The object of the invention is a heater of a corrosive fluid comprising at least one heat diffuser having at least a first portion intended to be immersed in a corrosive fluid, and at least a second portion intended to be arranged out of the corrosive fluid, at least one heating block comprising at least one heating member configured to heat the corrosive fluid, said heat diffuser comprising at least one housing in which the at least one heating block is housed at least partially, at least the first portion of the heat diffuser being made of anodized aluminum or of anodized aluminum alloy and is configured to be in direct contact with the corrosive fluid. The object of the invention is also a corrosive fluid tank comprising a heater according to the invention and a method for manufacturing a heat diffuser of the heater according to the invention.

Corrosive fluid heater, tank and manufacturing method

The invention concerns a circuit intended to transfer, by means of a pump, first fluid, such as an aqueous urea solution, from a reservoir to an injector, said circuit also containing a second fluid, such as air, and said circuit comprising, downstream of the pump and of the reservoir, a downstream circuit portion which includes, on the one hand, a main branch which leads to the injector and, on the other hand, bypass branch which returns to the reservoir and which is provided with a double-seat valve designed to selectively and automatically adopt: purge configuration allowing to purge the second fluid through the valve out of the main branch, a pressurized supply configuration allowing to direct the first fluid to the injector under a predetermined working pressure, and a recirculation configuration allowing a recirculation through the bypass branch, and to the reservoir, of the first fluid coming from said reservoir.

Urea depollution circuit comprising a double-seat valve selectively ensuring the degassing or the recirculation of the aqueous urea solution

This valve includes a first chamber, a second chamber, a seat with a liquid passage, a plug movable between i) an open position and ii) a closed position, and a biasing member for urging the plug toward the closed position. The valve includes an actuating member having a face which sustains an actuating pressure. The actuating member is movable between i) an actuation position for opening the plug and ii) a rest position. The valve operates, selectively: in a feed mode, where the plug is open and the actuating member is at rest, the liquid flowing in one direction throughout the second chamber, or in a latch mode, where the plug is closed and the actuating member is at rest, no liquid flowing in the valve, or in a drain mode, where the plug is open, the liquid flowing in the reverse direction throughout the second chamber.

Valve connected to a feed circuit, a feed circuit comprising such a valve and a feeding method operating such a feed circuit

This reservoir assembly includes a reservoir, a liquid supply module of a downstream pipe, and a level sensor. The bottom has a first protruding portion, for housing the supply module, and a second protruding portion for defining a passage housing the downstream pipe. The level sensor is located in the housing. The bottom further has an upper area and a lower area adjacent to the housing. The upper area is defined by a top portion of the passage. The lower area is located lower than the upper area. The level sensor is in the housing at the same altitude as the lower area.
