Document Type and Number:
WIPO Patent Application WO/2019/012882
Kind Code:
A1
Abstract:
This onboard sensor cleaning device comprises a nozzle opening (2a, 105a-108a), a pump (4, 109), a flow path, an on/off valve (5, 110), and a pressure accumulation section (6, 111, 146). The nozzle opening is provided in order to spray a fluid onto a sensing surface (1a, 101a-104a) of an onboard sensor (1, 101, 104). The pump feeds the fluid to the nozzle opening. The flow path communicates between the nozzle path and the pump. The on/off valve is provided to the flow path and opens/closes the flow path on the basis of a control signal. The pressure accumulation section is provided to a pump-side site, which is a site between the on/off valve and the pump in the flow path.
