Definitions

• the present invention relates to a sealing element.
• the invention relates to a sealing element such as a dehydrator filter or accumulator destined for a cooling device for a conditioning plant such as a conditioner or climatizer for vehicles.
• dehydrator filters or accumulators for conditioning plants and in particular for motor vehicles are assembled by welding the cap to the tubular body.
• This system requires the use of metallic elements and necessitates a welding operation for assembling these with all the drawbacks of cost, waste-products and com- plexity of the components involved.
• a general objective of the present invention is to provide a sealing element such as a dehydrator filter or accumulator for a cooling system of a conditioning plant by means of assembly without welding between the components and which obtains properties of sealing and lightness which are necessary for the particular use as a de- hydrator filter or accumulator for a conditioning plant to be assembled in a vehicle.
• the sealing element in the form of a dehydrator filter or accumulator according to the present invention is envisaged for a cooling device for a conditioning plant and comprises a tubular element, reclosable at one or both ends, by means of a cap destined for being at least partially inserted inside the tubular element, the closure obtained by the cap acting as a seal by means of at least a first annular portion of the tubular element, suitable for being inserted inside a corresponding annular seat situated along the surface of the cap, and a truncated-conical brim produced at the end of the tubular element and suitable for coming into contact with a corresponding truncated-conical annular neck situated along the outer surface of the cap.
• a sealing element 10 in the form of a dehydrator filter or accumulator, destined for a cooling device for a conditioning or climati- zation plant, in particular but not exclusively for motor vehicles, comprises a metallic or plastic tubular element 11, having one or both of the two ends 12 reclosable by means of a cap 20 made of plastic or a light metal.
• the cap 20 can be produced in the form of a "blind" lid or it can comprise a longitudinal outlet duct 21 whose internal mouth is optionally equipped with a fil- tration element 22 and an inlet duct 23 substantially- parallel to the outlet duct, said ducts can also be used as seats for the insertion of possible tubes.
• the cap 20 is destined for being at least partially inserted inside the tubular element 11, by means of an insertion portion 27 having a smaller diameter to which a counterpart portion 28 having a larger diameter is connected, and withheld therein effecting a seal thanks to the sealing means consisting of: - at least a first annular portion 14 which extends to- wards the inside of the tubular element 11 close to the end of the tubular element itself, said first annular portion being suitable for being inserted inside a corresponding first annular seat 24 situated along the surface of the cap 20; and - a truncated-conical brim 16 situated at the end of the tubular element 11 and suitable for coming in contact with a corresponding truncated-conical annular neck 26 situated along the outer surface of the cap.
• the cap preferably has a second annular portion 15 which extends towards the inside of the tubular element 11 and is axially arranged in a more internal position with respect to the first annular portion.
• Said second annular portion is suitable for being inserted inside a corresponding second annular seat 25 situated along the surface of the cap 20.
• an elastic ring 17, an O-RING can be inserted for increasing the seal.
• the sealing element according to the invention can also have, if necessary the function of a flow stabilizer of the cooling agent at the inlet optionally effected with specific flow deflectors 29.
