Definitions

  • the invention relates to a compressor with at least one Compressor unit as defined in the preamble of the claim 1.
  • a piston compressor is known from the document WO 85/02232, where two pistons compress in separate cylinders.
  • the two pistons are by a rigid, rigid piston rod in an axial alignment with each other connected.
  • a rotary drive is offset via an eccentric drive the pistons coupled in pairs in a linear back and forth Motion.
  • the rotary drive engages on the side of the eccentric Piston rod, which causes the piston rod and the piston eccentric forces and torques are generated.
  • These eccentric forces and torques have one high wear and tear and thus limit the service life of the compressor. But they also brake the piston speed and thus limit the performance of the compressor.
  • the present invention has for its object a to create improved compressor, which compressor in particular can transmit large piston forces, of simple construction is, long maintenance intervals and a long service life guaranteed and with common and proven techniques and standards mechanical engineering can be produced.
  • the invention is based on a consequent separation of support and drive a compressor.
  • the compressor has at least one compressor unit that consists of two pistons, two cylinders and a connecting element.
  • the compressor unit and its elements are along one common longitudinal axis aligned, the pistons and cylinders are aligned with each other along this longitudinal axis, whereby the connecting element between the pistons and this connects each other and in each cylinder a piston back and forth Float.
  • the two pistons of the compressor unit are through the connecting element angularly rigidly connected. Stabilize the pistons with each other in their cylinders and in one large distance from each other, without being one further storage for the connecting element is required.
  • the compressor unit is driven by a connecting rod, the is mounted eccentrically on a shaft and driven by it becomes.
  • the connecting rod is attached to the connecting rod eye Shaft attached and it is on a connecting rod bearing on the compressor unit appropriate.
  • the connecting rod lies in the longitudinal axis of the Compressor unit.
  • the connecting rod bearing is in operation of the compressor permanently in the longitudinal axis of the compressor unit, while the connecting rod eye rotates about the longitudinal axis of the compressor unit cutting axis of the shaft.
  • the driving force is thus directly in the longitudinal axis of the Compressor unit, especially in the one lying on the longitudinal axis Connection element directed.
  • the Connecting rods only pressure and tensile forces from the shaft to the pistons, which is particularly important for large forces to be transferred Minimize the load on the connecting rod bearings and maximize it of the connecting rod bearing life.
  • the connecting element aligned symmetrically to the longitudinal axis of the compressor unit and forms a cage around the connecting rod.
  • the connecting rod lies so on the longitudinal axis of the compressor unit in the connecting element.
  • the connecting rod is at least in the area of the connecting rod eye by side struts of the cage surrounded and the connecting rod is in the area of the connecting rod bearing surrounded by fork-like end portions of the cage.
  • the shaft is also symmetrical to the longitudinal axis of the Compressor unit in the area of the connecting rod eye and protrudes into the cage of the connecting element or through the cage of the Connection element through.
  • the shaft intersects the axis of the compressor unit in equidistance to the cylinders.
  • the connecting rod bearing on one end of one of the pistons attached to the compressor unit, in the area of Connection of the piston to the connecting element.
  • the face is outside the piston.
  • the connecting rod is therefore not as usual in the prior art, in Inside of the piston, namely at the bottom of the piston, but on the outside, outside one bounded by a piston wall Piston chamber stored.
  • This has another advantage, namely that as little heating as possible when the compressor is in operation the connecting rod bearing through the heated piston or cylinder occurs, resulting in long maintenance intervals and a long service life of the connecting rod bearing.
  • This is a heat transfer minimized from the piston or cylinder to the connecting rod bearing and it heat transfer from the connecting rod bearing to the environment is maximized.
  • the compressor can be used with two or more compressor units in a star arrangement along two or arrange several axes.
  • the compressor units are at a distance arranged to each other, they are shared by one Shaft driven.
  • the compressor has a star design, with two in one plane vertical compressor units.
  • the cylinders are equidistant from the shaft and in the plane on a circle arranged perpendicular to the axis of rotation of the shaft.

  • the connecting element 3 is fixed and rigid so that the pistons 1, 1 ', 1' ', 1' '' along the Longitudinal axis AA ', BB' are angularly interconnected.
  • Pistons 1, 1 ', 1' ', 1' '' are thus supported by the connecting element 3 off each other so that they can reciprocate along the longitudinal axis AA ', BB' of the compressor unit 123, 123 'cannot misjudge. This mutual support the piston 1, 1 ', 1' ', 1' '' takes place on the cylinder inner walls.
  • two pistons 1, 1 'via a connecting element 3 firmly connected As in the embodiment of a compressor according to FIG. 2, for example are shown, two pistons 1, 1 'via a connecting element 3 firmly connected.
  • the connection of the pistons 1, 1 'to the connecting element 3 takes place, for example Screw connections.
  • One end each from the connecting element 3 is at least one screw connection on the end face 10, 10 'of a piston 1, 1' attached.
  • the specialist are at Knowledge of the present invention diverse variations available in this regard. So of course there are other mounting options possible as screw connections, for example adhesive or riveted connections are possible.
  • the pistons 1, 1 ', 1' ', 1' '' each limit a compression space inside, at the bottom of cylinders 2, 2 ', 2' ', 2' ''.
  • the pistons are moved back and forth along the longitudinal axis AA ', BB' the compression spaces are more or less limited, for example becomes a recessed compression space Gas is compressed by reducing the compression space. The compressed gas will come out in the compressed state left the compression space.
  • the compressor is driven by a rotary drive 6.
  • the rotary drive is one Electric motor in an embodiment according to FIG. 3.
  • the rotary drive drives a shaft 4 to rotate about one Axis ZZ 'on.
  • the rotational movement of the shaft 4 is in FIGS. 1, 2 and 4 represented by a curved arrow.
