Definitions

  • the present invention relates to a compressor comprising a cylinder head whose sealing member thrust surface is contracted.
  • suction mufflers are used enabling the circulating fluid used for providing cooling to reach the cylinder region without heating up, and the noise caused by the cycling fluid to be prevented.
  • a suction muffler is made of plastic material and is placed on the cylinder head or between the cylinder head and the valve plate. The sucked cycling fluid reaches the cylinder by passing through the portion forming the suction pipe, and the suction muffler provided in the cylinder head. While attempting to minimize the noise generated during this process, it is also required to improve the thermodynamic efficiency. However, heat transfer occurs at the portions where the cylinder head joins the suction muffler head, affecting the thermodynamic cycle.
  • the cylinder head thrusts the face surface of the body via a sealing member, and the thrust is applied from the edges of the face surface of the body which is distant from the body cylinder hole whose surface is a high-pressure zone. While the thrust force applied by the bolts is constant, the thrust pressure decreases on the thrust region enlarged due to being on the sides. Another problem experienced is the thrust being decreased due to the deformations forming on the cylinder head generating the thrust. The decreasing thrust causes the high-pressure gas to leak, leading to a decrease in efficiency.
  • EP 195 486 discloses a compressor in which heat transfer between a suction muffler and a cylinder head is minimized by contracting the contact surface in between.
  • the aim of the present invention is to realize a compressor with increased volumetric efficiency enabling a cycling fluid to be transferred to a cylinder without increasing its temperature and pressure by preventing thrust pressure decreases at the portions where the cylinder head and the cylinder hole contact each other.
  • the compressor realized to achieve the aim of the present invention and disclosed in the first claim and the dependent claims, comprises a sealing member placed such that its thrust surface is on the periphery of cylinder hole, and a cylinder head placed on the sealing member.
  • the thrust surface and the sealing member are contracted so as to be around the cylinder hole where the pressure is high.
  • the thrust surface is contracted it would be more durable, preventing thrust pressure decreases due to deformation.
  • a clearance is provided between the brackets extending outwards from the cylinder head, and the cylinder head resting on the body cylinder hole.
  • the brackets are spaced from the face surface plane so as not to contact the face surface.
  • brackets are provided in the preferred embodiment, placed around the portion of the cylinder head resting on the cylinder hole such that there is a given angle in between the brackets.
  • At least two pins are provided, placed opposite each other so as to be between two brackets.
  • the pins are used to reference to each other and group the cylinder head and the face surface.
  • the compressor of the invention comprises an exhaust connection slot provided on the cylinder head, enabling connection to the exhaust hole, and a protrusion disposed on each one of the valve plate and the sealing member, so as to be conformed with the shape of the exhaust connection slot and provide sealing.
  • Figure 1 is a schematic view of a compressor.
  • Figure 2 is a perspective view of the body, the suction muffler and the cylinder head assembled together.
  • Figure 3 is an exploded view of the body, crank, suction muffler, cylinder head and the sealing member.
  • Figure 4 is a frontal perspective view of the cylinder head.

  • the circulating fluid in the cylinder hole (7) is compressed by the rotational motion of the engine (4).
  • the circulating fluid enters the cylinder hole (7) by opening of the suction valve leaf (12) provided on the valve plate (11), and is compressed.
  • the circulating fluid is transmitted to the cylinder head (10) by opening of the exhaust valve leaf (13).
  • the cylinder head (10) thrusts on the valve plate (11), and the valve plate (11) in turn thrusts on the sealing member (14) thereby providing sealing between itself and the face surface (9).
  • the thrust surface is reduced so as to be only around the cylinder hole (7) where the pressure is high.
  • the thrust surface since the thrust surface is contracted, it would be more durable, preventing the decreases in thrust pressure due to deformation.
