Definitions

  • the present invention refers to a new constructive disposition in reciprocating compressor suction valve and, specially, high performance reed valve used in reciprocating compressors which integrate cooling systems.
  • the suction valve here revealed comprises several constructive-dimensional features that makes possible its adequacy to reduced dimensions reciprocating compressors.
  • suction valves like reed are highlighted which are defined by a metallic foil whose general outline is analogous to the geometry of plate-valve that composes the reciprocating compressor head.
  • the figure 1 shows a suction valve like reed that, defined in a metallic foil of analogous general outline to plate-valve (not showed), integrates the current state of the art.
  • said metallic foil comprises a fundamentally continuous and regular area and a semi-outlining hollow slot whose form defines the flexible segment of suction valve.
  • Said suction valve showed on figure 1 is cooperating, at least, with a plate-valve described and shown on document US7083400 .
  • the suction valve shown on figure 1 includes at least one sealing end (related to the suction port on the plate-valve), at least one elastic flexion area and at least one passing port disposed between said sealing end and the elastic flexion area, port which is sized to be aligned with the exhaust port existing on the plate-valve.
  • the main objective of this constructive arrangement type of suction valve is optimizing the assembly process and suction valve alignment (in this case, the sealing end, the suction port and the passing port) with the plate-valve.
  • the new constructive arrangement introduced in suction valve of reciprocating compressor comprises a rigid foil 1, preferably made with a metallic alloy, in which it is observed a semi-outlying hollowed slot 2 that defines the flexible segment 3, which includes at least one sealing end 31, at least one elastic flexion area 32, at least one passing port 33, and at least one crimping area 34.
  • Said rigid foil 1 comprises still at least four passing ports 11 that, disposed in disconnection with the semi-outlying hollowed slot 2 and the flexible segment 3, define just mounting orientation guides for the fixing means (not shown) used to fix the reciprocating compressor head.
  • the "H” dimension comprises the general longitudinal length of the flexible segment 3, this is, the straight length measured between the distal points of the sealing end 31 and the crimping area 34 of flexible segment 3.
  • the “L” dimension comprises the general latitudinal length of the flexible segment 3, this is, the straight length measured between the distal points of the sealing end 31 of flexible segment 3.
  • the "C” dimension comprises the general longitudinal length of the passing port 33 of flexible segment 3, this is, the straight length measured between the oppose distal points of passing port 33 of flexible segment 3.
  • the "C” dimension, including the relation of this with the "H” dimension is better shown on figure 3B .
  • the "R1" dimension comprises the upper internal outline radius of passing port 33 of flexible segment 3, and the dimension “R2" comprises the lower internal outline radius of passing port 33 of the flexible segment 3.
  • said passing port 33 of flexible segment 3 comprises an essentially oblong format.
  • the dimensions “R1” and “R2”, as well as the imaginary circles “CR1” and “CR2” respectively related to “R1” and “R2” radius are better shown on figure 3C .
  • the “B1" dimension comprises the latitudinal straight distance between two points, to know: point I (insertion point between the imaginary circle “CR1” and the most prominently portion of the upper internal outline radius of passing port 33 of flexible segment 3), and point II (external outline point of flexible segment 3 closer to point I).
  • the dimension “B2” comprises the latitudinal straight distance between two points, to know: point I (insertion point between the imaginary circle “CR2” and the most prominently portion of the lower internal outline radius of passing port 33 of flexible segment 3), and point II (external outline point of flexible segment 3 closer to point I).
  • the ratio between the above mentioned dimensions enables the rigidity increase and of natural frequency of flexible segment 3 without being necessary any change on material or thickness of rigid foil 1.
  • the operation frequency point of flexible segment is different from the natural frequency of internal resonant cavity of compressor (the internal cavity of compressor comprises the region composed by cooling gas located between the compressor body and the internal pieces of the compressor).
  • the objective of changing the natural frequency of the valve is leaving the excitation region of natural frequency of compressor cavity, further to guarantee cooling capability parameters and energetic performance desired of the product.
