Abstract:
An evaporated fuel treatment device executes a pressure reducing control while monitoring inner pressure of a fuel tank, so that when the inner pressure of the fuel tank exceeds a predetermined value prior to fueling to the fuel tank, pressure reduction progresses within a range that the flow rate of a vapor passage does not exceed the boundary flow rate where the vapor passage is closed by a valve element of an ORVR valve, and also a valve opening speed of the closing valve is made higher as the inner pressure of the fuel tank becomes lower.

Claim (Index 1):
An evaporated fuel treatment device comprising:\n a canister which sorbs evaporated fuel generated in a fuel tank of a vehicle; a vapor passage which connects between the canister and the fuel tank; a closing valve which is provided to the vapor passage and allowed to change an opening degree so as to control a flow rate of the evaporated fuel flowing in the vapor passage; a valve mechanism which opens and closes the vapor passage by using a displacement of a float type valve element depending on a fuel level of the fuel tank; and a control device which is a computer, and by executing a computer program, configured to execute a pressure reducing control where the closing valve is controlled so that an inner pressure of the fuel tank is reduced prior to fueling to the fuel tank, wherein the control device is configured to control the pressure reducing control with monitoring the inner pressure so that, in a case that the inner pressure exceeds a predetermined value prior to the fueling to the fuel tank, reduction of the inner pressure progresses within a range that a flow rate of the vapor passage does not exceed a boundary flow rate where the vapor passage is closed by the valve element of the valve mechanism, and a valve opening speed of the closing valve is made higher as the inner pressure becomes lower.
