  • Publication number: 20230057129
    Abstract: The present invention reveals an alternative compressor head arrangement capable of eliminating the occurrence of friction wear in the bending areas of the operation valves. For this, an interface blade arranged between the valve blade and the stop blade is used, so that the interface between the static end of the operation valve of the valve blade and the valve stop of the stop blade is fully carried out by the interface blade.

  • Patent number: 10174756
    Abstract: The present relation relates to the technological field of compressors. Problem to be solved: The current reciprocating compressors valves arrangements includes valves whose flexion area suffer from direct interference of the body disposed immediately over said valve. Such feature, besides damaging de valve movement, further causes wear phenomena on the flexion areas of the valve, which can result in critical fault of the valve and consequently of the compressor. Resolution of the problem: It is revealed a valve arrange whose end valve capable of moving includes a flexion area previously defined and intentionally misaligned with any contact area of the body immediately disposed over the valve.

  • Patent number: 9732741
    Abstract: The present utility model application refers to a new constructive arrangement introduced in acoustic filter of hermetic compressor, and more particularly, a new constructive arrangement that optimizes the suction flow of the acoustic filter, which is normally arranged within the hermetic housing of the hermetic compressor. The suction acoustic filter (1) is composed by at least one outlet pipe (2), outlet pipe (2) comprising at least two independent suction outlets (21). Each independent suction outlet (21) extending along outlet pipe (2).

  • Patent number: 9145879
    Abstract: The present invention refers to an acoustic filter for reciprocating compressor and, in special, a suction acoustic filter containing at least one inlet pipeline (21), at least one outlet pipeline (22), and at least one intermediate pipeline (42). Said acoustic filter (1) comprises at least two horizontal chambers (5, 6), wherein said chambers are interconnected by an intermediate pipeline (42), which has a superior portion (421) with a length that is equivalent to approximately 75% to 98% of the height of the first horizontal chamber (5) and an inferior portion (422) with a length that is equivalent to approximately 45% to 80% of the height of the second horizontal chamber (6).

  • Publication number: 20140345713
    Abstract: The present invention refers to a suction valve assembly for alternative compressors. Said suction valve assembly comprises at least two suction valves (3) independent from one another and disposed at one same blade (1), wherein each of said suction valves (3) comprises a functional edge (4) intended for a sole suction orifice (21) of the valve plate. Said suction valves (3) are separated from one another by at least one through slit (13).
