摘要： There is disclosed a valve assembly for washing cameras or sensors of an autonomous vehicle. The valve assembly includes a single fluid injector having a fluid inlet, a fluid outlet, and a fluid passage in fluid communication with the fluid inlet and the fluid outlet. A cup is disposed over an upstream portion of the fluid injector, relative to a direction of fluid flow through the fluid injector. A lower housing is disposed over and surrounds a downstream portion of the fluid injector, relative to the direction of fluid flow therethrough. A bracket member extends from the lower housing. The bracket member is configured for connecting to an anchor member for attachment within the autonomous vehicle. In this way, the valve assembly may be easily secured within a vehicle for providing a desired amount of fluid to the lens of the vehicle camera or sensor.

摘要： A fluid injector includes a fluid inlet, a fluid outlet, and a fluid path from the fluid inlet to the fluid outlet. An actuator unit is disposed within the fluid injector. A valve assembly operatively couples to the actuator unit. A spacer member is disposed between a downstream end portion of the actuator unit and a portion of the valve assembly, the spacer member constructed from a compressible, resilient material so as to compress due to expansion forces from fluid in the fluid injector freezing, and to expand when frozen fluid in the fluid injector melts. The spacer member occupies a space in the fluid path of the fluid injector.

摘要： A fluid injector includes a calibration filter tube including a bore defined in an axial direction through the calibration filter tube, the bore defining at least a portion of a fluid path through the fluid injector, the calibration filter tube including a plurality of holes which extend from the bore to an outer surface of the calibration filter tube. A volume reduction member has a bore though which the calibration filter tube extends, the volume reduction member occupying a space between the outer surface of the calibration filter tube and an inner surface of the tube member, the volume reduction member being constructed from resilient, compressible material. Freezing or frozen fluid disposed in the calibration filter tube expands through the holes and at least partially compresses the volume reduction member, so as to reduce fluid expansion forces damaging other components of the fluid injector.
