  • Patent number: 5832950
    Abstract: In a fuel interruption device for a fuel tank, a main valve is prevented from opening as a result of the action of an auxiliary valve during closure of the main valve; and more specifically, an auxiliary valve which is caused to move up and down by a float and a main valve which moves up and down in linkage with the up and down movement of the auxiliary valve are accommodated inside a casing which allows the inflow and outflow of liquid fuel and is provided at the end of a passage which connects the fuel tank and canister; a linking projection is provided on one of the valves, that is, either the auxiliary valve or the main valve, so that the main valve moves in linkage with the auxiliary valve in an action that is either advanced or retarded within a predetermined range, and a projection regulating groove into which the linking projection is inserted so that the projection can change its position within the range is formed in the other valve; and auxiliary valve seat and main valve seat open independently in

  • Patent number: 5724947
    Abstract: In a fuel pump unit, to solve (1) the problem of a valve of a reserver opening unnecessarily due to vibrations from outside or the like and (2) the problem of it not being possible to supply to an engine remaining fuel having fallen to below a minimum intake level, a main tank valve and a reserve valve respectively close from above a main fuel inlet connecting with a fuel intake passage of the fuel pump unit and an auxiliary fuel inlet connecting with the fuel intake passage and a rocking member having a force point pivotally attached to the main tank valve and having the action of pushing up the reserve valve with an action point and thereby opening the auxiliary fuel inlet when the main tank valve closes the main fuel inlet is provided and a sub-float for descending and pushing down the reserve valve from above when excess fuel in the reserver runs out is disposed in the reserver.
