Definitions

  • the present invention relates to a compressor comprising a cylinder head that is utilized in cooling devices.
  • the refrigerant sucked in from inside the casing reaches the cylinder by passing through the muffler and the 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 suction and exhaust chambers are disposed adjacent to each other in the cylinder head. And consequently a heat transmission from the high temperature refrigerant in the exhaust chamber to the low temperature refrigerant in the suction chamber occurs.
  • the heat transmission between the suction and exhaust chambers causes the temperature of the refrigerant sucked into the cylinder to rise.
  • the rising of the refrigerant temperature entering the cylinder causes an increase in the specific volume of the refrigerant and hence the compression of a lower amount of refrigerant in the same displacement. Accordingly, the compressor efficiency and performance are adversely affected.
  • the suction and exhaust mufflers are predominantly produced from plastic based materials and materials with both heat and oil resistance and also with low thermal conductivity, for example PBT material containing 30 % glass fiber additive, is utilized.
  • the aim of the present invention is the realization of a compressor with an improved performance by preventing the losses resulting from the undesired heat transmission between the suction chamber and the exhaust chamber.

  • the compressor furthermore comprises a valve table situated between the cylinder and the cylinder head.
  • the valve table comprises suction and exhaust ports that provide the entry and exit of the refrigerant into/from the cylinder.
  • bushes are situated at the corners of the framework. The cylinder head is secured on the valve table by means of bushes and consequently damaging of the cylinder head during the installation procedure is minimized.
  • the cylinder head has more than one side wall.
  • the side walls are positioned such that the orifice of the cylinder head facing the suction muffler is open and is formed as an octagon with the lower side open allowing fluid entry into the suction chamber.

  • the cylinder head furthermore comprises an intermediate wall that divides the octagonal structure formed by the side walls into two such that the suction chamber is on one side and the exhaust chamber is on the other side.
  • the framework is a single piece and comprises arms that are embedded into all the side walls of the cylinder head, a diagonal to be embedded in the intermediate wall and bushes arranged on the points the arms intersect and on the open ends. Consequently, the strength of the cylinder head is provided to be increased.
  • the framework comprises arms that are embedded in all the side walls of the cylinder head and besides a diagonal embedded in the intermediate wall, a transverse embedded in the front wall at the lower side corresponding to the suction chamber entrance.
  • Bushes are provided at the intersection points and the open ends of the arms, the transverse and the diagonal.
