Definitions

  • the present invention relates to a compressor comprising a suction muffler that minimizes the noise generated by the fluid in the refrigerant cycle and a cylinder head which provides the connection of the suction muffler to the cylinder.
  • a suction muffler made from plastic material is used for attenuating the noise originating from the refrigerant fluid and the refrigerant fluid with low temperature coming from the evaporator is delivered to the suction muffler.
  • the sucked circulating fluid reaches the cylinder by passing through the suction muffler of which the part forming the suction manifold is disposed inside the cylinder head. While trying to minimize the noise generated during this process, the thermodynamic efficiency is required to be improved. However, at the regions where the cylinder head and the muffler head are joined, heat transfer occurs such that the thermodynamic circulation is affected due to the circulating fluid.
  • the temperature of the circulating fluid sucked into the cylinder increases due to the heat exchange occurring in the cylinder head.
  • the increase in the temperature of the circulating fluid causes its density to decrease and hence results in a lesser amount of circulating fluid to be compressed in the same stroke volume and the volumetric efficiency of the compressor decreases.
  • the heat transfer between the cylinder head and the muffler head is decreased by reducing the contact area between the cylinder head and the muffler head.
  • the circulating fluid can leak from between the cylinder head and the muffler head since the contact area is small and these losses can cause the pressure of the circulating fluid to decrease.
  • a cylinder head having a shape that decreases the contact surfaces with the suction muffler in order to decrease the heat transfer therebetween.
  • the aim of the present invention is the realization of a compressor with increased operational efficiency.
  • the compressor realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a flange that is disposed on the muffler head so as to surround the outlet port where the circulating fluid is transferred to the cylinder, that entirely fills the height between the muffler head and the housing in the vicinity of the outlet port when the muffler head is placed in the housing on the cylinder head such that the gap therebetween is kept and that bears against the valve plate with its front surface so as to prevent the circulating fluid from leaking out of the cylinder.
  • the circulating fluid while the circulating fluid is being transferred to the cylinder through the muffler head and entering from the muffler head into the suction manifold, by means of the flange the circulating fluid cannot help but move into the cylinder since the flange entirely closes the gap in the muffler head surface facing the cylinder inside the housing, in the vicinity of the outlet port and no gap remains between the housing and the muffler head.
  • the gap between the muffler head and the housing is kept and the temperature of the circulating fluid is continued to be prevented from increasing before being compressed into the cylinder.
  • a recess on the cylinder head facing the housing and a shoulder on the muffler head, inserted into the recess are provided, wherein the recess and the shoulder enforce the leak-proofing of the flange and prevent the muffler head from moving in the housing due to vibrations of the cylinder, and wherein the recess and the shoulder are inserted into one another such that the flange is projected a little towards the valve plate when the muffler head is seated into the housing.
  • the side of the muffler head facing the valve plate projects a little from the cylinder head and the cylinder head is connected to the cylinder, and the flange enables the connection to be tight by pressing on the valve plate.
  • the flange is produced as a single piece with the suction muffler by plastic injection method which is suitable for fast and low-cost mass production.
  • the shoulder is produced as a single piece with the suction muffler by plastic injection method which is suitable for fast and low-cost mass production.
  • the suction muffler is produced so as to comprise the muffler head that has the above explicated flange and shoulder by processing/carving a whole block of plastic.
  • the strength of the suction muffler is increased.
  • Figure 1 – is the cross-sectional view of a compressor.
  • Figure 2 – is the schematic view of detail A in Figure 1.
  • Figure 3 – is the perspective view of the muffler head in an embodiment of the present invention.
  • Figure 4 – is the perspective view of the muffler head in another embodiment of the present invention.
  • Figure 5 – is the exploded view of the cylinder head and the muffler head in an embodiment of the present invention.
  • the circulation of the circulating fluid used for refrigeration is provided by a hermetic reciprocating compressor (1).
  • the compressor (1) comprises a cylinder (2) that provides the compression of the circulating fluid therein; a cylinder head (3) that is connected to the cylinder (2) and that provides the circulation of the circulating fluid; a valve plate (4) that is disposed between the cylinder (2) and the cylinder head (3) and that enables the circulating fluid to be directed; a housing (5) that is disposed on the cylinder head (3) and that provides the transfer of the circulating fluid to the cylinder (2), and a suction muffler (6) wherein the circulating fluid circulates, that minimizes the noise generated during circulation by decreasing the acoustic energy of the circulating fluid, wherein the suction muffler (6) has a muffler head (7) disposed inside the housing (5) such that a gap (B) providing thermal insulation remains between the muffler head (7) and at least some of the walls of the housing (5) and an outlet port (8) that is disposed on the muffler head (7) and that provides the passage of the circulating fluid into the cylinder (2) ( Figure 1).
  • the circulating fluid is transferred into the suction segment of the cylinder (2) through the muffler head (7) and is compressed there to be delivered into the exhaust segment and leaves the compressor (1).
  • the suction muffler (6) can be produced having different designs so as to aim at decreasing the noise generated due to movement of the circulating fluid.
  • an air gap (B) is formed by decreasing the contact area between the muffler head (7) and the housing (5) wherein the muffler head (7) is placed on the cylinder head (3) and thus heat transfer is decreased.
  • the suction muffler (6) comprises a flange (9) that is disposed at the end portion of the muffler head (7) pressing on the valve plate (4), that fills in the gap (B) by surrounding the muffler head (7) in the vicinity of the outlet port (8), that extends towards the inner wall of the housing (5) in the radial direction and that extends towards the valve plate (4) in the axial direction so as to contact the latter ( Figure 3).
  • the flange (9) surrounds the portion of the muffler head (7) in the vicinity of the outlet port (8) such that the gap (B) between the muffler head (7) and the housing (5) is kept and when the muffler head (7) is seated in the housing (5), the flange (9) fills in the gap (B) in the radial direction on the surface of the cylinder head (3) joined with the cylinder (2) or in other words in the vicinity of the outlet port (8).
  • the flange (9) When the cylinder head (3) is mounted to the cylinder (2), the flange (9) extends in the axial direction so as to press on and contact the surface of the valve plate (4) and thus when the cylinder head (3) is connected to the cylinder (2), the circulating fluid is prevented from leaking through the gaps between the housing (5) and the muffler head (7).
  • the flange (9) does not entirely cover the upper portion of the muffle head (7) and the gap (B) that decreases heat transfer between the muffler head (7) and the housing (5) keeps its presence ( Figure 2).
  • the compressor (1) comprises a recess (10) that is disposed on the inner wall of the housing (5) and a shoulder (11) that is disposed on the muffler head (7), that is seated in the recess (10) and that enables the flange (9) to project a little (like 0.1 – 1 mm.) from the housing (5) in the axial direction and to be positioned to press on the valve plate (4).
  • the flange (9) that surrounds the outlet port (8) is enabled to bear tightly on the valve plate (4) and as the shoulder (11) is seated into the recess (10), the leak-proofing maintained by the flange (9) is improved and furthermore the muffler head (7) is prevented from getting loose and causing leakage by being affected with the vibrations of the compressor (1) ( Figure 2 and Figure 4).
