20130294757 | PREFABRICATED ELECTRICALLY HEATABLE MEDIA LINE AND METHOD FOR PRODUCING A MEDIA LINE OF THIS KIND - In a prefabricated electrically heatable media line having at least one pipeline part with an integrated electrically conductive device and having at least one connecting device, in particular a plug, screw or coupling device, the pipeline part and the electrically conductive device extend as far as or close to that end of the connecting device which is averted from the pipeline part or close to, in front of or in a connection contour. In a method for producing a media line, a pipeline part is produced with at least one integrated electrically conductive device and the integrated electrically conductive device is exposed in at least one end region of the pipeline part, permanent electrical contact is made with said integrated electrically conductive part by a contact-making device, and the contact-making device is routed out at the outer face of the pipeline part in order to form a connection to an electrical energy source. | 11-07-2013 |
20130330065 | HEATABLE FLUID LINE, USE THEREOF AND METHOD FOR PRODUCING SAME - A heatable fluid line having a pipeline and an electrical heat conductor extending at least over a section of the pipeline. The pipeline has at least two longitudinal sections that are configured differently in respect of the material properties and/or design thereof. At least one first longitudinal section is formed of a first material and a second longitudinal section is formed of a second material. The material of the second longitudinal section is more flexible and/or has a higher resilience than the material of the first longitudinal section. A described method for producing the fluid line relates to an adaptive attachment of the heat conductor on the outside of the pipeline that permits the heat conductor to be wound around fluid coupling and/or connector parts, in particular the housings by means of which the line is assembled, without strand separation. | 12-12-2013 |
20130333772 | FABRICATED MEDIA LINE AND USE IN AN SCR CATALYST SYSTEM - An assembled media line, or a section of a media line, for connecting a tank to a dosing unit in order to add a reducing agent into a SCR catalyst system of an internal combustion engine. The fluid line has electric heating in some sections for heating of the fluid. The fluid line is additionally provided, at least in some areas, with fluid tempering. In use, the media line connects a tank to a dosing unit in order to add a reducing agent in a SCR catalyst system of an internal combustion engine, and wherein the engine coolant is used as tempering fluid. The tempering is achieved by inclusion of at least one tempering line running alongside the fluid line. A line connector for such a media line includes a connecting housing in which the fluid line and two tempering lines can be connected. | 12-19-2013 |
20140321841 | ASSEMBLED HEATABLE MEDIA LINE COMPRISING A MEDIA LINE HAVING AT LEAST TWO HEATING ELEMENTS ARRANGED ON THE EXTERIOR THEREOF, AND METHOD FOR THE PRODUCTION THEREOF - An assembled heatable media line having a media line having at least two heating elements arranged on the exterior of the media line and at least one line connector. In order to heat the at least one line connector, only one of the heating elements is arranged at or on said line connector and at least partially surrounds the same. A method for producing a heatable media line comprising the media line, at least one line connector and at least two heating elements is disclosed.
