Definitions

  • the present invention relates to a compressor used in cooling devices and comprising a cylinder head.
  • the refrigerant reaches the cylinder by passing through the muffler and suction chamber of the cylinder head.
  • the refrigerant with increased pressure and temperature is poured into the exhaust chamber of the cylinder head after leaving the cylinder.
  • the delivery of the refrigerant from the suction chamber to the cylinder is realized by means of the inlet passage situated on the valve plate.
  • the suction valve leaf located in front of the inlet passage opens up the front of the inlet passage by moving towards the cylinder with the effect of pressure difference.
  • the refrigerant passes from the suction chamber to the cylinder.
  • the refrigerant flows back towards the suction chamber by impacting the suction valve leaf.
  • the refrigerant contained in the exhaust chamber while the exhaust valve leaf covers the front of the discharge passage prematurely, flows back into the cylinder by impacting the exhaust valve leaf. Sound is generated due to movements of the refrigerant in opposite directions inside the cylinder, towards the exhaust chamber and towards the cylinder (the movement of refrigerant flowing back by impacting the valve leaf).
  • the refrigerant compressed in the cylinder and delivered to the exhaust chamber increases the temperature at the interior of the suction chamber.
  • the increased heat in the suction chamber disperses outside the suction chamber. Accordingly, the compressor efficiency and performance are adversely affected.
  • JP60065291 a compressor is described having a U-shaped protector that is disposed on the cylinder head.
  • the FR 1 368 173 A discloses a cylinder head for a compressor that is composed of several layers which form cavities for the inlet and outlet of gas.
  • An uppermost layer of the cylinder head comprises a dome for reinforcement purposes.
  • the aim of the present invention is the realization of a compressor wherein the sound and heat generated during the flow of the refrigerant are attenuated.
  • the compressor realized in order to attain the aims of the present invention and explicated in the attached claims, comprises a casing carrying the components therein, a cylinder wherein the compression process is performed, a cylinder head disposed on the cylinder, a valve plate situated between the cylinder and the cylinder head, at least one exhaust chamber below the cylinder head wherein the pumped circulating fluid fills, at least one suction chamber wherein the sucked circulating fluid fills and at least one cover disposed above the cylinder head.
  • the exhaust chamber and the suction chamber are disposed side by side below the cylinder head.
  • the compressor of the present invention furthermore comprises at least one insulation chamber situated between the cylinder head and the cover.
  • the refrigerant flows back by impacting the valve leaf in the case the valve leaf situated on the valve plate is closed.
  • the insulation chamber By means of the insulation chamber, the noise, generated with the mixing of the refrigerant moving towards the valve leaf and the refrigerant flowing back by impacting the valve leaf, is prevented from dispersing outside the cover and insulation is provided.
  • the cover is produced from a material with low heat and/or sound conductivity.
  • the cover disposed on the cylinder head provides heat and sound insulation.
  • the cylinder head is produced from plastic material. Production of the cylinder head from plastic material minimizes heat transmission between the suction chamber and the exhaust chamber.
  • the cover is produced from metal material.
  • a cover having a sturdy structure is disposed on the cylinder head. The cover applies pressure on the cylinder head by means of the surfaces it contacts and prevents a distance from remaining between the cylinder head and the valve plate.
  • the insulation chamber is fixed on the cylinder head by snap-fitting method.
  • a material having low coefficient of insulation is placed into the insulation chamber.
  • sound and heat are prevented from dispersing outside the cover.
  • the insulation chamber is formed as a recess arranged on the cylinder head.
  • the temperature of the compressed refrigerant increases during the delivery of the refrigerant from the cylinder to the exhaust chamber. As the compressed refrigerant flows into the exhaust chamber, the temperature inside the exhaust chamber also increases.
  • the heat is provided to be insulated by means of the insulation chamber being disposed on the exhaust chamber.
  • the insulation chamber is situated between the walls that separate the suction chamber from the exhaust chamber.
  • the insulation chamber is shaped as a recess. Thus, heat exchange between the suction chamber and the exhaust chamber is prevented.
  • the compressor comprises at least one sealing element that surrounds the insulation chamber. Insulation efficiency is increased between the cylinder head and the cover by preventing refrigerant and heat from entering the insulation chamber.
  • the compressor comprises at least one suction muffler having a hollow volume that provides the attenuation of the noise generated during the pumping of the refrigerant fluid, at least one headpiece mounted on the suction muffler and the cylinder head having at least one first housing wherein the suction muffler is disposed.
  • the suction muffler with the headpiece mounted thereon is placed into the first housing.
  • the suction muffler placed into the first housing is situated between the cylinder head and the valve plate.
  • the suction chamber is disposed to be adjacent to the exhaust chamber below the cylinder head.
  • the cover comprises at least one second housing wherein the suction muffler is situated.
  • the second housing is situated just above the first housing.
  • the shapes of the first housing and the second housing are almost the same.
  • the compressor comprises at least one extension that extends from the sides of the cover that surround the second housing and that is situated at least partially on the suction chamber when the cover is placed on the cylinder head.
  • the compressor comprises at least one recess wherein the exhaust chamber and the suction chamber are almost entirely situated.
  • the headpiece is placed into the second housing. Consequently, the suction chamber and the exhaust chamber are provided to be disposed between the cover and the valve plate.
