Abstract: A multilayer hose is provided for use in vehicle air conditioning systems in particular for the transport of low environmental impact coolants such as fluoropropenes. According to the present invention the hose comprises a first inner layer comprising PPA or semiaromatic polyamide. The hose furthermore comprises at least one second layer comprising an elastomeric material.

Abstract: A coolant adducting assembly for a climate control system of a vehicle comprises a joint and a pipe connected to the joint, wherein pipe and joint comprise a thermoplastic material and the joint comprises an insert made of a more rigid material than the thermoplastic material and has an anchoring portion co-molded into the joint and a connecting portion exiting the joint and adapted to be firmly connected to a device.

Abstract: A piping for an SCR circuit of a motor vehicle comprising a pipe to feed a solution comprising urea, an electrical resistor surrounding the pipe to heat the solution containing urea, and a layer of a material having a flexural stiffness higher than that of the pipe, in which the layer is tubular and houses at least partially the electrical resistor and the pipe.

Abstract: A fuel vapor adsorbing device has a casing having an axis and defining a vapor inlet, a vent connected to the outside environment, and a chamber connected fluidically to the inlet and the vent. The adsorbing device also includes a filter material housed in the chamber; a cover wall covering the chamber; and an elastic mechanism and, preferably, a grille, which are integral with the cover wall and cooperate with the filter material.

Abstract: A bracket for attaching a hose comprising a strip adapted to surround a hose, an end portion connected to the strip and a locking portion to close the strip about the hose, in which the locking portion is configured to cooperate with a threaded fastening device to fasten the bracket to a support is provided. The bracket further comprises at least one anti-rotation device adapted to cooperate with one of the threaded fastening device and the support.

Abstract: A motor vehicle fuel conveying multi-layer co-extruded tube (1) comprising at least an innermost first layer (2) of a polyamide resin (P9T) consisting of a dicarboxylic acid component and a diamine component, wherein 60÷100% of the dicarboxylic acid component is terephthalic acid and 60÷100% of the diamine component is selected from 1,9-nonanediamine and 2-methyl-1,8-octanediamine; an intermediate second layer (3) of polyamide 6 (PA 6); an intermediate co-polyamide (CoPA)-based tie layer (4); and an external fourth layer of polyamide 12 (PA12).

Abstract: A fluidic assembly for an air conditioning circuit comprises a first feeding line for a high temperature fluid, a second feeding line comprising a barrier material for a refrigerating fluid in the gaseous state, and a casing defining a first inlet and a first outlet connected to the second line; a chamber having an elongated shape and a minimum upper cross dimension as compared to the first inlet and second outlet; a second inlet and a second outlet connected to the first line; the fluidic assembly comprising a radiating body adapted to be crossed by the high temperature fluid and fluid-tightly connected to the casing between the second inlet and the second outlet within the chamber for defining an integrated silencer-exchanger assembly.

Abstract: A multilayer hose for conveying an aqueous solution containing urea including a conveying pipe of the fluid, a heating element and an insulating layer. The heating element is a tubular braid or mesh or net element in which at least one wire is formed by a conductive material and one strand is formed by thermoplastic material.

Abstract: A joint for a refrigerant adduction circuit defines a seat adapted to house an o-ring and comprises a first annular projection defining a first inclined surface tapered towards the seat, a second annular projection defining a second inclined surface tapered towards the seat, in which the first annular projection is axially between the seat and the second annular projection.
