FUEL FILTER CLOGGING INHIBITION MECHANISM AND FUEL FILTER DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a fuel filter clogging inhibition mechanism that can inhibit a fuel filter from clogging during use under a low-temperature environment.SOLUTION: In the fuel filter clogging inhibition mechanism, a mixing part 23 connects a feed fuel passing part 21 to a return fuel passing part 22 when the temperature of feed fuel passing through a feed fuel passage is lower than a first preset temperature so as to control return fuel flowing through the return fuel passing part 22 to be mixed with the feed fuel passing through the feed fuel passing part 21.SELECTED DRAWING: Figure 3
