Abstract

"COMPRESSOR HERMéTICO". Uma câmara de alta pressão (23) em um invólucro (20) se comunica no fundo da mesma com um retentor de líquido (31). Uma tubulação de comunicação (34) é conectada a uma extremidade do mesmo à extremidade superior do retentor de líquido (31) e conectada, em sua outra extremidade, a um tubulação de entrada (28). Um recipiente de gás (35) e primeira e segunda válvulas solenóides (36, 37) são dispostos na tubulação de comunicação (34). Quando a primeira válvula solenóide (36) é fechada e a segunda válvula solenóide (37) é aberta, o recipiente de gás (35) se comunica com a tubulação de entrada (28) para reduzir a pressão no recipiente de gás (35). Em seguida, quando a primeira válvula solenóide (36) é aberta, e a segunda válvula solenóide (37) é fechada, o recipiente de gás (35) se comunica com o retentor de líquido (31) para reduzir a pressão no retentor de líquido (31). Então a pressão do óleo lubrificante no retentor de líquido (31) é baixada para gaseificar um refrigerante que é dissolvido fio óleo lubrificante. Como resultado, o mau funcionamento da lubrificação causado devido à diminuição da viscosidade do óleo lubrificante pela dissolução do refrigerante no mesmo é evitado e a confiabilidade do compressor hermético é aumentada.
