Definitions

  • the present invention relates to a Diesel pile driver for impact atomization.
  • the invention is based on a pile driver for impact atomization according to which a piston at its impact atomizes the fuel conveyed by a measuring pump to the impact surface of the impact element.
  • FIG. 1 illustrates a longitudinal section taken along the line I l of FIG. 2, said section being taken through the lower portion of the Diesel pile driver, and showing a certain phase of the working cycle of the Diesel pile driver.
  • FIG. 2 is a cross section taken along the line [I I] of FIG. 1.
  • the present invention starts with the surprising findingthat the fuel in not yet atmoizedrcondition is distributed over a plane surface within the short available time, to such an extent in a moistening manner over the entire plane impact surface that also in such an instance the impact atomization can be realized by means of piston and impact member with plane end surfaces.
  • the fuel After the fuel has previously been atomized by the plane surfaces 13.1 and 14.1 impacting upon each other, the fuel is radially centrifuged into said annular chamber, which fuel has been applied in the form of a moistening film to the impact surface 13.1. In view'of the pressure prevailing in this compression chamber, the atomized fuel will be able to combust. In view of the explosion-like increase in pressure the piston 14 is thrown up again.
  • the outside of cylinder 12 has associated therewith a metering device 18 for metering out the quantity of fuel required for each individual combustion operation.
  • a fuel measuring pump associated with said measuring device 18 is so designed and arranged that the fuel in the form of a not yet atomized jet will be conveyed into the cylinder at an instant at which the inner space of the cylinder at a corresponding position of the piston 14 will by opening a nonillustrated air admission and combustion gas exhaust offer practically no or only slight over pressure.
  • the admixing device has a double lever 16 having its arm 16.1 extending into the inner chamber of the cylinder 12, and with all these parts is arranged below the piston 14 occupying its upward position.
  • the double lever 16 is pivotally mounted on the cylinder and will have its other arm 16.2 engaging the upper end 17 of the nonillustrated piston pertaining to the metering pump arranged at the circumference of cylinder 12.
  • the upwardly moving piston 14 has, by means of its circumference, moved the arm 16.1 of this double lever 16 out of the cylinder chamber and has pivoted the entire double lever 16.
  • the other arm 16.2 has, by means of the piston end 17, pressed the piston of the metering pump downwardly. Consequently, the fuel is in a predetermined quantity conveyed in the form of a closed jet 20 through a passage 19 onto the impact curface 13.1 of the impact member 13. Jet 20 will at an incline, at a pointA impact upon said surface 13.1.
  • the impact area A is offset from the center of the surface toward the metering pump, and the jet 20 is so inclined that the impacting fuelwill on the plane impact surface 13.1 have imposed thereupon a component of movement by means of which from said pointA the fuel jet in the form of an expanding thin film 15 will be distributed toward the circumference of the surface 13.1.With such distribution, the impact surfaces 13.1 and 14.1 impacting uponeach other will bring about aparticularly fineatomi'zation of the fuel. 1
  • a Diesel pile driver exclusively for operation with the principle of impact atomization of fuel supplied in unatomized condition at low pressure, which includes: cylinder means, an impact member guided in said cylinder means, and having an impact area, a piston having an impact surface and being reciprocable in said cylinder means and also being operable to have its impact surface impact upon said impact area of said impact member having a face surface upon which unatomized fuel is applied by pump dosage for resulting in atomizing fuel conveyed to the impact area of said impact member, said impact surface of said piston and said impact area of said impact member respectively forming entirely flat plane surfaces substantially parallel to each other.
  • a pile driver which includes: a metering pump associated with said cylinder means, and control lever means operable by said piston for controlling said pump, said cylinder means being provided with conduit means communicating with said pump and having its axis inclined toward-the axis of said cylinder means so that the point of intersection of the axis of said conduit means with said impact area will in the innermost position of said impact member in said cylinder means be offset in a direction radially outwardly of the axis of said impact member.
