  • this support arrangement is, such as the technical solution described in patent document JP 3722149, of the type supporting the hermetic housing 1 of a reciprocating compressor on an accommodation surface 4 of a refrigeration equipment (not particularly illustrated).
  • the reciprocating compressor of the present invention may be each and every compressor composed of functional elements and systems widely known to those skilled in the art. In this context, it is thus noticed that the compression mechanism (not shown), the electric motor (not shown) and other traditional components that make part of a reciprocating compressor are enclosed within the hermetic housing 1.
  • the refrigeration equipment of the present invention may be each and every refrigeration equipment composed of a condenser, an evaporator, a refrigerant expansion valve (or capillary tube), a reciprocating compressor, a thermal chamber and a space for accommodating the reciprocating compressor.
  • Figures 1 to 10 illustrate the preferred embodiment of the invention in question.
  • the support arrangement is essentially composed of two base plates 2, and four damping elements 3, which are arranged on the accommodation surface 4 of the refrigeration equipment (not particularly illustrated).
  • At least one damping element 3 is provided, which is capable of being arranged on the accommodation surface 4 of the refrigeration equipment, said damping element 3 comprising at least one upper support surface 31;
  • said base plate comprises at least one support surface 21 and at least one coupling surface 22; the support surface 21 being supported by the upper support surface 31 of the damping element 3 and at least one anchoring point 11 disposed in the lower region of the housing 1 of the housing being coupled to the coupling surface 22 of the base plate 2
  • each coupling surface 22 comprises a contact point 24 adapted to be fixed to an anchoring point 11 of the hermetic housing 1 of the reciprocating compressor.
  • the support surface 21 comprises at least one hole 23 (in this example, two holes 23) capable of receiving a damping element 3 that will be detailed below in the text.
  • Figures 4, 5 and 6 show a second possible configuration for the base plate 2.
  • the coupling surface 22 is defined as a “breaking point” on the base plate 2; in other words, the coupling surface 22 in the second configuration does not define an extension or extension region.
  • Such a configuration is especially advantageous as it makes the base plate compact and lightweight.
  • the coupling surface 22 is defined as a substantially square-shaped extension and provided with an opening 25, wherein the coupling surface 22, as proposed herein, is for coupling to a protective support 12 of the housing 1 of the reciprocating compressor.
  • Said protective support 12 is also commonly known to those skilled in the art as fence.
  • protective support 12 is a metal support for the protection of electrical parts externally positioned in the housing 1 of the compressor, and it is usually fixed around the hermetic terminal.
  • electrical components and thermal protectors can also be attached.
  • the coupling surface 22 defines an extension towards the base of the housing 1, that is, towards the accommodation surface 4.
  • the coupling surface 22 defines an extension towards the upper part of the housing 1, that is, opposite the accommodation surface 4.
  • the coupling surface 22 is preferably positioned at the opposite end to the hole 23.
  • any of the three configurations presently proposed may be used in combination and/or together.
  • the coupling surface 22 defines an angle “cp” with the support surface 21.
  • the angle “cp” has 90°, that is, the coupling surface 22 is positioned perpendicular to the support surface 21. It is noteworthy that there may be slight variations in the angle “cp”. More specifically, when mounting the arrangement, the support surface 21 will be parallel to the accommodation surface 4 and the coupling surface 22 will be parallel to the longitudinal axis of the housing 1, which results in stability for the assembly and aids in the absorption of normal vibrations of compressor operation by damping elements 3.
  • the support surface 21 defines a single and continuous plane, that is, the support surface
  • the base plates 2 are made of metallic material by means of the mechanical stamping process.
  • the base plates 2 could be made of polymer by known industrial processes.
  • the damping element 3 is made of flexible material, since it aims to absorb/cancel the vibrations of the compressor operation.
  • the support surface 22 receives the lower region of the housing 1 of the compressor and there may be at least one contact point 24 (see Figure 3) capable of supporting the housing 1.
  • This contact point 24 defines an attachment point, preferably by welding.
  • the contact point 24 is created to generate a preferred contact region where there will be adhesion by spot welding.
  • the contact point 24 may be located lower, near the accommodation surface 4 of the compressor, or it may be located higher, near the support surface 21.
  • Such a change of configuration, for sure, will vary the positioning height of the housing and this is only possible because the base plate 2 comprises at least one inclined surface 22.
  • the arrangement for supporting compressor in a refrigeration equipment can be applied in different designs and conditions, since the distance between the lower level and the upper level of attachment of the compressor housing is not always fixed, being adjustable by varying the location of the contact point 24.
  • each damping element 3 comprises a body 33, preferably cylindrical and hollow, but which may not restrictively be of other geometrical shapes and be solid. Furthermore, it is noticed that the damping element 3 comprises two surfaces, at least one lower support surface 32 and one upper support surface 31. It is further noticed that the damping element 3 comprises a constricted region 34 which, as the name suggests, has a diameter smaller than the body 33 of the damping element 3. Finally, there is a circular extension 35, which is arranged over the constricted region 34.
  • the constricted region has a diameter smaller than the body 33, however, the circular extension 35 has an intermediate diameter to these two, being larger than that of the constricted region 34 and smaller than that of the body 33.
  • Such a configuration is of particular importance for understanding the mounting of the base plate 2 on the damping element 3.
  • the base plate 2 comprises a support surface 21 adapted to receive the damping element 3; more specifically, as can be seen from Figures 3, 6 and 9, the hole 23 is developed to be juxtaposed to the constricted region 34 so that the support surface 21 rests on the upper support surface 31.
  • the diameter of the hole 23 in the support surface 21 is substantially equal to the diameter of the constricted region 34.
  • the diameter of the hole 23 is substantially smaller than the diameter of the circular extension 35.
  • the circular extension 35 is made of flexible material, allowing its diameter to vary to be received by the hole 23 and/or - the circular extension 35 is detachable, allowing its removal to fit the base plate 2 and, later, its replacement to the original position.

Abstract

La présente invention concerne un agencement pour supporter un compresseur dans un équipement de réfrigération et, plus particulièrement, un agencement de support comprenant au moins un élément d'amortissement spécialement conçu pour fixer un compresseur alternatif dans un réfrigérateur. La présente invention est caractérisée par un agencement de support ayant un coût de fabrication plus faible, et est applicable à une large gamme de modèles de compresseurs et de réfrigérateurs. Ledit agencement pour supporter un compresseur dans un équipement de réfrigération permet également une meilleure commande et un meilleur dimensionnement du positionnement relatif entre la base de compresseur et le sommet de la surface de support de l'équipement de réfrigération, et il permet également, en raison de l'utilisation d'amortisseurs supérieurs et de géométries différentes, une commande d'amortissement en fonction du besoin de chaque projet d'application.
