Document Type and Number:
Japanese Patent JP3498846
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a liquid level detection valve for a fuel tank capable of surely carrying out a switching operation without causing malfunction by correctly detecting the liquid level of a fuel in the fuel tank.
SOLUTION: This valve is so composed that a floating body 50 provided with, at its upper end part, a valve head 60 having an upper end surface spherically formed is housed in a nearly cylindrical body 3, and the valve is closed by raising the floating body 50 in conjunction with the rise of the liquid level to abut the upper end face of the valve head 60 on a valve seat 14 formed on the inside surface of the upper wall of the body 3. The valve seat is composed by fixing the valve seat 14 formed with a ring-like elastic body to a valve seat mounting part formed on the upper part of the inside surface of the body, so that the rapid decrease of the space between the valve head 60 and the valve seat 14 is prevented.
