Fuel meter mounting for an engine

Claim 2

A fuel meter mounting assembly, for the temporary installation of a fuel meter in the fuel supply system of an engine having pump means for supplying fuel under pressure to the engine and having support means interposed between the pump means and the engine to receive a removable fuel filter, said support means having a filter receiving surface against which said filter may be disposed and having attachment means for holding said filter against said surface and further having passages extending to said surface through which fuel is transmitted to said filter and received therefrom and having sealing means for said passages between said surface and said filter, comprising; a connection block fittable against said surface of said support means upon removal of said fuel filter and being engagable by said attachment means and including passage means communicating with said passages of said support means through said sealing means, and conduit means interconnecting said connection block and the fuel meter to provide a fuel measuring bypass circuit through the fuel meter and back to the engine.

Claim 3

The fuel meter mounting assembly of claim 1 including auxiliary adapter means connected to said conduit means between said connector member and the fuel meter and providing a mounting for receiving said fuel filter as an element of said bypass circuit.

Claim 4

A fuel meter mounting assembly, for the temporary installation of a fuel meter in the fuel injection system of an internal combustion engine having a fuel injection pump, transfer pump means for supplying fuel under pressure to the fuel injection pump, and filter support means between the transfer pump means and the fuel injection pump providing a plurality of pairs of openings against which a corresponding number of removable fuel filters may be disposed to filter fuel passing between said transfer pump means and said injection pump comprising; a connector block mounted on said support means in the place of one of said fuel filters and including passage means communicating with a pair of said openings, a plurality of fuel transfer conduits interconnecting said connector block passages and the fuel meter to provide a fuel measuring bypass circuit from the connector block through the fuel meter and back to the connector block, and an auxiliary adapter block connected to said fuel transfer conduits between said connector block and the fuel meter and connecting one of said fuel filters into said bypass circuit.

Claim 5

A fuel meter mounting assembly, for the temporary installation of a fuel meter in the fuel injection system of an internal combustion engine having a fuel injection pump, transfer pump means for supplying fuel under pressure to the fuel injection pump, and filter support means between the transfer pump means and the fuel injection pump providing a plurality of pairs of openings against which a corresponding number of removable fuel filters may be disposed to filter fuel passing between said transfer pump means and said injection pump comprising; a connector block mounted on said support means in the place of one of said fuel filters and including passage means communicating with a pair of said openings, a plurality of fuel transfer conduits interconnecting said connector block passages and the fuel meter to provide a fuel measuring bypass circuit from the connector block through the fuel meter and back to the connector block, and an auxiliary adapter block connected to said fuel transfer conduits between said connector block and the fuel meter and connecting one of said fuel filters into said bypass circuit.

Claim 6

The fuel meter mounting assembly of claim 3 in which said fuel meter has fuel inlet and outlet ports; and said fuel transfer conduits include a fuel line extended between said connector block and said inlet port of the fuel meter by way of said auxiliary adapter block for directing fuel through said filter thereon, and a fuel line interconnecting said outlet port of the fuel meter with said connector block.

Claim 7

In combination with an engine having a fuel flow passage defined in part by a fuel filter support with a surface against which a fuel filter may be disposed, wherein said surface has a pair of openings for transmitting said fuel flow to said filter and for receiving filtered fuel therefrom, means for measuring fuel consumption of said engine comprising; a flow meter having inlet and outlet ports, a connEctor block secured against said surface of said fuel filter support in place of a fuel filter and having a pair of passages each communicating with a separate one of said openings of said surface, an auxiliary block having a filter receiving surface similar to said surface of said support including a second pair of openings for transmitting fuel to a filter and for receiving fuel therefrom; a first conduit connecting one passage of said connector block with one opening of said auxiliary block, a second conduit connecting the other opening of said auxiliary block with said inlet port of said meter, a third conduit connecting said outlet of said meter with the other passage of said connector block, and a fuel filter disposed against said surface of said auxiliary block and communicated with said openings thereof.

Claim 8

In combination with an engine having a fuel flow passage defined in part by a fuel filter support with a surface against which a fuel filter may be disposed, wherein said surface has a pair of openings for transmitting said fuel flow to said filter and for receiving filtered fuel therefrom, means for measuring fuel consumption of said engine comprising; a flow meter having inlet and outlet ports, a connEctor block secured against said surface of said fuel filter support in place of a fuel filter and having a pair of passages each communicating with a separate one of said openings of said surface, an auxiliary block having a filter receiving surface similar to said surface of said support including a second pair of openings for transmitting fuel to a filter and for receiving fuel therefrom; a first conduit connecting one passage of said connector block with one opening of said auxiliary block, a second conduit connecting the other opening of said auxiliary block with said inlet port of said meter, a third conduit connecting said outlet of said meter with the other passage of said connector block, and a fuel filter disposed against said surface of said auxiliary block and communicated with said openings thereof.

Claim 9

The combination defined in claim 5 wherein said fuel filter support has threaded means at said surface thereof for screwing a filter thereto, wherein said connector block is secured against said surface by said threaded means and further comprising second similar threaded means for securing said filter against said similar surface of said auxiliary surface.
