초록 ▼

A cap-free closable neck end for a filler neck of a tank of a motor vehicle may include an upper entry space forming an insertion region for a fuel nozzle and being surrounded by a side wall, a lower sealing flap arranged in the upper entry space and closing mechanism arranged above the lower sealing flap, which includes an upper filling opening and an upper cover, which in a closed state at least partially covers the upper filling opening, and such that the upper cover is displaced by inserting an outlet pipe of a fuel nozzle into the upper entry space for releasing the upper filling opening to allow for the insertion of the outlet pipe through the upper filing opening and the lower sealing flap.

대표청구항 ▼

1. A filler system of a tank of a motor vehicle, comprising: a pipe, the pipe including an upper pipe section and a lower pipe section, wherein a cross-section of the upper pipe section widens in a conical manner in a direction of an opening at an end of the upper pipe section opposite the lower pipe section;an upper filling opening at a lower end of the upper pipe section;a lower sealing flap arranged in the lower pipe section;a closing mechanism arranged above the upper filling opening and configured to prevent insertion of a fuel nozzle without opening the closing mechanism;and a pipe connection configured to connect the lower pipe section to a tank filler neck leading to the tank of the motor vehicle, wherein the tank filler neck is disposed between the lower pipe section and the tank of the motor vehicle when the lower pipe section is connected to the tank filler neck, wherein the pipe connection is designed to be released using a special tool specifically designed for the purpose of releasing the pipe connection and disengaging the lower pipe section from the tank filler neck, wherein attempting to release the pipe connection without using the special tool will result in destruction of the pipe connection,wherein the pipe connection is formed by resilient holding elements that are arranged between an end of the tank filler neck and the pipe connection, and wherein the resilient holding elements are configured to be displaced when the end of the tank filler neck is slid into the pipe connection, wherein holding edges of the resilient holding elements are configured to resiliently engage with respective accommodations to form a positive connection and being designed such that the holding edges wedge automatically in response to a stress in a direction of attempting to pull the pipe connection off the end of the tank filler neck, and wherein the resilient holding elements are configured to engage in recesses located proximate to the end of the tank filler neck during or after pushing or screwing the pipe connection onto the end of the tank filler neck and are configured to be retracted from the recesses using the special tool. 2. The filler system of a tank of a motor vehicle according to claim 1, wherein the upper pipe section includes: an upper cover that is configured to at least partially cover the upper filling opening when the upper cover is in a closed state, and which is embodied in such a manner that the upper cover is configured to be displaced by inserting an outlet pipe of a fuel nozzle into the opening at the end of the upper pipe section to release the upper filling opening to allow for the insertion of the outlet pipe through the upper filling opening and the lower sealing flap. 3. The filler system of a tank of a motor vehicle according to claim 1, wherein the pipe connection includes an open snap ring, and wherein the pipe connection is configured such that the special tool is able to be slid between a wall of the pipe connection and the end of the tank filler neck, and wherein the pipe connection is configured such that the special tool is then able to contract two ends of the open snap ring and override engagement of the resilient holding elements in the recesses. 4. A filler system of a tank of a motor vehicle, comprising: a pipe, the pipe including an upper pipe section and a lower pipe section, wherein a cross-section of the upper pipe section widens in a conical manner in a direction of an opening at an end of the upper pipe section opposite the lower pipe section;an upper filling opening at a lower end of the upper pipe section;a lower sealing flap arranged in the lower pipe section;a closing mechanism arranged above the upper filling opening and configured to prevent insertion of a fuel nozzle without opening the closing mechanism;and a pipe connection configured to connect the lower pipe section to a tank filler neck leading to the tank of the motor vehicle, wherein the pipe connection is formed by a single snap ring, and wherein the tank filler neck is disposed between the lower pipe section and the tank of the motor vehicle when the lower pipe section is connected to the tank filler neck. 5. The filler system of a tank of a motor vehicle according to claim 4, wherein the snap ring is disposed between an inner wall of the lower pipe section and an outer wall of the tank filler neck. 6. The filler system of a tank of a motor vehicle according to claim 4, wherein the snap ring comprises ends configured to be pressed together or pulled apart. 7. The filler system of a tank of a motor vehicle according to claim 4, further comprising an O-ring disposed between an inner wall of the lower pipe section and an outer wall of the tank filler neck and configured to provide a seal between the lower pipe section and the tank filler neck.
