Fuel line for use in engine compartment of motor car, is designed such that cross section area of line is larger during operation of combustion engine than during stopped condition of combustion engine
摘要
<p>The line (1) is designed such that cross section of the line is variable in a portion upstream of a feed device to a combustion engine by action of forces. Cross section area of the line is larger during operation of the combustion engine than during stopped condition of the combustion engine. A spring element (2) acts in a wall of the line, where the line exhibits an elliptical cross section in the presence of sufficient pressure in the line. The line exhibits circular cross section in the presence of excess pressure (P1) in the line.</p>
