  • Patent number: 10711777
    Abstract: The present invention relates to the technological field of compressors and components and/or devices for compressors. Problem to be solved: The current state of the art includes cooling system of dual evaporation and/or dual suction. On the solutions already existing, the selection of one among the two evaporation/suction lines is done by high complexity constructive mechanisms. Problem resolution: The invention in question aims to simplify the construction of a selection mean of one among two evaporation/suction lines. For so, is revealed a suction acoustic filter for reciprocating compressor which integrates an automatic valve coupled to the inlet way of the suction acoustic filter and a valve of a way is coupled to the inlet way of the suction acoustic filter, being said automatic valve and said valve of a way acting selectively reciprocating, where the valve opening of a way ends up opening the automatic valve.

  • Patent number: 9109588
    Abstract: The block (B) comprises a piston hub having a horizontal axis (X) and housing a piston and a shaft hub housing a crankshaft and having a vertical axis (Y) intersecting the horizontal axis (X). The block (B) incorporates a connecting portion having a first end attached to a region of the piston hub disposed on a side of the horizontal axis (X) opposite to that turned to the shaft hub, and a second end attached to an adjacent end portion of the shaft hub. The connecting portion is elastically deformable by a resulting bending moment (MF) generated: by a first compression derived force (F1) actuating on the second end of the connecting portion; and by a second compression derived force (F2) applied to a free end portion of the shaft hub and which tends to provoke an angular displacement of the vertical axis (Y) of the shaft hub in the direction of the first compression derived force (F1).
