The arm/wiper blade interface has a through-opening which connects the two fluid channels to each other. The heating wire is guided through the through-opening and the through-opening is closed with a sealing element.

A cleaning device for a surface, such as a windshield of a vehicle, has a housing that holds a spray bar, rotatable brush and a wiper blade. An engagement mechanism moves spray bar, the brush, and the wiper blade out from a disengaged position within the housing to an engaged position outside the housing so that they can be used to clean, brush, and dry the surface. After the spray bar, brush, and wiper blade are used to, respectively, clean, brush, and dry the surface, the engagement mechanism then moves the spray bar, the brush, and the wiper blade to a disengaged position within the housing.

A cleaning system for a sensor to be cleaned, comprising an accumulator comprising at least one cleaning fluid compartment provided with at least one tensioning element; a cleaning fluid inlet for receiving cleaning fluid; a cleaning fluid outlet for providing cleaning fluid in the form of a cleaning fluid jet; at least one gas compartment provided with at least one tensioning element; a gas inlet for receiving gas; and a gas outlet for providing gas in the form of a gas jet, a cleaning fluid electrovalve for controlling flow of cleaning fluid applied to the sensor to be cleaned, and a gas electrovalve for controlling flow of gas applied to the sensor to be cleaned.

A process (1) for de-icing a glazed surface (20) of a vehicle (2) is disclosed. A de-icing device (21) includes a wiper system (210) with at least one device for spraying a liquid (L, Lq), and is used to perform a method involving verification (E1) of a primary condition (C1) according to which the ignition (Cc) of the said vehicle (2) is activated, verification (E2) of a secondary condition (C2) according to which the exterior temperature (t) is below a temperature threshold (Th1), verification (E3) of a tertiary condition (C3) according to which a demisting function (fd) is activated; and when all of the conditions are fulfilled, then activation (E4) of the de-icing device (21) in order to start a de-icing cycle (Cy). The de-icing cycle (Cy) comprising spraying by the device for spraying of the liquid (L, Lq) onto the glazed surface (20).

A washer liquid heating device is provided. The device includes a heating unit that is positioned at a lower end of a reservoir. A washer pump is connected to one end of the heating unit and a controller adjusts a heat generation of the heating unit. Accordingly, at least some of washer liquid contained in the reservoir flows into the heating unit and is then discharged to the washer pump.

A system includes a dome, a wiper assembly, a position sensor and a control device. The wiper assembly includes a wiper blade configured to rotate around the dome. The position sensor may be configured to send a signal to a control device when a wiper blade passes the position sensor. The control device may include one or more processors configured to receive the signal from the position sensor and determine a location of the wiper blade relative to the dome based on the received signal.

A valve (1) for controlling a flow of a fluid comprises: – a valve body having at least one first body part (2) made of a moulded plastic material; – a chamber for passage of the fluid (6), defined within the first body part (2) and comprising at least one fluid inlet (6a) and at least one fluid outlet (6b); – a valve seat (7) defined within the chamber for passage (6) of the fluid; – means for shutting off the fluid (8-9), which can be displaced relative to the valve seat (7) in order to control flow of the fluid; and – a compensation element prearranged for compensating a possible increase in volume and/or pressure of the fluid. The compensation element comprises a compensation body (26) made of an elastically deformable and/or compressible material, the moulded plastic material of the first body part (2) being stiffer than the elastically deformable and/or compressible material. The first body part (2) defines a tubular portion (23) that extends between the valve seat (7) and one of the inlet (6a) and the outlet (6b), within the chamber for passage of the fluid (6). The compensation body (26) is mounted within the chamber for passage of the fluid (6) so as to surround the tubular portion (23) at least partially.

A vehicle travel control system installed on a vehicle includes: a recognition sensor configured to recognize a situation around the vehicle; a sensor cleaning device configured to clean the recognition sensor; and a control device configured to execute vehicle travel control based on result of recognition by the recognition sensor, and to actuate the sensor cleaning device to execute sensor cleaning processing that cleans the recognition sensor. The control device permits execution of the sensor cleaning processing in a situation where decrease in recognition performance has a small influence on the vehicle travel control. For example, when a surrounding vehicle recognized by a first recognition sensor is also recognized by a second recognition sensor, the control device permits execution of the sensor cleaning processing that cleans the first recognition sensor.

Described is a windshield wiper apparatus that is formed to dispense fluid. The wiper apparatus includes an elongate body member having a length with a sealable channel therein that runs along the length. At least one blade protrudes downward along the length of the elongate body member. Further, a series of holes are formed such they pass from the sealable channel and through the elongate body member proximate the at least one blade. Thus, a fluid passing through the sealable channel is dispensed onto a surface proximate the at least one blade.

A cleaning device for a vehicle provides a liquid cleaning pulse and/or a compressed air cleaning pulse for a cleaning nozzle. The cleaning device includes a module compressed air connection for receiving compressed air and a pressure cylinder with a cylinder volume. A movable separator divides the cylinder volume into a compressed air receiving chamber and a cleaning liquid receiving chamber in a fluid tight manner. The air chamber has an air chamber connection which can be supplied with compressed air. Contraction of the liquid chamber occurs when filling the air chamber by moving the separator against a restoring force. A switching valve establishes a pneumatic connection between the module compressed air connection and the air chamber connection. A bypass valve establishes a pneumatic connection between the module compressed air connection and the compressed air nozzle line while bypassing the switching valve for providing a bypass compressed air flow.
