Definitions

  • Double-acting 4-cycle Stirling engines are named in different variants of the Siemens arrangement. In these engines, 4 cylinders are next to each other and each has an expansion and a constellation space.
  • the DE 38 34 071 A1 discloses a stirling-type heat engine wherein motions of two cold pistons are phase-shifted by substantially ninety degrees to two hot pistons. The backs of the two cold pistons are connected by rods. The same applies to the corresponding hot piston. Between the two cold pistons and the two hot pistons a gear is arranged with a swash plate, which is connected to the upper piston via connecting rods.
  • This device has the following disadvantages: It is a 2-cycle Systam that has a non-uniform torque curve over a 4-Zy-Iden machine and requires a flywheel.
  • the power density of the machine is lower because of the single-acting pistons than in double-acting systems.
  • the transmission is heated by axial heat conduction along the cylinder walls (10, 10 ') and the piston (16, 16') and thereby thermally loaded In addition, these losses reduce the operating yield of the machine.
  • the invention describes an alpha-type 4-cycle Stirling engine (4ZM) with 2 double-piston units moving in phase offset with each other, each consisting of 2 pistons connected to piston rods (3), (8) and piston rod extensions (FIGS. 4), (9), the top of a gearbox are in mechanical communication.
  • 4ZM 4-cycle Stirling engine
  • a double piston unit may consist of an expansion piston and a compression piston, 2 expansion pistons or 2 compression pistons.
  • the cylinder space above piston 1 is connected to the cylinder space above piston 7 via the first heater-regenerator-cooler assembly and the cylinder space below piston 1 is with the cylinder space below piston 7 via the second receiver-regenerator-cooler assembly connected.
  • the cylinder space above piston 6 is connected to the cylinder space below piston 2 upper the third heater-regenerator-cooler assembly and the cylinder space below piston 6 is connected to the cylinder space above piston 2 via the fourth Erthitzer regenerator cooler Assembly connected.
  • the first piston of a double piston unit can be used as a guide for the second, it is possible to work without piston rings with a defined annular gap.
  • the double-acting pistons of the double-piston units can be realized as diaphragms or bellows which can be used on both sides, preferably in an outer, pressure-tight enclosing wall.
  • the cylinders for the pistons (1), (2), (6) and (7) may differ in their diameters from each other. As a result, for example, the expansion spaces can be made larger than the compression spaces. In addition, the variation of the cylinder diameter allows a system optimization in the simultaneous realization of right- and left-handed processes (description see below).
  • It can be a heater used in the 4 consecutive or 4 pairs wound single-tube spirals are arranged in a hollow cast body.
  • the burner can be located inside the casting body.
  • the 4ZM can be installed in front of the matrix, a flow body, which has a low flow resistance on both sides, the gas evenly distributed and is preferably a ball.
  • the cyclic short-circuit valves (27) and (28) can be used to control the participating cycles in partial load operation.
  • a further arrangement according to the invention describes a 4-cycle universal machine with 2 double-piston units which move with a phase offset to each other, in which 2 cycles of mechanical energy supply and the two remaining cycles are used to cool heat sources and heat heat sinks.
  • the four working gas areas of the heater 10 in FIG. 1 reduced to two, namely those of cycle 1 and cycle 2.
  • the remaining working gas portions of the heat supply in cycle 3 and cycle 4 which are then no longer in the heater (locally and thermally separated), are thermally connected to one or two heat sources.
  • the areas of heat removal from Cycle 3 and 4 can be connected to one or two heat sinks.
  • cycles 3 and 4 can be used to provide the mechanical energy and cycles 1 and 2 for the cooling processes.
  • Equally obvious is the alternative application of a heat pump instead of a chiller.
  • Cycle 1 and 2 uses as thermal power processes, cycle 3 as a chiller and cycle 4 as a heat pump.
  • cycle 3 uses as a chiller
  • cycle 4 uses as a heat pump.
  • the working gas areas of the heat supply of cycle 3 and cycle 4 must be thermally separated because of the different temperature levels.
  • the machine can also be configured so that the cylinder space above piston 1 is connected to the cylinder space above piston 6 via the first heater-regenerator-cooler assembly and that the cylinder space below piston 1 with the cylinder space below piston 6 via the second heater-regenerator-cooler assembly is connected.
  • the cylinder space above piston 2 is connected to the cylinder space above piston 7 via the first heat source regenerator heat sink assembly and the cylinder space below piston 2 is connected to the cylinder space below piston 7 via the second heat source regenerator heat sink assembly. Assembly connected.
  • a further arrangement according to the invention of the machine is that the cylinder space above piston 1 is connected to the cylinder space below piston 7 via the first heater-regenerator-cooler assembly and that the cylinder space below piston 1 with the cylinder space above piston 7th connected via the second heater-regenerator-cooler assembly.
  • the cylinder space above piston 2 is connected to the cylinder space below piston 6 via the first heat source regenerator heat sink assembly, and the cylinder space below piston 2 is connected to the cylinder space above piston 6 via the second heat source regenerator heat sink assembly. Assembly connected.
  • a gear to achieve the phase offset and energy conversion can also be realized in the form of a linear generator linear motor system.
  • magnet or bobbins are attached to the piston rod extensions, which interact with outer stationary coil or magnetic bodies.
  • the energy surplus of a double-piston unit can be used in this way to drive the other double-piston unit.
  • the linear generator linear motor systems change permanently between generator and motor operation.
  • a linear generator linear motor system in connection with the arrangement of the two double piston units in boxer form.
  • the movable and fixed coil and magnetic body of both double piston units can then be partially or completely united.
  • the arrangement of the double piston units according to FIG. 1 and the Boxer form is also a V-arrangement with connection to only a common Kurbelwellenkröpfung feasible.
