Abstract

The first seal seat is disposed in a first passage of a case. The first float valve body is disposed in the case and closes the first seal seat in response to the liquid level of the fuel. The second seal seat is disposed vertically above the first seal seat, in a second passage of the case. The second valve body is disposed on one side of the second seal seat communicating to the outside of the second passage, with being resiliently urged upwards from below. The second float is disposed in the case and regulates an upper end position of the second valve body to open the second valve seat in response to movement of the liquid level of fuel at least until the liquid level is higher than the liquid level at which the first float valve body closes the first seal seat.
