LIQUID FUEL CATCHER

摘要

A liquid fuel catcher has a case which defines a plurality of chambers formed as depressions in a passage so that a liquid fuel is accumulated. The case has a communicating portion which communicates the chambers in series at upper portions thereof. The case has openings at each bottom portions of the chambers. The case has a return passage which returns the liquid fuel accumulated in the chambers to a fuel tank. The liquid fuel catcher has a return valve. The return valve closes the return passage, when the liquid fuel level in the fuel tank exceeds a predetermined level. The return valve opens the return passage, when the liquid fuel level in the fuel tank is less than a predetermined level. The fuel returns to the fuel tank from the chambers through the return valve.

主权项

1. A liquid fuel catcher, which allows fuel vapor to pass through and catches a liquid fuel, the liquid fuel catcher comprising:
a case which defines a passage through which fluid containing fuel vapor and the liquid fuel flows, wherein the case defines: a plurality of chambers defined as depressions on the passage so that the liquid fuel accumulates; a communicating portion which communicates the chambers in series at upper portions thereof; and a return passage which opens at each of bottom portions of the plurality of chambers and allows the liquid fuel accumulated in the chambers to return to a fuel tank, and wherein the liquid fuel catcher further comprises: a return valve which closes the return passage when a liquid fuel level in the fuel tank is higher than a predetermined level, and opens the return passage when a liquid fuel level in the fuel tank is lower than a predetermined level to return the liquid fuel to the fuel tank from the plurality of chambers.
