Title:
AUTOMOBILE FUEL IN-TANK TUBE AND METHOD OF MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2011/114865
Kind Code:
A1
Abstract:
Disclosed is an in-tank tube with superior pressure resistance performance. A monolayer structure automobile fuel in-tank tube (1) is disposed within a fuel tank (2), and comprises a configuration of absorbing the displacement of the fuel tank (2) and the oscillations of a fuel pump (5). The automobile fuel in-tank tube (1) is formed in a monolayer structure from a resin material, the primary constituent thereof being an aliphatic polyamide resin, said in-tank tube (1) further comprising a pressure-resistant characteristic (X) described hereinafter:
(X) The pressure at the time the in-tank tube breaks or comes apart from test pipes, i.e., the breakage pressure, is greater than or equal to 2.8MPa, when the in-tank tube, after immersion in testing fluid [Fuel C: Methanol = 85:15 (based on volume)] for 168 hours at 80 degrees C, is then filled with silicon oil as a pressurizing medium, and a pressure resistance test is carried out at room temperature with both ends of the in-tank tube blocked with the test pipes, at a pressurization speed of 1.0MPa/min.
