Definitions

  • This invention relates to apparatus for feeding fuel to an internal combustion marine engine.
  • An aim of the invention is to provide a reasonably inexpensive, yet safe and practical installation for feeding fuel to a marine engine, and for controlling the fuel feed.
  • apparatus for feeding fuel to marine engines which comprises a generally annular chamber having on its inner wall a series of peripherally-spaced orifices, a conduit connected to the annular chamber, a branch pipe secured to the conduit, and a helical rotary scroll valve member located in the conduit to obturate an adjustable proportion of the branch pipe opening dependent upon the rotational position of the scroll valve member, and a radial lever connected to the valve member.
  • apparatus for feeding fuel to a marine engine including a fuel feed pipe leading from a fuel storage container to a fuel intake of a carburettor, the pipe having one portion which is outside the hull of the vessel and a further portion which is inside the hull of the vessel, the apparatus also including a tubular gas or liquid-tight casing which surrounds the whole length of the said further portion of the feed pipe and extends to a fitting on the carburettor, the tubular casing at its end remote from the fitting being open to atmosphere.
  • the fitting is preferably constituted by the'said branch pipe, the latter being directly connected to the said fuel feed pipe.
  • the radial lever may be operated in response to movement of the butterfly valve in the carburettor.
  • a drain pipe is preferably located between an inlet flange associated with the carburettor and the hull of the vessel above the waterline.
  • the invention may be applied to a horizontal air intake flow type carburettor, or to a downdraught carburettor.
  • the invention may be applied whether the fuel is liquid or gas; for example the fuel could be petrol, any liquid hydrocarbon fuel, or low pressure hydrocarbon gas.
  • the tubular casing may be at least partly of flexible material.
  • a marine vessel has a deck 10, a transom 12, and an internal combustion engine 14. The remainder of the vessel is conventional and so is not shown.
  • a container 16 with an open top has a drain hole 18 connected directly through the transom 12 to the outside.
  • the illustrated vessel is intended to be propelled by LPG (liquefield petroleum gas) which is stored at high pressure and gasifies upon release of pressure.
  • LPG liquid petroleum gas
  • In the container 16 are a cylinder 20 of compressed LPG in liquid form, a fuel lock 22, and a liquid-to-gas converter 24. These are-known items of equipment and therefore will not be described in detail.
  • a gas feed pipe generally indicated at 26 extends from the converter 24 to a branch pipe 50.
  • a first portion 26A of the pipe 26 passes through a wall of the container 16 and through the transom 12.
  • a second portion 268 is outside the vessel.
  • a third portion 26C passes through a hole 32 in the transom 12 and within a and through a tubular casing 34.
  • the engine 14 is conventional and has a carburettor 40 of known design fixed thereto.
  • An annular chamber 52 is secured to the carburettor 40 and has a conduit 54 projecting therefrom.
  • This conduit serves as a valve body for a helical rotary scroll valve member 56 which obturates the whole of the orifice formed by the branch pipe 50 in the conduit 54 when in its closed position, and which, when rotated, progressively exposes more of this opening so allowing LPG to flow into the conduit 54 and thence into the hollow annular chamber 52.
  • the latter is secured in a gas-tight manner to the carburettor 40 and the feed pipe 26D is secured in a gas-tight manner to the branch pipe 50.
  • the annular chamber has a series of peripherally spaced orifices 60, Figure 2, through which the fuel gas passes on its' way to a combustion chamber of the engine 14. It may be bolted to the carburettor using bolt holes 61.
  • the effective size of each of the orifices 60 is adjustable by means of an arcuate slide plate 160 located behind the wall 166 containing the orifices.
  • the slide plate 160 has a similar number of correspondingly sized and spaced orifices which can be brought into and out of strict register with the orifices 160 by sliding the slide plate.
  • the slide plate is secured in any predetermined position by a screw 162 in the slide plate which extends through a slot 164 in the wall 166.
  • One end of the casing 34 is closed in a gas-tight manner by a flange 62, which has a small cup-shaped extension 64.
  • the purpose of this cup-shaped extension is to collect any LPG which may have leaked within the casing 34 and conduct it away via a pipe 66 to the exterior of the vessel.
  • the valve member 56 has a boss on its outer end to which is securely fixed a radial levet 70. This has a hole 72 at its outer radial end to facilitate connection of a link or control cable (not shown) by which rotation of the lever about the axis of the scroll valve member 56, and hence rotation of the scroll valve member on be caused.
  • the link or control cable referred to is attached to a suitable control mechanism so that when the carburettor butterfly valve 74 is opened the scroll valve member is rotated in an opening direction, and vice versa.
  • the tubular casing 34 which may be at least partly of a flexible material, for example a rubber or plastics bellows, is connected between the flange 62 and a flange 52 on the inner side of the transom and surrounding the hole 32.
  • the connections are made at each end in such a way that LPG cannot leak therethrough.
  • the flexible nature of the tubular casing 34 assists in ensuring that the integrity of these gas-tight connections is maintained even though there is relative vibration between the flange 62 (which vibrates with the engine) and the transom 12 of the vessel.
