Definitions

  • the device comprises an inlet valve, whose valve rod is slidably mounted in the bore of a valve guide and whose valve head controls the admission of a first fluid into the combustion chamber, with a longitudinal pipe arranged in the valve rod and a passage being an extension of this pipe arranged on the internal face of the valve head.
  • the feed tube for the second fluid opens into the bore of the valve rod through a first aperture and a second aperture is provided through the valve rod interconnecting said bore with the longitudinal pipe, at such a location as to register with the first aperture exclusively when the valve is open, means being provided for preventing any rotation of the valve around the axis of the valve rod.
  • the present invention relates to a device for the almost simultaneous admission of two different fluids into the combustion chamber of a combustion engine.
  • the device according to the present invention is of special interest to carry into effect the process according to US. Patent 3,087,480 and in the following description particular reference will be made to this type of use, although many other useful applications of the present device can be conceived by any one skilled in the art.
  • the process according to the above numbered patent consists in feeding external combustion engines by means of two distinct jets of combustible mixtures of diiferent richness, so that the richer mixture jet is directed toward the spark-plug, thus enabling sufficient richness to be maintained around the spark-plug for ignition of a mixture which is, in the aggregate, poor.
  • a device for utilizing this process can comprise an inlet tube for the richer mixture, placed inside the air or poor mixture intake tube, the said inlet tube being directed toward the spark-plug.
  • the device when applied to the above-mentioned process, enables these drawbacks to be remedied since, when closed, it cuts off supplies to the rich mixture intake tube.
  • a device for admitting two fluids of different characteristics into a combustion chamber of a controlled ignition engine during the introduction phase thereof comprises in combination with said chamber a first fluid feed tube running into the head thereof through an aperture, a valve having a head intermittently closing said aperture and a valve rod, a valve guide integral and said chamber head, said valve'rod being slidably mounted into said valve guide.
  • the device according to the present invention further comprises in combination with the above mentioned elements a first pipe, arranged in said valve rod in a direction substantially parallel to its axis, a second pipe being an extension of said first pipe and forming a knee therewith arranged in said valve head on the internal face thereof, so as to be entirely housed in said first feed tube when the valve is closed.
  • a second fluid feed tube having a first opening into said valve guide, a second opening interconnecting said first .pipe with said valve guide, said second opening being so placed as to register with said first opening when the valve is open, thereby providing intermittent connection of said first pipe with said second feed tube when the valve is open, said registering being interrupted when the valve is closed, so as to cut off said connection.
  • FIG. 1 in a section following a plane passing through the longitudinal axis of the valve, represents one embodiment of the device according to the invention in which the pipe fittted into the valve rod is an axial internal pipe.
  • FIG. 2 shows a longitudinal section of the valve with its internal pipe.
  • FIGS. 3 and 4 show slightly different modifications of the pipe fitted in the valve head.
  • a valve comprises at the inside a first pipe 2 coaxial to the axis of the valve rod which slides in the internal cylinder bore of a valve-guide 18, said first pipe 2 extending into the valve-head by a second pipe 3 forming a knee with the first pipe 2, and, according to this embodiment, being perpendicular thereto.
  • the second pipe 3 is placed in the valve head in such a way that, when the latter is raised, the second pipe 3 is directed toward the electrodes 4 of the spark-plug 5.
  • valve direction locking system elfected, for example, by using a flat part 6 fitted to the valve rod, with a fixed part such as a lug 7 the flat end of which rests on the fiat part 6.
  • Valve rotation can also be prevented, for example, by means of a pin running through the valve rod and guided into a. groove provided in the guide 18 parallel to the rod axis.
  • Valve movement is thus limited to longitudinal movements parallel to the valves axis.
  • the first pipe 2 inside the valve rod connects with the internal cylinder bore of the guide of the said rod by means of an opening 8, and the input portion 9 of the rich mixture feed tube also runs into the said internal cylinder bore of the guide by opening 10.
  • Opening 8 and 10 are made in such a way that there is connection between them when the valve is up and no connection when it is closed.
  • valve head In the closed position, the valve head is brought on the valve seat 12, set in the engine head 13 by the valve spring 14.
  • Valve opening can be operated by any standard device.
  • opening the valve brings about simultaneously the admission into the cylinder of the rich mixture by route 9-1082-3, and of the poor mixture by the intake tube 11.
  • complete closing of the valve brings about the locking of both rich and poor mixture intakes, without there being any connection between them.
  • the diameter of the rich mixture inlet tube is necessarily limited by construction to a mixture value less than the diameter of the valve rod.
  • the rich mixture may become very rich indeed.
  • the mixture In cases of operation for which such richness of the mixture is excessive, the mixture should be diluted as it enters the combustion chamber. This dilution can be easily obtained by using the fittings shown in FIGS. 3 and 4.
  • valve shown in FIG. 3 dilfers from that illustrated in FIG. 2 by an aperture 15 on the lateral surface of the second pipe 3.
  • This aperture allows dilution of the rich mixture by the poor mixture at the moment of intake, as there is induction of the poor mixture through the said lateral aperture.
  • a device for admitting two fluids of dilferent characteristics into a combustion chamber of a controlled ignition engine during the induction phase thereof comprising a first fluid feed tube running into the head of said chamber through an aperture, an inlet valve having a head for intermittently closing said aperture and a valve rod, a valve guide integral with said chamber head and having an internal bore; said valve rod being slidably mounted in said bore, a longitudinal pipe arranged in said valve rod in a direction substantially parallel to its axis, and having an opening in said bore, a passage being an extension of said pipe and arranged in said valve head on the internal face thereof so as to be entirely housed in said first fluid feed tube when the valve is closed, a second fluid feed tube having an opening into said internal bore, so placed as to register with the opening of said longitudinal pipe in said bore when the valve is open, thereby providing for intermittent connection of said longitudinal pipe with said second fluid feed tube, said registering being interrupted when the valve is closed, thereby interrupting said connection and means provided for preventing any rotation of the valve around the axi
  • said means for preventing any rotation of the valve around the axis of said valve rod comprising a flat part fitted on the valve rod and a lug which is integral with the valve guide.
  • a device in which said means comprise a pin running through the valve rod and being guided in a groove made in the valve guide parallel to the axis thereof.
