Definitions

  • the present invention relates to a linear compressor, in particular a linear compressor, which is suitable for compressing refrigerant in a refrigerator.
  • Out EP 1 126 171 A2 is a linear compressor having a pumping chamber in which a piston is reciprocable, a fixed to the pumping chamber frame on which a vibrating body via at least one spring is movable back and forth, mounted on the frame electromagnet for driving the Hin- and reciprocation of the vibrating body and a piston rod connecting the vibrating body to the piston.
  • the spring is a diaphragm spring, the edge of which is fastened to the annular space surrounding the pumping chamber and screwed to the center of the cup-shaped oscillating body and one end of the piston rod.
  • the other end of the piston rod is spherical and engages a cup formed on the piston so that the piston rod and the piston are pivotally movable with respect to one another.
  • the pivotal mobility prevents the transmission of torque from the vibrating body via the piston rod to the piston, which could cause the piston in the pumping chamber to tilt and become difficult to move.
  • the piston In order to achieve sufficient security against tilting, the piston must have a considerable length. Accordingly, a lot of space for the piston is required in the pumping chamber, so that the ratio of pumping chamber volume to throughput is rather unfavorable.
  • the piston rod can also transmit transversely to the direction of movement of the piston in the pumping chamber oriented forces on the piston, which press this against a side wall of the pumping chamber.
  • a sliding contact between the piston and the side wall would lead to considerable frictional wear, so that it is proposed in this document between the side wall and the piston, an air bearing to prevent such contact, by compressed gas from the high pressure side of the linear compressor branched off and openings in the side wall is returned to the pumping chamber.
  • the gas film formed along the side wall prevents direct contact between the pump chamber wall and the piston, if the gas flow rate is high enough.
  • FR 743 398 A discloses a linear compressor according to the preamble of claim 1.
  • a piston rod with a piston and a vibrating body via a respective ball joint is connected to allow a transmission even in the case of deviating movement directions of the piston and the oscillating body.
  • the object of the invention is to provide a linear compressor which minimizes the transmission of lateral forces from the oscillating body to the piston with a simple structure.
  • the first joint preferably connects the Studentstange with a rigidly anchored to the piston and guided in the pumping chamber piston rod.
  • FIG. 1 in a perspective view shown linear compressor has a rigid, in plan view in approximately U-shaped frame, which is composed of three parts, namely two flat wall pieces 1 and a sheet 2. Between facing narrow sides of the sheet 2 and the two wall pieces 1, a first diaphragm spring 3 is clamped; a second diaphragm spring 4 of the same shape as the diaphragm spring 3 is attached to the side facing away from the bow narrow sides of the wall pieces 1.
  • the stamped from spring plate diaphragm springs 3, 4 each have an elongated edge strip which covers the narrow sides of the wall pieces 1, and four spring arms 5 which extend in a zigzag from the ends of the edge strips to a central portion 6, where they meet.
  • the central portion 6 has three holes, two outer to which by means of screws or rivets 7, a permanent magnetic oscillating body 8 is suspended, and a central bore through which in the diaphragm spring 3 a to the oscillating body 8, z. B. by screw fastened rod portion 10 extends.
  • the rod portion 10 is connected to a transmission rod 9 formed in the present case of spring steel via a flexibly flexible tapered portion 11.
  • a second tapered portion 12 connects the transmission rod 11 integrally with a piston rod 13, which engages in a pumping chamber 14 supported by the arc 2, is guided through a bore in an end wall of the pumping chamber and in the pumping chamber 14 with a movable piston 15 (see FIG. 2 ) connected is.
  • Two electromagnets with an E-shaped yoke and a coil wound around the middle leg of the E are respectively arranged between the oscillating body 8 and the wall pieces 1 with the oscillating body facing pole pieces and serve to drive a vibrating movement of the oscillating body 8.
  • the piston 15 Since the piston rod 13 rigidly connected to the piston 15 is guided in the frontal bore of the pumping chamber 14, the piston 15 is protected against tilting, even if its extension in the direction of the reciprocating motion is small. The piston 15 therefore occupies little space in the pumping chamber 14, so that a large effective volume is achieved with small outer dimensions.
  • the pumping chamber 14 is annularly surrounded by a cavity 16 which communicates with the pumping chamber 14 through a plurality of openings 17 in its side wall and which is fed via a passage 18 with compressed gas branched from a pressure port 19 of the pumping chamber.
  • the penetrating through the openings 17 in the pumping chamber 14 compressed gas forms on the side wall a cushion on which the piston 15 slides substantially frictionless.
  • the Studentstragerstange 9, as in FIG. 2 shown, straight between the vibrating body 8 and the piston 15, and the directions of movement of the vibrating body 8 and the piston 15 are exactly parallel.
  • deviations from such an ideal configuration always occur due to manufacturing tolerances, be it that the pump chamber 14 is not exactly aligned with the oscillating body 8, or that due to tolerances in the attachment of the diaphragm spring 3, 4 on the frame and the oscillating body. 8 the direction of movement of the oscillating body 8 does not coincide with that of the piston 15.
  • FIG. 3 shows in one too FIG. 2 analogous representation of the case of a lateral offset between the oscillating body 8 and the piston 15.
  • the longitudinal axes of the head portion 10 and the piston rod 13 are parallel, but not collinear. The deviation is absorbed by a slight elastic bending of the tapered portions 11, 12 and a slight inclination of the Mattertragerstange 9.
  • the piston 15 reciprocates in the pumping chamber 14, without him acting significant tilting torques or lateral forces that the piston 15th Press against a wall of the pumping chamber 14.
  • the clearance between the piston 15 and pump chamber wall can therefore be kept small, so that only a small gas flow rate is required for the storage of the piston 15 and a correspondingly high efficiency of the compressor can be achieved.
  • FIG. 4 shows the case of a not exactly parallel alignment of the directions of movement of oscillating body 8 and piston 15. This is compensated by means of the flexible tapered sections 11, 12, wherein the Kochtragerstange 9, as shown by dashed lines, between the reversal points of their movement not only one Shift, but also performs a slight twist.
