A cleaning device for supplying a medium pulse to a surface includes a pressure cylinder having a pressure connection, a medium connection, and a first nozzle connection. The volume of the pressure cylinder is divided into a first medium chamber and a second medium chamber and volumes thereof are configured to be changed. A switching valve is configured to switch between a first switching state and a second switching state. In the first switching state, the first medium chamber is connected to the first medium source to reduce the volume of the second medium chamber, and in the second switching state, the first medium chamber is connected to the second nozzle connection to increase the volume of the second medium chamber such that the surface can be supplied with the medium pulse.

A wiper arm adapter device with at least one fluid channel (44a, 46a; 44b, 46b) for conducting a fluid, and with at least one connecting unit (48a; 48b) for connecting the fluid channel (44a, 46a; 44b, 46b) to a fluid line element (36a; 36b) of a wiper arm and/or to a wiper blade adapter (30a; 30b), wherein the connecting unit (48a; 48b) has at least one connecting element (52a, 54a; 52b, 54b) which at least partially delimits the fluid channel (44a, 46a; 44b, 46b). The connecting unit (48a; 48b) has at least one valve element (56a, 58a; 56b, 58b) which is arranged on the connecting element (52a, 54a; 52b, 54b) and is configured to form the fluidic connection of the fluid channel (44a, 46a; 44b, 46b) to the wiper blade adapter (30a; 30b) in a closeable manner.

A vehicle which contributes to safe autonomous driving by washing the sensor provided in the vehicle by efficiently using a limited capacity washing solution, and a control method thereof. The vehicle includes: a first sensor; a second sensor; a driving device including at least one motor and configured to operate to clean the first sensor and the second sensor; and a controller configured to control the driving device to first wash the first sensor prior to the second sensor based on predetermined rank information when is the controller determines that at least one of the first sensor and the second sensor is contaminated.

The present invention relates to a system for cleaning at least two sensors/transmitters for a motor vehicle, the system comprising at least one first device for projecting a cleaning fluid onto at least one first sensor/transmitter, at least one second device for projecting a cleaning fluid onto at least one second sensor/transmitter, at least one reservoir, at least one circuit for distribution of the cleaning fluid, connecting the reservoir to the first and second projection devices, at least one electronic pump, and at least one control unit, characterized in that the control unit is configured to receive information on a request for activation of the first and/or second projection device(s) in order to determine a theoretical value of at least one operating parameter of a pump.

Of the moving directions of the piston, the direction in which high-pressure air is delivered is a delivery direction, and the direction in the opposite direction from the delivery direction is a force accumulation direction. The piston is moved in the force accumulation direction by the moving mechanism, and moved in the delivery direction by the biasing force of the biasing spring in response to the release of the moving force exerted by the moving mechanism. The cylinder is provided with: a piston supporting portion that supports the piston; and a connection protrusion that has a delivery path for delivering the high-pressure air to the nozzle. The inner surface of an end of the piston supporting portion in the delivery direction is formed as a closed surface. The delivery path is located further toward the force accumulation direction than the closed surface is.

A windscreen washer system for vehicles, in particular for motor vehicles, including at least one rainwater collection element connected to at least one suction pump for collecting rainwater and conveying the same to a collection tank connected in turn to a pump for delivering windscreen washer fluid where the rainwater collection element is integrated in at least one wiper blade.

The on-board sensor cleaning apparatus is applied to a vehicle having a front camera, a rear camera, a center display, and an electronic inner mirror. A surrounding image obtained through the front camera and the rear camera is displayed on the center display and the electronic inner mirror. The on-board sensor cleaning apparatus includes an ECU, a position information obtaining device, and a cleaning unit. The ECU obtains a visual check probability for an area which includes a position of the vehicle indicated by vehicle position information, from a database. The ECU sets an automatic cleaning start condition based on the obtained visual check probability.

A vehicular cleaner system (1) for cleaning a to-be-cleaned object (100), wherein: the vehicular cleaner system (1) is provided with a tank (11) that accommodates a cleaning liquid, a pump (12) that pressure-feeds the cleaning liquid inside the tank (11), a high-pressure-air generation unit (2) that generates high-pressure air, a first ejection port that sprays the cleaning liquid toward a cleaning surface of the to-be-cleaned object (100), a second ejection port that sprays the high-pressure air toward the cleaning surface, and a controller (4) and vehicle ECU (40) that control the spraying of the cleaning liquid and the spraying of the high-pressure air; and the controller (4) and the vehicle ECU (40) perform control so as to initiate the spraying of the high-pressure air from the second ejection port after spraying of the cleaning liquid from the first ejection port has been initiated.

The present invention for rights for a system configured for use with an existing motor vehicle windshield washer system whereby a portion of solution is directed to a headlamp washing outlet.

A washer liquid supply valve includes a valve body provided with an inflow hole and a discharge hole configured to allow a washer liquid to flow into and out of the valve body therethrough, a housing detachably combined with an upper part of the valve body, a coil assembly installed in the housing and configured to generate magnetic force when power is applied to the washer liquid supply valve, a core combined with the coil assembly while penetrating the coil assembly and magnetized by the magnetic force generated by the coil assembly, plunger installed in the core so as to be movable and configured to be moved upwards when power is applied to the washer liquid supply valve, and a spring interposed between the core and the plunger so as to elastically support the plunger towards the valve body.
