Definitions

  • This invention relates to a compressor, preferably used in refrigerators, which comprises a muffler that minimizes the noise generated by the refrigerant during the refrigeration cycle and, a cylinder head that is used to attach the muffler to the cylinder.
  • suction mufflers are utilized to ensure that the refrigerant used to achieve the cooling reaches the cylinder block without being heated and, that the noise that might be generated by the said refrigerant is prevented.
  • the suction muffler is generally manufactured from plastic material and located either on the cylinder head or between the cylinder head and the valve plate. The refrigerant sucked, reaches a cylinder block by passing through a muffler wherein its portion forming the suction manifold is placed inside the cylinder head. While attempting to minimize the noise generated, it is necessary to improve thermodynamic efficiency. However, heat transfer occurs at the section where the cylinder head and the muffler head are connected, such that the refrigerant and correspondingly the thermodynamic cycle are affected.
  • the cylinder head is manufactured in single piece and a portion of it is in full contact with the surfaces of the muffler that form the suction manifold.
  • the temperature of the refrigerant sucked into the cylinder rises because of the temperature difference formed at the cylinder head as a result of the discharge of the refrigerant to the exhaust manifold of cylinder head after leaving the cylinder, wherein both the pressure and temperature of the said refrigerant are increased by the compression process in the cylinder.
  • the rise in the temperature of the refrigerant causes its volume to increase thereby resulting in compression of less amount of refrigerant in a standard stroke volume and, decrease of volumetric efficiency of the compressor.
  • the aim of the present invention is the realization of a compressor wherein it is achieved that the refrigerant is transferred to the cylinder without its temperature being increased at the section where the muffler and the cylinder head are connected together and therefore, that the volumetric efficiency is increased.
  • Fig.1 - is a sectional view of a compressor.
  • Fig.2 - is a perspective view of a cylinder head and a suction muffler.
  • Fig.3 - is a top view of a cylinder head and a suction muffler.
  • Fig.4 - is an exploded view of a cylinder head, a valve plate and a suction muffler.
  • Fig.5 - is a perspective view of a cylinder head and a muffler head.
  • Fig.6 - is a bottom perspective view of a cylinder head and a muffler head.
  • Fig.7 - is a top view of a cylinder head and a muffler head.
  • Fig.8 - is a top perspective view of a cylinder head and a muffler head.
  • Fig.9 - is a bottom perspective view of a cylinder head and a muffler head, in another embodiment of the present invention.
  • Fig. 10 - is a top perspective view of a cylinder head and a muffler head, in another embodiment of the present invention.
  • Fig. 11 - is a top view of a cylinder head and a muffler head, in another embodiment of the present invention.
  • the circulation of the refrigerant used to realize the cooling is achieved by means of a hermetic piston compressor (1).
  • the compressor (1) comprises a cylinder (2) which provides the pumping of the refrigerant in it, a cylinder head (3), located above the cylinder (2), whereby the refrigerant that is sucked and discharged is circulated, a valve plate (5) between the cylinder (2) and cylinder head (3), above which the cylinder head (3) is placed, a suction muffler (4) with insulating properties, placed onto the cylinder head (3), and preferably made of plastic material, wherein acoustical energy of the refrigerant circulated inside it, is reduced thereby minimizing the noise generated during the circulation and, which ensures that the refrigerant reaches the cylinder head (3) without being heated.
  • the suction muffler (4) comprises a muffler head (8) whereby it is attached to the cylinder head (3) and, an outlet opening (6) on the muffler head (8) permitting the refrigerant to pass to the cylinder (2) therethrough.
  • the cylinder head (3) comprises a muffler head housing (7) into which the muffler head (8) fits, an exhaust volume (9) wherein the refrigerant discharged from the cylinder (2) is circulated and, a bridge (12) whereby the upper edges of the muffler head housing (7) are connected together and, the muffler head (8) is fixed inside the muffler head housing (7).
  • the muffler head (8) and the muffler head housing (7) incorporate one or more extensions (10) used to connect to each other and, one or more recesses (11) where the extension (10) is fitted.
  • the muffler head (8) and the muffler head housing (7) are in contact with each other only at the mentioned extension (10) and recess (11) and between them, there is provided a gap (B) functioning as an insulator, whereby it is achieved that the heat transfer is reduced by minimizing the contact of the muffler head housing (7) with the hot portions of the cylinder head (3) and, that the refrigerant is prevented from being heated.
  • the recess (11) is positioned on the muffler head (8) whereas the extension (10) that is used to fix the muffler head (8) by fitting it into the said recesses (11) is positioned on the muffler head housing (7).
  • the extension (10) is positioned on the muffler head (8) whereas the recess (11) where the extension (10) is fitted into is positioned on the muffler head housing (7).
  • At least one extension (10) in the form of a pin is positioned on the bridge (12) whereas recesses (11) in a form and amount appropriate with the said extensions (10) are positioned on the muffler head (8) (Fig.6, Fig.7, Fig.8).
  • the extensions (10) in the form of a triangle prism, positioned at the both lateral surfaces of the muffler head housing (7), are fitted into the recesses (11) positioned at the lateral surfaces of the muffler head (8), which are suitable for the extensions (10) from the aspects of form, position and number.
  • the muffler head (8) and the muffler head housing (7) are located so that up and down motion is prevented as a result of the triangle prism forms of the extensions (10) and recesses (11), and are fastened to the valve plate (5) wherein their front and back motion is prevented by means of the bridge (12) placed on the said extensions (10) and, except for the extensions (10) and the recesses (11), a gap (B) reducing the heat transfer is left in between (Fig.9, Fig. 10, Fig. 11).
  • the muffler head housing (7) comprising an extension (10) with projections in different directions which are utilized to prevent motion in different directions, is placed on the muffler head (8) comprising an recess (11) suitable for the said extension (10) from the aspects of form and position and, is fastened to the valve plate (5) by means of screws wherein between the mentioned muffler head housing (7) and the muffler head (8), except for the extensions (10) and the recesses (11), a gap (B) reducing the heat transfer is left (Fig.5).
  • the contact surface of the muffler head housing (7) and the muffler head (8) is reduced, resulting in that the refrigerant is taken into the cylinder cooler and thus denser and thereby, it is achieved that the performance of the compressor (1) is increased.