  • a marine vessel has a deck 210, a transom 212, and an internal combustion engine 214. The remainder of the vessel is conventional and so is not shown.
  • a gas feed pipe generally indicated at 226 extends from the converter 24 to an adaptor block 230.
  • a first portion 226A of the pipe 226 passes through a wall of the container 216 and through- the transom 212..
  • a second portion 226B is outside the vessel.
  • a third portion 226C passes through a hole 232 in the transom 212 and within and through a tubular casing 234.
  • a fourth portion 226D of the pipe 226 passes through a flame trap 236 and the pipe 226 terminates at a suitable bore or fitting 230A (Fig. 6) in the adaptor block 230.
  • the engine 214 is conventional and has a carburettor 240 of known design fixed thereto.
  • the adaptor block 230 is securely fixed, e.g. by bolts and suitable sealing washers, to the carburettor 240. The fixing is done in a gas-tight manner.
  • the flame trap 236, which may also serve as an air cleaner, and which may consist of a casing or chamber having wire wool packing therein, is fixed in a gas-tight manner, to the adaptor block 230 in such a way that its interior is in communication with a central hole in the adaptor block, and, via said hole, with an air entry port of the carburettor 240.
  • a flange member 250 is secured also in a gas-tight manner to another wall of the flame trap 236.
  • the tubular casing 234 which may be at least partly of a flexible material, for example a rubber or plastics bellows, is connected between the flange member 250 and a flange 252 on the inner side of the transom and surrounding the hole 232.
  • the connections are made at each end in such a way that LPG cannot leak therethrough.
  • the flexible nature of the tubular casing 234 assists in ensuring that the integrity of these gas-tight connections is maintained even though there is relative vibration between the flange member (which vibrates with the engine) and the transom of the vessel.
  • the adaptor block 230 has a central hole 230f, Figure 6, and this serves as the air entry pathway for air sucked into the carburettor from outside the engine via holes in the flame trap 236.
  • a rigid pipe 254 connects the fitting 230C with a fuel inlet port of the carburettor 240.
  • the flange 252 is fixed in a gas-tight manner to the transom 212 and the casing 234.
  • the adaptor block 230 has flanges 230F and holes 230G whereby it can be bolted to the carburettor 240.
  • the block 230 may be made of aluminium alloy.
  • the flange 252 and the flange member 250 could of course be replaced by other suitable fittings.
  • the separate adaptor block 230 and rigid pipe 254 are dispensed with, and the carburettor comprises a block containing its working parts and already-provided with bores providing the passageway from the end of the fuel feed pipe to the fuel entry port of the carburettor.
  • a downdraught carburettor 100 has an air intake at its top surface and carries thereon a flame trap 102, fixed for example by bolts 104.
  • the air control butterfly is denoted by 105.
  • a fuel inlet pipe 112 leads to a fuel control valve 108 and fuel flows therefrom into the body of the carburettor via a pipe 109.
  • the engine inlet manifold is shown at 110.
  • the fuel feed pipe 112 is secured in a liquid- and gas-tight manner to the fuel control valve 108, using a flange 114 similar in essential function to the flange shown in Figure 3.
  • a tubular casing 122 is connected in a liquid-and gas-tight manner to the flange 114.
  • the tubular casing 122 extends from the flange 114 to the transom (not shown in Fig. 9) of the vessel, in a similar way to the tubular casing 34 of Figure 1.
  • the flange 114 ( Figure 9) comprises a flat plate 130 having a cylindrical sleeve 132 extending therefrom. The end of the tubular casing 122 fits tightly around the sleeve 132.
  • the plate 130 has a generally central hole 134 through which passes the pipe 112 which is thereupon directly connected and sealed to the valve 108.
  • the flange 114 also has a smaller, offset hole 136 therein which extends to an aperture surrounded by a short external cylindrical sleeve 138.
  • a drain pipe 140 is sealed to this sleeve 138 and extends, for example laterally of the vessel at a point above the waterline.
  • Figure 10 depicts a vessel including apparatus according to the invention which is slightly modified compared to Figure 1 and 3.
  • the container 16 has a drain hole 300 leading to an exit hole 302 in the transom 12.
  • the tubular casing 34 has a bend therein, and terminates in a flange 50 whose construction can readily be seen from Figures lla and llb.
  • a drain pipe 304 leads from the flange 50 to the exterior of the hull of the vessel, above the waterline. With this arrangement, any leakage of fuel whether gas or liquid is conducted to the exterior either via the exit hole 302 or the drain pipe 304, and cannot enter the bilges of the vessel.
  • Figure 12 illustrates a vessel incorporating the example of the invention shown in Figure 10 seen looking forward.
  • the vessel has a hull 10, a transom 12, a rudder 202, rudder pintles 204, an engine 14 (supported on structural members 14a), and a carburettor 40.
  • a tubular casing 34 extends from a container 16 to a flange 50.
  • the drain pipe 304 extends from the flange 50, laterally of the vessel, to an outlet 142 located above the waterline.
