Definitions

  • the invention relates to a connecting rod-less double-piston internal combustion engine, with a crankshaft that engages with a cranked crank portion on the double piston.
  • a connecting rod-less double-piston internal combustion engine is already known from DE 35 18 303.
  • the linear movement of the double piston is transmitted to the crankshaft with the interposition of a sliding block which is guided transversely in the piston and into which a cranked crank section of the crankshaft engages.
  • the sliding block performs a linear back-and-forth movement, ie it is disadvantageously necessary to convert from a linear movement to a rotary movement.
  • the proposed kinematics are also not or not well suited for reverse power transmission and for use as a motor.
  • the object of the present invention is to provide a power transmission with reduced losses and reduced wear in a connecting rod-less internal combustion engine of the type mentioned at the outset.
  • a rotary element is rotatably mounted within the double piston, the axis of rotation of which runs parallel to that of the crankshaft and that the rotary element has a bearing opening arranged eccentrically to the central transverse axis of the double piston for the crank section of the crankshaft. Due to the rotating element rotatably mounted within the piston, the power transmission from the piston to the crankshaft takes place exclusively in a rotary manner. This enables an improved efficiency to be achieved.
  • This transmission mechanism requires neither parallel guides nor push rods, so that overall there is only very little effort and a small number of moving parts.
  • the rotary element is expediently designed as a disk and rotatably mounted in a longitudinal center plane of the double piston.
  • the crank section bears a gearwheel that is connected to it in a rotationally fixed manner and meshes with a ring gear that is arranged within the double piston in a rotationally fixed manner.
  • Power transmission from the crankshaft to the double piston is possible via such a transmission mechanism.
  • the piston can be set in motion during a starting process in which the crankshaft is driven. After the starting process and then the reverse direction of power transmission from the double piston on the crankshaft, this gear transmission has no function.
  • a preferred application of the internal combustion engine according to the invention provides that it is part of a portable pump for fire-fighting purposes as the drive.
  • the low weight and the small construction volume of the connecting rod-free internal combustion engine have a particularly advantageous effect, and the proposed internal drive transmission contributes to the high reliability and durability of the drive, as is required in such applications.
  • at least one cylinder part can be a compressor or a pump. This enables a compact motor-pump unit to be formed, the gear connection between the gearwheel that is non-rotatably connected to the crank section and the ring gear that is non-rotatably connected to the double piston is provided for the power transmission from the crankshaft to the double piston of the pump.
  • a connecting rod-less double-piston internal combustion engine 1 shown in FIG. 1 has a double piston running in a cylinder 2 3, whose outer end faces are facing combustion chambers 4 and 5, respectively.
  • the double piston 3 moves back and forth according to the double arrow Pf1 and is in its left dead center position in the illustration shown in FIG. 1.
  • a rotary element 6, preferably designed as a disk, is rotatably mounted within the double piston, the axis of rotation 7 of which runs parallel to the rotary axis of the crankshaft 8 (cf. FIG. 2).
  • the crankshaft engages with a cranked crank section 9 in a slide bearing opening 10 of the rotary element 6 which is arranged eccentrically to the central transverse axis of the double piston or to the axis of rotation 7.
  • the crank section 9 has a gear 11 which is connected to it in a rotationally fixed manner and which meshes with a ring gear 12 which is arranged within the double piston 3 in a rotationally fixed manner.
  • the drive transmission elements 11 and 12 are also required when used as a pump or compressor.
  • one or more of the cylinders could be part of a compressor or a pump, the pump and the drive motor having a common crankshaft.
  • Such arrangements are particularly suitable for mobile devices, for example also for portable fire pumps of the fire service.
  • the crankshaft can be connected particularly easily to the double piston or the rotary element 6 which is rotatably guided therein, the offsets 13 adjoining the crank section 9 being dimensioned such that the piston can be threaded onto the crankshaft.
  • the assembly is thus particularly simple to carry out and no further connecting or fastening elements are required in the transition region between the crank section 9 and the rotating element 6.
  • the gear 11 can also be mounted axially displaceably on the crank section 9 and connected to an engagement and disengagement device. It is therefore possible to run the pump or the compressor as required or to switch it off. It is expedient if a synchronizing device is provided between the gearwheel, which is connected in a rotationally fixed manner to the crank section, and the ring gear, in order to enable a smooth engagement.
  • intake valves 14 and exhaust valves 15 are also indicated, which can be actuated in the usual way via camshafts.
