燃料タンク用バルブ
Document Type and Number:
Japanese Patent JP4394508
Kind Code:
B2
Abstract:
A valve for a fuel tank includes an upper space or chamber communicating with a ventilation channel; a lower chamber disposed inside a fuel tank; a communicating part for communicating the upper space with the lower chamber; and a float body disposed inside the lower chamber for floating to block the communicating part from the lower chamber when fuel flows into the lower chamber. A space between an inner surface of the lower chamber and an outer surface of the float body becomes a flow channel for gas when the float body is in a lower position. A distance between the outer surface of the float body and the inner surface of the lower chamber is not uniform in a circumferential direction of the float body. A portion having a large distance functions as a main flow channel for gas.
