Reciprocating compressor valves arrangement
View Patent ↗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.
1. Reciprocating compressor valves arrangement, comprising a main valve and a valve stop;
the main valve comprising a fixing end, a moving end, and a flexion area;
the valve stop comprising a fixing support area outlined by a crimping line end;
the beginning of the flexion area of the main valve being a transverse flexion line, and
the transverse flexion line of the flexion area of the main valve and the crimping line end of the fixing support area of the valve stop are longitudinally misaligned among them;
further comprising an auxiliary valve comprising a fixing end and a transverse flexion line, said auxiliary valve being disposed between the main valve and the valve stop, the fixing end of the main valve, and the fixing end of the auxiliary valve and the fixing support area of the valve stop are fixed one above each other;
characterized by the transverse flexion line of the main valve, the transverse flexion line of the auxiliary valve, and the crimping line end of the fixing support area of the valve stop are longitudinally misaligned to each other.
2. Reciprocating compressor valves arrangement, according to claim 1 , foreseen:
a third dimension related to a third extension between the beginning of the fixing end and the beginning of the flexion area of the main valve;
a second dimension related to a second extension between the beginning of the fixing end and the beginning of the flexion area of the auxiliary valve; and
a first dimension related to a first extension between the beginning of the fixing support area and the crimping line end of the valve stop,
the reciprocating compressor valves arrangement being characterized by the third dimension being larger than the first dimension, and the second dimension being larger than the first dimension and less than the third dimension.
3. Reciprocating compressor valves arrangement, according to claim 2 , characterized by:
the third dimension being from 1.2 to 2.5 times larger than the first dimension; and
the second dimension being 1.1 to 2.4 times larger than the first dimension, respecting that the second dimension should always be less than the third dimension.
