Abstract

COMPRESSOR COM DESLOCAMENTO VOLUMéTRICO VARIáVEL. Um compressor com deslocamento volumétrico variável é revelado, o qual extrai fluído refrigerante de uma zona de pressão de aspiração e descarrega este fluido para uma zona de pressão de descarga, controlando o deslocamento volumétrico de acordo com a pressão em uma câmara de pressão de controle. O compressor possui um corpo de ressaltos, pistões, um conduto de alimentação, um conduto de liberação e uma válvula liga-desliga. O ângulo de inclinação do corpo de ressaltos pode ser modificado de acordo com a pressão da câmara de controle de pressão. Conforme o corpo de ressaltos gira, o pistão realiza um movimento alternativo dentro do cilindro. O conduto de alimentação fornece fluído refrigerante da zona de pressão de descarga para a câmara de controle de pressão. O conduto de liberação descarrega o fluído refrigerante da câmara de controle de pressão para a zona de pressão de aspiração. A válvula liga-desliga seletivamente abre e fecha o conduto de liberação em resposta às mudanças da temperatura. A válvula liga-desUga fecha o conduto de liberação quando a temperatura for igual ou maior do que uma temperatura pré-determinada.
