1966 w. s. SCHOEPPACH 3,232,497
LIQUID FUEL SUPPLY SYSTEM Filed Jan. 17, 1964 INVENTOR.
A 7' TORNE y gar/4 United States Patent 3,232,497 LIQUID FUEL SUPFLY SYSTEM Wayne S. Schoeppaeh, Mount Morris, Mich assignor to General Motors Corporation, Detroit, Mich, a corporation of Deiaware Filed Jan. 17, 1964, Ser. No. 338,516 3 Claims. (Eli. 222-380) This invention relates to a fuel system and more particularly to a liquid fuel system including a supply tank adapted to serve an internal combustion engine spaced from the tank.
A difficulty has been tive vehicles In that These and other important features of the invention will now be described in detail in the specification and then pointed out more particularly in the appended claims.
In the drawings:
FIGURE 1 is a partial view of components making up a fuel system in which the present invention is embodied; and
FIGURE 2 is an enlarged and sectional view of a portion of a fuel pump illustrated in FIGURE 1.
The drawings show a fuel tank containing gasoline 12 and having an opening 14 in its top through which is suspended a gasoline pump 16. This pump advantageously may be of the type described in the United States Patent 2,968,248, granted January 17, 1961, in the name of Robert L. Carter. This pump has a screened inlet such as indicated at 18 which is arranged closely to approach the bottom of the tank 10. It will be appreciated, however, that other forms of the pump could be utilized in practicing the present invention.
The pump 16 has a botom portion 20 and an intermediate portion 22 between which is interposed a sealing gasket 24. The portions 29 and 22 are not shown in detail as their details do not form a part of the present invention but it sufiices herein to state that the two portions 20 and 22 cooperate in defining a pump discharge conduit 26 leading to a pump outlet connection generally indicated at 28.
The outlet conection 28 is formed with two ports 30 and 32. These ports are axially aligned although not necessarily so. The port 30 is facing the interior municates with a discharge line 36 leading to a carburetor 38 serving an internal combustion engine.
The port 32 is formed in a circular disk 40 which is welded as at 42 to the cylindrical wall of a cylinder or chamber 44 formed in the pump portion 20. Slidable in 34 serving as a valve seat. a coil Si) is positioned between the disk 40 and the piston valve 4-8 constantly urging position against the lip 34.
In operation, the through the discharge because of the but With the use siphoning action heretofore referred to of the present construction the terminaand the spring 50 then becomes effective 30 and prevents any siphoning action.
I claim:
1. A liquid fuel supply system for an engine, said system comprising a tank, a pump having an inlet connected with the interior of said tank and an outlet connection, said outlet connection having two ports, a discharge line to close the port pump is adapted said spring means References Cited by the Examiner UNITED STATES PATENTS 2,618,290 11/1952 Van Vliet 6/1962 Hoelle 222-333 X FOREIGN PATENTS 9,012 9/1927 Australia.
