Abstract
A fuel filler device that includes a flow conduction device arranged in a filler line and configured such that during a filling, an outlet pipe of a pump nozzle is guided and supported therein, and an attachment connected to the flow conduction device. The attachment includes a first attachment end, a second attachment end, and a constriction extending between the first attachment end and the second attachment end such that the attachment tapers from the first attachment end to the second attachment end via the constriction. At least one first gap is formed between the first attachment end and the flow conduction device so that during a filling sequence, fuel vapour introduced into the fuel filler device may flow through the at least one first gap into the filler line in a direction of a fuel tank connected to the filler line.
Claims17
A fuel filler device, comprising:
- a flow conduction device arranged in a filler line to guide and support an outlet pipe of a pump nozzle during a filling sequence;
- and
- an attachment connected to the flow conduction device, the attachment including a first attachment end, a second attachment end, and a constriction extending between the first attachment end and the second attachment end,
- wherein the first attachment end includes at least one spacer rib that extends radially inward towards the flow conduction device to position the attachment relative to the flow conduction device and define at least one gap between the first attachment end and the flow conduction device to relieve pressure during a filling sequence by facilitating flow of fuel vapour introduced into the fuel filler device into the filler line in a direction of a fuel tank which is connected to the filler line.
A fuel filler device, comprising:
- a flow conduction device arranged in a filler line to guide and support an outlet pipe of a pump nozzle during a filling sequence;
- and
- an attachment connected to the flow conduction device, the attachment including a first attachment end and a second attachment end, the first attachment end include a plurality of spacer ribs that extend radially inward towards the flow conduction device to position the attachment relative to the flow conduction device and define a plurality of gaps between the first attachment end and the flow conduction device that are configured to relieve pressure during a filling sequence by facilitating flow of fuel vapour introduced into the fuel filler device into the filler line in a direction of a fuel tank which is connected to the filler line.
A fuel filler device, comprising:
- a flow conduction device arranged in a filler line to guide and support an outlet pipe of a pump nozzle during a filling sequence;
- and
- an attachment body connected to the flow conduction device, the attachment body tapering between a first attachment body end and a second attachment body end, the first attachment body end include a plurality of spaced apart spacer ribs that extend radially inward towards the flow conduction device to define a plurality of gaps that are configured to relieve pressure during a filling sequence by facilitating flow of fuel vapour introduced into the fuel filler device into the filler line in a direction of a fuel tank which is connected to the filler line.
