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.

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.

Fluid distribution valve (11), particularly for a vehicle screen wash system, characterized in that it comprises a body (41) defining a duct (43) for the passage of fluid and comprising at least one fluid inlet (45) and at least one fluid outlet (47, 49), a membrane (53) housed in the duct and configured to be deformed under the action of a magnetic field between a first position of at least partial closure of the duct and a second position of at least partial opening of the duct, and means (51) for generating a magnetic field within the duct in order to cause the membrane to deform.

A washer liquid heating apparatus integrated into a reservoir may include an auxiliary tank which is integrally connected to the reservoir and in which a washer liquid inflowing from the reservoir is stored, and a heater assembly that is integrally attached to the auxiliary tank and heats the washer liquid stored in the auxiliary tank, wherein the heater assembly comprises a plate-type heater that is installed in a hole of the auxiliary tank to heat the washer liquid within the auxiliary tank, and wherein the plate-type heater is exposed to an inside of the auxiliary tank through the hole of the auxiliary tank such that a heating surface where heating is performed heats the washer liquid within the auxiliary tank.

A nozzle assembly (18) for a windshield washer system or the like provides an elongate heater element (30) that can extend along a supply tube connected to the washer nozzle (20) to better transfer heat energy into the washer fluid and the nozzle for preventing nozzle clogging caused by low temperatures.

A hydraulic interface configured to be installed between a windscreen washer liquid feed tube and a connector of a device for wiping a window of a motor vehicle is disclosed. The interface includes a body that defines at least one passage channel for the windscreen washer liquid, and at least one electric heating conductor that is disposed so as to heat said windscreen washer liquid, said body being configured to secure said conductor to said body by fitting together different parts of said body and/or by fitting to shapes made in one piece with said body.

A washer fluid heating device includes a container that contains a washer fluid, a lid portion attached to a first end of the container to face an accommodation space for the washer fluid, heating means that has a proximal end portion attached to the lid portion and extends toward the accommodation space, and an outflow pipe having an outlet disposed in the accommodation space to allow the washer fluid in the accommodation space to flow out, and the outlet of the outflow pipe is provided such that a space formed between a horizontal plane passing through the outlet and an inner wall surface at a second end on an opposite side to the first end of the container corresponds to 10% or more of a volume of the accommodation space.

A safety device for heating hoses is provided to prevent overheating of a heating wire. The safety device includes a first hose that connects between a reservoir and a connector and a second hose that is fluidly connected to the first hose and allows windshield washer fluid to flow from the connector to a spray nozzle. A housing encloses the connector and a heating wire is disposed in at least one of the first and second hoses. A terminal is disposed inside the housing and is connected to the heating wire to apply electric power from a power supply unit to the heating wire. A circuit breaker is connected to the terminal and the heating wire and cuts off electric power applied to the heating wire based on a temperature condition.

A heating device intended to heat body, such as fluid contained in fluid circuit, the device including at least one electric heating element, as well as at least one control module to electrically power the heating element, the heating element being formed by propulsive winding circuit of direct-current electric motor which, when it is electrically powered by a direct supply voltage, generates drive force which tends to drive the motor in direction of displacement determined by the polarity of the supply voltage, and the control module including activation mode called heating oscillating mode, according to which the control module causes a warm-up of the propulsive winding circuit by Joule effect by applying at the terminals of the winding circuit an alternating supply voltage whose polarity switches, alternately and automatically, according to predetermined frequency called heating frequency, from a first polarity to opposite second polarity.
