Abstract
Disclosed in a heatable fluid line (1) comprising a tube (2) with an interior, and a heating device (3) inside the interior. The aim is to protect an injection arrangement, which is connected to the fluid line (1), at low temperatures. In order to achieve said aim, a volume reducing element (5) is disposed between the tube and the heating device (3).
Claims13
A heatable fluid line comprising:
- a pipe which has an inner space;
- a heating device which is constructed as a heating rod and is arranged in the inner space to delineate an annular gap between the pipe and heating device;
- and
- a volume reduction element arranged in the annular gap so that an annular portion of the annular gap remains between the volume reduction element and the pipe for a heatable fluid to flow through the pipe between the volume reduction element and the pipe,
- wherein the volume reduction element is constructed as a pipe piece having a cover with a cut in a longitudinal direction and a recess, which is formed by the cut in the cover of the volume reduction element in the annular gap, extends along the heating device,
- wherein the recess produces a region configured for the heatable fluid to flow through between the heating rod and the pipe, and
- wherein the volume reduction element is clip-fitted onto the heating rod.

A heatable fluid line comprising:
- a pipe which has an inner space;
- a heating device which is constructed as a heating rod and is arranged in the inner space to delineate an annular gap between the pipe and heating device;
- and
- a volume reduction element, which is arranged in the annular gap, includes a longitudinal cut, so that facing sides of the longitudinal cut are separatable to clip-fit the volume reduction element onto the heating device,
- wherein, when the volume reduction element clip-fitted onto the heating device is arranged in the annular gap, a recess, formed between the facing sides of the volume reduction element, extends along a length of the volume reduction element for guiding a heatable fluid flow between the heating device and the pipe.
