According to the invention, the valve unit (14a; 14b) is designed for integration into a wiper arm tube unit (18a; 18b).

A device is described for protecting a sensor window. The device includes a two-piece nozzle system and is configured for generating a first and a second fluid flow, a first piece of the two-piece nozzle system being fixedly situated with respect to the sensor window, and a second piece of the two-piece nozzle system being configured for assuming different positions with respect to the first piece of the two-piece nozzle system, and the two-piece nozzle system being aligned with respect to the sensor window to direct a predominant portion of the first fluid flow in parallel to the sensor window and to direct a predominant portion of the second fluid flow in the direction onto the sensor window.

An on-vehicle sensor cleaning device includes a cleaning actuator that cleans a cleaning object surface an on-vehicle sensor, the cleaning object surface being cleaned by operating the actuator; and a controller that drives the cleaning actuator when fouling degree information of the cleaning object surface reaches a fouling threshold. The controller is configured to change the fouling threshold depending on a vehicle speed information.

Disclosed is an arrangement of nozzle units for a wiper arm, wherein at least one nozzle unit comprises a rigid body, has a channel through which liquid can flow into the nozzle unit and/or out of the nozzle unit, and comprises a nozzle, which is connected to the channel. The nozzle units are in communication with each other in series such that a liquid can flow from a nozzle unit into a following nozzle unit in the series, wherein at least one nozzle unit has a contact surface which is formed such that the nozzle unit cannot rotate about the longitudinal axis thereof if the contact surface contacts a surface of a wiper arm. A wiper arm comprising the arrangement is also disclosed.

The invention relates to a wiper arm device, in particular a windscreen wiper arm device, comprising: at least one hose-holding unit (12) which can be mounted on at least one wiper arm (10) and which comprises at least one hose guide (14) provided for guiding at least one washing water hose (16); at least one auxiliary nozzle unit (18); and at least one coupling unit (20) which is provided to couple the auxiliary nozzle unit (18) to the hose-holding unit (12) and comprises at least one first coupling element (22) and at least one corresponding second coupling element (24) for coupling. According to the invention, the first coupling element (22) is formed at least in part by the hose guide (14).

A sensor assembly includes a first sensor window defining a first plane, a second sensor window fixed relative to the first sensor window and defining a second plane different than the first plane, and a nozzle positioned to deliver fluid to the first and second sensor windows. The nozzle is translatable along a first axis, rotatable about the first axis, and rotatable about a second axis transverse to the first axis.

A device which is designed to detect surroundings and which includes a housing and a sensor situated within the housing. The housing includes a transmitter/receiver window, through which the corresponding sensor signals may be emitted into the surroundings by the sensor, and/or sensor signals from the surroundings may be received. The device includes a cover, the cover being designed to be transparent to the sensor signals, and the cover being designed to cover the transmitter/receiver window against exterior surroundings of the device. The device includes a cleaning unit, which is situated at an outside of the housing and is movable relative to the housing using a drive unit. The cleaning unit is designed to remove contaminants from the cover. The cleaning unit includes at least one first nozzle to spray a cleaning liquid onto the cover, and at least one second nozzle to blow a gas onto the cover.

An aircraft windshield wiper system includes a wiper arm, a wiper blade coupled to a first end of the wiper arm, and an output shaft coupled to a second end of the wiper arm. The wiper blade includes a fluid dispensing system including nozzles, a fluid control unit, fluid lines, fluid source, and a user interface. The wiper blade with the fluid dispensing system is configured to dispense a variety of fluids directly from the wiper blade onto the windshield of an aircraft.

A windshield wiper arm includes: an arm piece to which a wiper blade wiping a wiping surface is connected; a hose supplied with washer fluid; and a washer nozzle connected to the hose and mounted on the arm piece on the base end side with respect to a portion connected to the wiper blade. The washer nozzle includes: a first flowpath extending in a longitudinal direction; a second flowpath connected to the first flowpath and extending in a wiping direction which intersects the longitudinal direction, and in which the wiper blade can move when wiping the wiping surface; a third flowpath connected to the second flowpath and extending in a vertical direction which is along a normal line of the wiping surface while intersecting the longitudinal direction and the wiping direction; and a fitting groove into which the arm piece is fitted and which extends along the longitudinal direction.

A windshield cleaning assembly for a vehicle includes a wiper that is operationally coupled to a wiper motor of a vehicle. A pipe is coupled to the wiper and extends from proximate to opposing ends of a blade of the wiper. The pipe has a first end that is closed. A pump is coupled to the vehicle is operationally coupled to an electrical circuit of the vehicle. A tank is coupled to the vehicle and is fluidically coupled to the pump. The tank is configured to position a fluid. A tube is fluidically coupled to and extends between the pump and a second end of the pipe. The pump is positioned to selectively pump the fluid from the tank through the tube and the pipe. The fluid exits the pipe under pressure through a plurality of holes to clean the windshield.
