereof. The valve is at least partially disposed within the longitudinal opening. The valve includes a body and a stem extending upwardly from the body, and the stem is configured to rotate relative to the body. The handle adapter is removably coupled to the stem and is rotatably coupled to the non-metallic valve body. The retaining clip is removably inserted into the slot of the non-metallic valve body to limit longitudinal movement of the valve within the non-metallic valve body.
