Abstract: This pressure and temperature determining device includes a membrane, which has a face of contact with the fluid and a securing face opposite to the contact face, a pressure determining element secured to the membrane, and a temperature determining element secured to the membrane. The pressure determining element includes at least one piezoresistive track. The temperature determining element includes at least one thermoresistive track.

Abstract: This dampening device comprises a body defining a chamber and presenting at least one orifice intended for the inlet and the outlet of the fluid in the chamber. The dampening device further comprises i) a dampening member located in the chamber and comprising at least one foam with closed cells, and ii) a holding member configured to hold the dampening member in place. The dampening device being characterized in that at least one foam has a porosity comprised between 50% and 98%.

Abstract: This pressure and temperature determining device comprises a membrane (2) having a face (4) in contact with the fluid (F), a pressure determining element (6), a temperature determining element (10) and a support for supporting the temperature determining element (10). The support has an implantation face which is opposite to the contact face (4). The temperature determining element (10) is disposed on the implantation face (12).

Abstract: This pressure and temperature determining device (1) comprises a membrane (2), which has a face of contact (2.1) with the fluid and a securing face (2.2) opposite to the contact face (2.1), a pressure determining element (20) secured to the membrane (2), and a temperature determining element (40) secured to the membrane (2). The pressure determining element (20) comprises at least one piezoresistive track. The temperature determining element (40) comprises at least one thermoresistive track.

Abstract: A liquid additive reservoir including a rigid casing delimiting a housing, and a fluid-tight flexible pouch mounted inside the housing of the casing and intended to contain the liquid additive, the flexible pouch being designed to be connected to the exhaust line of an internal combustion engine of a vehicle.

Abstract: The device for injecting an additive comprises a removable flexible pouch forming a liquid additive reservoir connected to the fuel supply system of the engine via a quick-connect element to an additive feed line that supplies a dosing pump. The flexible pouch retracts whereby reducing its inside volume in order to compensate for the drop in pressure created inside as the additive is drawn out of the pouch. The flexible pouch is formed by two essentially oblong and rounded layers primarily made of thermoplastic polyurethane (TPU), in particular, ester-based whose perimeters forming lips are welded to one another by a weld bead. The invention is for use in direction injection diesel engines.
