Abstract
The invention relates to a fluid line (1), comprising a pipe (2), which has an inlet-side end segment (3) having a first connector (5) and an outlet-side end segment (4) having a second connector (10), wherein a cavity (17) bounded in the radially inward direction by at least one auxiliary element (16) is formed in the pipe (2). The problem addressed by the invention is that of minimizing the requirements for the suction performance of a pump that is used to convey a liquid through the pipe. This problem is solved in that a volume reduction element (18) is arranged in the cavity (17) at least in the region of the outlet-side end segment (4).
Claims9
A fluid line comprising:
- a pipe which has an inlet-side end portion with a first connector and an outlet-side end portion with a second connector;
- at least one auxiliary element arranged in the pipe to form a radial inside wall of a radially delimited cavity, the pipe forming a radial outside wall of the cavity;
- and
- a volume reduction element being arranged in the cavity, at least in the region of the outlet-side end portion,
- wherein the volume reduction element has a recess extending along a length of the pipe to form a continuous flow channel,
- wherein the at least one auxiliary element comprises a heating rod,
- wherein the first connector has a first stub onto which the pipe is pushed and a connection geometry which is connectable to a pump,
- wherein the second connector has a second stub onto which the pipe is pushed and a connection geometry which is connectable to an injection device, and
- wherein the volume reduction element comprises at least a first axial portion that lies against the radial inside wall of the cavity and another axial portion that lies against the radial outside wall of the cavity.
