Document Type and Number:
Japanese Patent JP6672985
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress an increase in consumption of washing liquid in a washer tank.SOLUTION: In an on-vehicle optical sensor washing device 10, a constant capacity pump 80 is provided between a washer pump 14 and an injection port of an optical sensor washing nozzle 150, and by actuation of the constant capacity pump 80, a constant capacity of washing liquid is supplied to the injection port of the optical sensor washing nozzle 150. Therefore, even when voltage dispersion at the time of the actuation of the washer pump 14 occurs, or even when dispersion in temperature, density, and viscosity of the washing liquid due to variation of use environmental temperature occurs, the constant capacity of the washing liquid can be supplied to the injection port of the optical sensor washing nozzle 150 by the constant capacity pump 80. Therefore, an increase in consumption of the washing liquid in the washer tank 12 can be suppressed.SELECTED DRAWING: Figure 1
