Description

    A HERMETIC COMPRESSOR WITH IMPROVED SEALING
  • The present invention relates to a hermetic type compressor suitable for use in cooling devices.
  • In hermetic compressors, the refrigerant is sucked from and pumped back to the refrigeration cycle by means of a piston operating in a cylinder. In hermetic compressors, the refrigerant with increased pressure and temperature while the refrigerant in the cylinder volume is compressed by the piston fills into the exhaust chamber in the cylinder head and from there is sent to the refrigeration cycle. The cylinder head in the compressor compensates the compressive stress occurring due to the compression of the refrigerant as a result of the piston movement and enables the refrigerant with high temperature and pressure to be delivered to the exhaust muffler. After being compressed by the piston and reaching a high pressure, the refrigerant is directed to the exhaust chamber, and the pressure difference between the interior of the compressor casing and the exhaust chamber in the cylinder head. In this case, the refrigerant leaks into the interior of the casing through the walls of the cylinder head and valve table, casing pressure losses due to the passage of the refrigerant into the casing and decreasing the pressure of the refrigerant introduced into the refrigerant cycle. Moreover, the mixing of the refrigerant with the lubricant in the casing causes a decrease in the refrigerant amount and lubrication problems.

  • The compressor realized in order to attain the aim of the present invention is explicated in the claims.
  • The hermetic compressor comprises a valve table that is disposed between the cylinder and the cylinder head, that enables the refrigerant sucked from and pumped to the refrigeration cycle to be guided and whereon suction and exhaust ports and valves are disposed, and a cylinder heat that enables the pumped refrigerant to be directed. A plastic insulating plate is disposed between the valve table and the cylinder head so as to provide leak-proofing. In the embodiment of the present invention, in order to improve the leak-proofing between said insulating plate and the cylinder head, a channel that peripherally extends at the inner side of the edges of the cylinder head is provided, and a protrusion that is arranged on the surface of the insulating plate seated on the cylinder head and that is fitted into said channel is provided.
  • In an embodiment of the present invention, while the cylinder head is being mounted, the protrusion is press-fitted into the channel.

  • In another embodiment of the present invention, in addition to said channel and protrusion, cavities are provided on the cylinder head and pins that are fitted into said cavities are provided on the insulating plate.
  • In the compressor of the present invention, the leak-proofing between the cylinder head and the valve table is improved, refrigerant losses are prevented and the performance is increased.
