Document Type and Number:
WIPO Patent Application WO/2018/135322
Kind Code:
A1
Abstract:
The present invention comprises: a flow passage for connecting a suction section and a discharge section; a cylinder for connecting a pressure chamber in front of a piston to a flow passage; a piston drive mechanism including a motor; a first valve located between the suction section and the pressure chamber and functioning such that the first valve opens when the piston moves backward and closes when the piston moves forward; a second valve located between the pressure chamber and the discharge section and functioning such that the second valve opens when the piston moves forward to bring pressure inside the pressure chamber to a predetermined value; and a casing for containing the flow passage, the cylinder, the piston drive mechanism, the first valve, and the second valve and combined with a vehicle camera so that fluid discharged from the discharge section will be sprayed on the light incident section of the vehicle camera.
