摘要： A valve apparatus is small, and regulates a fuel amount by restricting a lift amount of a valve. A columnar portion is formed on a pump body. The columnar portion is inserted into a check valve and a washer formed with a protruding portion which protrudes outward from a flange portion, and the check valve and washer are attached or fixed to the pump body by subjecting a tip end of the columnar portion to thermal caulking or the like. An outer diameter of the protruding portion is set to be relatively smaller than an outer diameter of the flange portion such that when the check valve is sandwiched between the protruding portion and pump body, the check valve contacts an outer peripheral edge of the flange portion when the check valve opens. As a result, a lift amount of the valve can be restricted, and a flow rate of fuel passing through a passage can be maintained at a constant level.

摘要： The present invention provides a valve apparatus which is small and reasonably priced, and with which a fuel amount can be regulated by restricting the lift amount of a valve. A columnar portion 60 is formed in a body 16, the columnar portion 60 is inserted into a valve 44, 46 and a washer 62 formed with a protruding portion 72 which protrudes outward from a flange portion 64, and the check valve 44, 46 and washer 62 are attached or fixed to the pump body 16 by subjecting the tip end of the columnar portion 60 to thermal caulking or the like. The outer diameter of the protruding portion 72 is set to be relatively smaller than the outer diameter of the flange portion 64 such that when the check valve 44, 46 is sandwiched between the protruding portion 72 and pump body 16, the check valve 44, 46 contacts an outer peripheral edge 70 of the flange portion 64 when the check valve 44, 46 opens. As a result, the lift amount of the valve 44, 46 can be restricted, and the flow rate of the fuel passing through a passage 40, 42 can be maintained at a constant level.
