Fundamentos da InvencaoFoundations of the Invention
Um compressor tem como fungao elevar a pressao de determinado volume de flui- do a uma pressao necessaria a realizagao de um ciclo de refrigera?ao. Sao conhecidos da tecnica os chamados compressores alternatives, onde um pistao desliza reciprocantemente no interior de um cilindro para realizar a compressao dos gases. Nos compressores Iinea- res, ο deslocamento do pistao e provocado por um motor linear.A compressor has the function of raising the pressure of a given volume of fluid to a pressure necessary to perform a refrigeration cycle. So-called alternative compressors are known in the art, where a piston slides reciprocally within a cylinder to perform gas compression. In Inline compressors, the displacement of the piston is caused by a linear motor.
As partes que comp5e ο compressor linear sao alojadas dentro de uma carcaga hermeticamente fechada, exceto por orificios de entrada e saida de gases. A vedagao e necessaria uma vez que os gases nao comprimidos circulam entre a caraga e as pegas do compressor.The parts that make up the linear compressor are housed inside a hermetically sealed shell except for gas inlet and outlet ports. Sealing is necessary since uncompressed gases circulate between the carrier and the compressor handles.
Alem de servir como alojamento .para as partes componentes do compressor, a carcaga tambem tem a fungao de isolar ο ruido ocasionado pelas partes moveis e prover uma certa resistencia estruluraJLao conjunto.In addition to serving as a housing for the compressor component parts, the shell also has the function of isolating the noise caused by the moving parts and providing some resistance to the joint structure.
As carca?as de compressores lineares sao convencionalmente cilindricas, de modo a garantir um correto alinhamento entre as pegas, e manter um conjunto compacto e ο mais Ieve possivel.Linear compressor housings are conventionally cylindrical in order to ensure correct alignment between the handles, and to maintain a compact and lightweight set possible.
Entretanto, as carcagas conhecidas ainda possuem uma dimensao excessivamente gran.de’（^-.ΓηοοΙοιιιβ-ηδο-ροϋΙθηυβΓ-ι^Ηζθο^δ.βηυρΙίχ^ςδθε.ςΛϋβ.χίοίΓ^.ιτι um compressor de tamanho reduzido.However, the known carcasses still have an excessively large size.
