Definitions

  • the present invention relates to a compressor with improved performance, whose vibration and noise levels are reduced.
  • the electric engine used in driving a crank-connection rod mechanism, the cylinder-piston mechanism and other mechanisms are disposed in a sealing housing.
  • the loss occurring due to the efficiency of the electric engine being in the range of 70-80%, and the mechanical losses taking place particularly on the bearings, cause the parts in the compressor to heat up, and the volumetric yield to decrease due to the increased temperature of the coolant before entering the cylinder.
  • the vibration and the noise arising from the operation of the electric engine are sought to be reduced by keeping the electric engine on a plane by means of a plurality of springs, one ends of whose are fixed to the electric engine and the other ends to the housing. Higher the number of connection of the springs to the housing, more vibration and noise are transmitted to the housing.
  • an electric engine is suspended by four springs.
  • One ends of these springs are mounted to the spring retainers fixed on the housing by spot welding, and the other ends are mounted to the spring retainers fixed to the stator.
  • the aim of the present invention is to realize a compressor with reduced levels of vibration and noise.
  • the compressor realized to achieve the aim of the present invention and disclosed in the first claim and the dependent claims comprises at least one first coupling member whose ends are coupled to the engine and the housing, and at least one second coupling member coupled to the first coupling member.
  • the number of connections from the first and the second coupling members to the engine or the housing is thus reduced by at least one.
  • the compressor comprises at least one first coupling member whose one end is coupled to the engine and the other end to the housing, and at least one second coupling member coupled from at least one end to the first coupling member.
  • the compressor comprises a first coupling member whose one end is coupled to the engine and the other end to the housing, and one or more second coupling members whose at least one end coincides with the end of the first coupling member fixed to the engine or the stator.
  • the compressor comprises coupling members fixed from one end each to the engine, and fixed from a single point to the housing by joining at the center of the compressor.
  • first and the second coupling members fixed to the engine at the same point are coupled to the housing at separate points.
  • the compressor comprises at least two bases extending on the horizontal plane, disposed at the portion where the first and the second coupling members are fixed to the engine, to the housing or to each other, and two arms which are preferably "V" shaped, extending between the bases with a wide angle in between.
  • the first and the second coupling members are fixed to the engine, to the housing or to each other via the bases by means of fastening members.
  • a base is provided on both ends and the middle of the first and the second coupling members, and the two arms are disposed between the base at the middle and the bases at both ends.
  • the first and the second coupling members are springs.
  • leaf springs are used as springs.
  • an engine in a compressor is enabled to be suspended by means of coupling members, it is enabled to transmit to the housing at the minimum level vibration and noise arising from the operation of the engine, thereby minimizing the vibration and the noise levels of the compressor.
  • Figure 1 is a schematic view of a compressor.
  • Figure 2 is an exploded view of the engine, housing, and the first and the second coupling members.
  • Figure 3 is a side view of the first and the second coupling members.
  • Figure 4 is a perspective view of the first and the second coupling members in an embodiment of the invention.
  • Figure 5 is a perspective view of the first and the second coupling members in another embodiment of the invention.
  • the compressor (1) of the invention comprises a housing (2) enclosing the movable parts, a crank shaft rotating in the housing (2), and an engine (3) enabling the crank shaft to be rotated, having a stator (4) shaped as a hollow ring, with a ring shaped core and coils wound on the core, and a rotor mounted to the crank shaft by being passed through the space in the center of the stator (4), having a magnet rotating proportionally to the frequency of the feed current on the coils, and
  • the first coupling member (5) is coupled from one end to the engine (3) or to the housing (2), while the second coupling member (6) is coupled to the first coupling member (5).
  • the number of connections from the first and the second coupling members provided between the engine (3) and the housing (2), to the engine (3) or to the housing (2) is thus reduced by at least one.
  • the compressor (1) comprises a first and a second coupling member (5 and 6) fixed from at least one end each to the engine (3), and fixed at a single point to the housing (2) so as to join at the center of the compressor (1).
  • the first coupling member (5) is coupled from both of its ends to the engine (3), and is coupled at its middle to the housing (2).
  • the second coupling member (6) is coupled from both ends to the engine (3), and is coupled from its middle to the first coupling member (5) and via the first coupling member (5) to the housing (2). Therefore, the first and the second coupling members are coupled to the housing (2) not from two points but instead from only a single point ( Figure 3).
  • first and the second coupling members (5 and 6) are fixed via their ends at the same point to the engine (3), and at separate points to the housing (2).
  • the first and the second coupling members (5 and 6) are coupled to the engine (3) such that their two ends coincide, and are separately coupled from their middle portions to the housing (2).
  • the first and the second coupling members (5 and 6) are enabled to be coupled to the engine (3) at two points by superposing two ends of each, instead to couple the first and the second coupling members to the engine (3) from four ends at four separate points as required.
  • the compressor (1) comprises at least one first coupling member (5) whose one end is coupled to the engine (3) and the other end to the housing (2), and at least one second coupling member (6) coupled to the first coupling member (5) ( Figure 4).

  • the first and the second coupling members are fixed through the bases (7) to the engine (3), to the housing (2) or on each other by means of fastening members (9).
  • a base (7) is provided on both ends and the middle of the first and the second coupling members (5 and 6), and the two arms (8) are disposed between the base (7) at the middle, and the bases (7) at both ends.
  • the first and the second coupling members (5 and 6) are springs.
  • leaf springs are used as springs.
  • the coupling members disposed between the engine (3) and the housing (2) are enabled to be fixed to the engine (3) or the housing (2) from the minimum number of points possible. The vibration and the noise levels of the compressor (1) arising from the operation of the engine (3) are thus minimized.
