Definitions

  • This invention relates to the injection of fuel into the working cylinders of internal combustion. engines by means of a high pressure air compressor, the air directly acting upon and opening the fuel supply valve which permits the fuel fromthe supply which is stored on the front side of the valve to pass to the engine.
  • he invention consists in. an improved arrangement of the fuel supply valve according to which the valve is placed in the cylinder head and at a certain distance from the fuel injector inlet, the said valve being adapted to close and open the supply channel which is common. to the compressed air and the fuel, in such a manner that the mixture does not pass through and around the valve.
  • the accompanying drawing illustrates one example of the invention, in which the compressed air is supplied by means of a twosta e high pressure air compressor.
  • Fig. 2 is a similar view, the compressor piston being shown in its highest position. he compressor is driven 1n any known manner from the engine driving shaft by means which are not shown or. from a counter shaft which is separately driven from the above named main shaft.
  • the compressor is shown in the drawing as a two-stage compressor and is provided with a differential piston, an intermediate pres sure chamber and a separate suction valve for atmospheric air in the high pressure cylinder.
  • valve 1 indicates the low pressure piston and 2 the low pressure cylinder provided with the suction inlet 3 .and the outlet 4.
  • Through the valve 6 passes the air compressedunder low pressure, to theintermedmte receiving chamber 5, from whence it passes to the high pressure cylinder 8 above the piston 7 at the end of the stroke.
  • 9 is a valve acted upon by a spring, through which valve at- Specification of Letters Patent.
  • mospheric air is supplied to the high pressure compressor at the down-stroke of the piston, the compressor thereby receiving an additional supply of air.
  • the compressed'air charge passes along the duct into which is led the f through which fuel is supplied under sulficient pressure to be forced into the conduit or duct 10 against the pressure of the compressed air therein, so that the latter part of such duct 10 receives the mixture of fuel and air.
  • 13. is the injector channel by which the mixture passes into the Working cylinder, and communication between the duct uel supply duct 16,
  • valve 10 and the channel 13 is controlled by the fuel inlet valve'l2.
  • the valve member is hollow to accommodate a valve spring 14.- and by means of an. adjusting screw 15 the valve spring is given such a tension that it will open on the power stroke, of 'the compressor at any pressure, whereby the fuel mixture will be injected at the right moment to precisely regulate the time of combustion.
  • the valve 12 is arranged in the cylinder head and spaced a short distance from the injector inlet so that it will not be in the cylinder and its reciprocating motion hindered by un-burned substances which may be thrown down by the mixture of air and fuel.
  • an air compressor having an outlet conduit, a valve seating and housing formed co-axially with said conduit, a cylindrical valve mounted as a sliding fit in such housin and normally closing said conduit, the hea of said valve bein directly operated upon by compressed airor opening said conduit, a fuel supply inlet communicating with said conduit between the air compressor and valve housing and an outlet for air and fuel normally and does not go around or fuel are deflected to a mlnimum extent and desired degree of pass exteriorly of the valve body and valve seating.
  • an alr compressor having an outlet conduit, a valve seating and housing formed co-axially with said conduit, a cylindrical valve mounted as a sliding fit in such housing and normally valve housing closing said conduit, the head of said valve being directly operated upon by compressed air r opening said conduit, a spring for normally holding said valve closed, means for varying the tension of said spring, a fuel supply inlet communicating with said conduit between the air compressor, and and an outlet for airand fuel normally closed by such valve such that the air and fuel are deflected to a minimum extent and pass exteriorly of the valve body 1 and valve seating.
  • an air compressor having an outlet conduit, a valve seating and housing formed co-axially with said conduit, a cylindrical valve mounted as a sliding fit in such housing, and normally closing said conduit, the head of said valve being directly operated upon by compressed air for opening said conduit, a fuel supply inlet communicating with the said conduit between the air compressor and valve housin adjustable yielding means for normally ho ding the valve in closed position, and an outlet for air and fuel normally closed by said valve, such that the air and fuel are deflected to a minimum extent and pass exteriorly of the valve body and valve seating.
