Definitions

  • the present invention relates to a compressor wherein the circulating fluid is delivered from the suction muffler to the cylinder without a rise in its temperature.
  • suction mufflers are used for delivering the circulating fluid utilized for cooling to the cylinder without heating up and for attenuating the noise that may result from the circulating fluid.
  • the suction muffler is usually made of plastic and is connected to the cylinder head.
  • the sucked circulating fluid passes through the muffler and through the part forming the suction chamber in the cylinder head and reaches the valve plate and the cylinder.
  • the thermodynamic efficiency has to be enhanced at the same time while trying to minimize the noise generated during this passage. Heat transfer that affects the circulating fluid and thereby the thermodynamic efficiency occurs at the parts where the cylinder head is joined to he muffler head.
  • the cylinder head is produced as a single piece and some part of the cylinder head is in contact with the surfaces of the muffler that form the suction chamber.
  • the circulating fluid with increased temperature and pressure leaves the cylinder after the compression process at the cylinder and since it is first delivered to the exhaust chamber of the cylinder head, the temperature of the circulating fluid sucked into the cylinder rises as a result of the temperature change in the cylinder head.
  • the rise in the temperature of the circulating fluid leads to the increase in its volume and thus a lesser amount of the circulating fluid is compressed at the same stroke volume and the volumetric capacity of the compressor is reduced.
  • the cylinder head comprises a front head cover having a low-pressure side sucking a refrigerant and a high-pressure side discharging the refrigerant and a rear head cover combined to the rear surface of the front head cover.
  • the compressor of the present invention comprises a cylinder providing the sucking and pumping of the circulating fluid, a cylinder head situated on the cylinder for guiding the sucked and pumped circulating fluid, and a suction muffler that attenuates the noise resulting from the circulating fluid and the muffler head at the suction muffler outlet is connected to the cylinder head.
  • the muffler head extends over the cylinder head without touching it and when it is aligned with the suction hole under the cylinder head, advances towards the cylinder head by entering through the passage hole on the rear surface of the cylinder head and extending to the valve plate.
  • the front part of the end of the muffler head that is inserted into the cylinder head contacts the periphery of the suction hole on the valve plate by a certain pressure.
  • the muffler head is in J form, with one arm extending forward from the top plate of the suction muffler without touching the cylinder head.
  • the elbow portion of the J shape is aligned with the suction hole covered by the cylinder head, and the arm of the J shape extends from the elbow to the cylinder head, passes through the passage hole and seats to the valve plate.
  • the arm of the muffler head extending from the elbow to the valve plate forms the cylindrical shaped portion.
  • the contact between the passage hole on the cylinder head and the muffler head is minimized, reducing heat transfer and the end of the muffler head is pressingly seated on the valve plate to prevent leakage of the refrigerant fluid thereby enhancing the thermodynamic efficiency.
  • Figure 1 - is the sectional view of a compressor.
  • Figure 2 - is the sectional view in detail D of the compressor in Figure 1.
  • Figure 3 - is the perspective view of a suction muffler head.
  • Figure 4 - is the perspective view of a cylinder head.
  • Figure 5 - is the perspective view of a suction muffler and a cylinder head before being assembled.
  • Figure 6 - is the perspective view of a suction muffler and a cylinder head after being assembled.
  • the circulation of the circulating fluid utilized to provide cooling is preferably achieved by a hermetic reciprocating compressor (1).
  • the compressor (1) comprises a cylinder (2) providing the suction and pumping of the circulating fluid, a cylinder head (3) situated on the cylinder (2) guiding the sucked and pumped circulating fluid, a valve plate (5) on which the cylinder head is positioned, having a suction hole (4) for delivering the circulating fluid to the stroke volume of the cylinder (2) and a suction muffler (6) providing attenuation of the noise resulting from the circulating fluid.
  • the cylinder head (3) comprises a rear wall (7) situated opposite the valve plate (5) covering the suction and exhaust volumes within, and a passage hole (8) situated on the rear wall (7) that allows the circulating fluid to be delivered to the valve plate (5).
  • the suction muffler (6) comprises a muffler head (9) that extends from outside the cylinder head (3) without touching it, aligning with the suction hole (4) covered by the rear wall (7), advancing to the rear wall (7) perpendicularly on the level of the suction hole (4), passing through the passage hole (8) and being seated around the suction hole (4) on the valve plate (5), having a cylindrical shape in the portion that is within the cylinder head (3).
  • the muffler head (9) provides the circulating fluid to flow a considerable amount of the distance from the suction muffler (6) to the valve plate (5) without contacting the cylinder head (3) and thus heat transfer to the circulating fluid is being reduced.
  • the muffler head (9) has a J shape.
  • One arm of the J shape forms the portion fixed to the cylinder and extending out from the cylinder head (3).
  • the elbow part of the J shape is aligned with the suction hole (4) covered by the cylinder head (3) and is outside the cylinder head (3).
  • the other arm of the J shape having a cylindrical shape, passes through the passage hole (8) and extends from the elbow to the valve plate (5).
  • the muffler head (9), passing through the passage hole (8) extends to the valve plate (5) and the ring shaped surface (Y) at its end presses on around the suction hole (4) and is seated on the valve plate (5). Accordingly the leakage of the circulating fluid is prevented. Since the muffler head (9) extends to the valve plate (5) perpendicularly, only the ring shaped surface (Y) at its end contacts the valve plate (5) and heat transfer from the valve plate (5) to the circulating fluid is reduced.
  • the passage hole (8) provides housing of the muffler head (9) and the muffler head
  • the passage hole (8) opens opposite the suction hole (4) so that the outlet orifice of the muffler head (9) is aligned with the suction hole (4) on the valve plate (5).
  • the cylinder head (3) comprises one or more recesses (10), situated around the passage hole (8) reducing the surface area of the walls of the passage hole (8) contacting the muffler head (9).
  • the muffler head (9) When the muffler head (9) is housed by passing through the passage hole (8), it contacts only the walls of the passage hole (8) between the recesses (10) and the heat transfer between the cylinder head (3) and the muffler head (9) is reduced.
  • the muffler head (9) comprises one or more assembly protrusions (11) situated around it that enable it to be fitted in the passage hole (8) by passing through the recesses (10) and one or more pins (12) situated on the assembly protrusions (11) providing the muffler head (9) to be fixed to the rear wall (7).
  • the cylinder head (3) comprises one or more pin sockets (13) situated on the inner surface of the rear wall (7), providing the pins (12) to be firmly fitted inside and the muffler head (9) to be undisplacably fixed on the rear wall (7).
  • the recesses (10) situated around the passage hole (8) of the cylinder head (3) also provide the assembly protrusions (11) to be inserted inside when the muffler head (9) is being mounted.
  • a better leak-proofing is provided between the ring-like surface (Y) at the end of the muffler head (9) and the valve plate (5), and leakage of the circulating fluid is prevented since the muffler head (9) is fixed to the cylinder head (3) by means of the pins (12) and the pin sockets (13) on the inner surface of the rear wall (7) so that it can't be displaced towards the rear.
