Definitions

  • the present invention relates to a piston compressor with at least two pistons and a rotary drive.
  • the invention relates to such piston compressors that work with dry-running pistons.
  • Such pistons have plastic seals and the disadvantage that they tip in the cylinder. This limits performance and stability. In addition, energy is lost due to bearing and sliding friction.
  • the control of the inlet and outlet can be done in the usual way by valve or slot control.
  • a valve control acting axially in the piston is preferably used for at least the supply air.
  • These controls are known and are not the subject of the present application.
  • the principle can also be used vice versa for an engine.
  • a high-tension medium such as compressed air or the like can be used as the energy source.
  • the machine can also be operated as an internal combustion engine with internal combustion of a gaseous or liquid fuel. The mode of operation is reversed. Compressed air or a liquid or gaseous fuel is supplied, which causes the pistons to move back and forth.
  • the pistons coupled in pairs provide an output shaft in a rotating movement via the eccentric drive, which can be removed for any mechanical work.
  • the main advantage results from the fixed connection of two pistons that support each other. This prevents any tilting of the pistons in the cylinder.
  • the piston rod receives its movement via its eccentric drive, whereby advantageously only two bearings are sufficient for two pistons instead of the otherwise necessary four bearings.
  • a short design can be achieved in that the fixed piston rod has a link-like recess through which the crank mechanism can protrude.
  • compressors can be designed in a simple manner at least in two stages or with a multiple of two pistons each that are driven by a drive shaft 1 e.
  • An engine can also be designed with several pistons.
  • FIG. 1 shows a schematic plan view of a tandem piston with an eccentric drive
  • Fig. 2 is a schematic representation of a double Kol ben with a modified eccentric in a Kol benstel 1 ung;
  • Fig. 3 is an illustration like Figure 2 in a different position of the pistons and
  • FIG. 4 shows a section along the section plane IV-IV in FIG. 2.
  • a compressor for compressing air with at least two interconnected pistons 10 and 12, which is driven by a drive, for example, an electric motor not shown here via a shaft 18 so that the piston 10 in one Cylinder 14 and the piston 12 is reciprocable in a cylinder 16.
  • the rotating movement of the shaft 18 is rigid and a reciprocating movement of one of the two pistons 10 and 12 and one of these two pistons via a specially designed drive *
  • the shaft 18 is connected to an eccentric 24 with eccentric pin 25.
  • a gear rod 30 is placed by means of a bearing 28 so that the force introduced by the pin 26 is transmitted via the gear rod 30 to a pin 34 which is laterally firmly connected to the piston rod 20.
  • a bearing 32 is located between the gear rod 30 and the pin 34. The kinetic energy is introduced through this connection 32, 34 into the piston rod 20, which carries the firmly attached pistons 10 and 12 at both ends.
  • These are of short axial construction and preferably move as intermediate runners in cylinders (not shown in FIG. 1) in which they compress air.
  • the advantage of the two pistons 10 and 12 connected by means of a rigid piston rod 20 is that these pistons 10, 12 no longer tilt in the cylinder, since they are mutually supported against the corresponding cylinder walls. This makes the seal easy. It is sufficient for each of the two pistons 10, 12 an annular seal, for example made of a suitable plastic.
  • the further advantage is that for two pistons and cylinders, for which two bearings are normally required per piston in a conventional crank and connecting rod drive, four bearings would therefore be necessary for two pistons, according to the invention only two bearings, namely the bearings 28 and 32 are sufficient for two pistons 10 and 12, as a result of which power losses and mechanical problems are reduced.
  • FIG 1 A modification of the one shown in FIG 1 illustrated principle, which is maintained, after which can be built short in the direction of the drive shaft.
  • the bearing 32 engages around a bolt 36 which engages on a specially designed piston rod 22.
  • the piston rod 22 has a recess 38 which portions of the benstangen-bracket Kol are at a distance 40 and 42.
  • the pieces 40 and 42 converge in end parts 44 and 46 above and below the recess 38 before the pistons 10 and 12 are firmly attached.
  • the piston rod 22 in this embodiment forms in its own movement plane with the recess 38 space for the protrusion of the eccentric 24 and the articulation of the gear rod 34.
  • the axial construction can be shortened.
  • This can be further improved in that a reinforcing rib 48 is guided on one or both sides from the end piece 44, around the recess 38 on the bracket sections 40 and 42 to the end part 46 (FIG. 2).
  • a double-piston unit is produced which can be operated at high speeds, the pistons of which support one another in the corresponding cylinder and which requires fewer bearings than conventional piston drives.
  • the pistons can each be a pair that work in two cylinders of a two-stage compressor connected in series. For this only need
  • Piston diameter to be varied accordingly.
  • a piston with a large diameter works in a pre-compression stage and a piston with the same stage with a smaller diameter works in a post-compression stage.
  • several such double piston arrangements can be driven side by side from one drive, since with the kul ssen-shaped design of the piston rod, a drive shaft 18 can be axially extended through the recess 38.
  • the pin 27 need only be designed as a pin of a multi-arm crank in order to be able to continue the shaft 18 beyond the bearing 28.

Abstract

Pour un compresseur fonctionnant à sec, muni d'au moins deux pistons, ceux-ci sont réunies rigidement à l'aide d'une tige (22). La tige (22) est actionnée par l'intermédiaire d'un excentrique (24, 26) à partir d'un mouvement rotatif. La tige peut laisser passer l'entraînement à excentrique à travers un évidement. Des compresseurs à plusieurs étages, munis de deux ou d'un multiple de deux pistons, peuvent être réalisés. Le même principe peut être inversé pour réaliser une machine motrice dans laquelle le piston peut être mis en mouvement à l'aide d'un combustible gazeux ou liquide par combustion interne ou à l'aide d'un gaz sous pression.
