Abstract

COMPRESSOR DE REFRIGERANTE. Trata-se de um componente bidirecional atuado termicamente que inclui um elemento de aquecimento e material de cera fornecido em um alojamento anexado, em que o elemento de aquecimento é ativado para derreter a cera, que se expande para causar movimento do alojamento ou de um elemento montado no mesmo. Quando o elemento de aquecimento é desativado, a cera endurece e se constringe para permitir o movimento na direção oposta, com base na aplicação de uma força na direção oposta, que pode ser fornecida por uma mola de propensão ou um segundo atuador. Um dispositivo médico ajustável pode incluir o componente atuado termicamente para controlar o ajuste do dispositivo.
