Title:
VALVE DEVICE
Document Type and Number:
Japanese Patent JP2016151340
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a valve device 1 which can correct the displacement of a valve-opening start angle caused by the positional displacement of a valve opening part 4a.SOLUTION: In a valve device 1, a light permeation part 9a which allows the permeation of light is arranged at a part of a flow-out port 9, and an illuminance sensor 16 is mounted in a sensor cover 15. At valve-closing, since light which permeates the light permeation part 9a, and intrudes into the flow-out port 9 is blocked by a rotary valve 4, the light does not arrive at the illuminance sensor 16. On the other hand, at valve-opening, since the light which permeates the light permeation part 9a, and intrudes into the flow-out port 9 is not blocked by the rotary valve 4, the light arrives at the illumination sensor 16 through a light route. An ECU 14 stores a rotation angle of the rotary valve 4 when the illumination sensor 16 detects luminance at a constant level or higher as a valve-opening start angle into a memory, and corrects displacement with the valve-opening start angle on a layout on the basis of the storage information.SELECTED DRAWING: Figure 3
