Abstract

Patente de Invenção:<B>"MáQUINA DE CALOR E DE FRIO"<D>. A invenção refere-se a uma máquina de calor e de frio que opera de acordo com um processo de circuito de gás regenerativo, com dois pistões em linhas móveis (8, 9) em uma carcaça vedada contra pressão (1) que definem em conjunto um volume de trabalho a quente (V~ w~) e sendo que um deles (8) limita um volume de trabalho a quente (V~ h~) para o qual é empregado o calor, e o outro (9) limita um volume de trabalho a frio (V~ k~), sendo que os três volumes de trabalho (V~ h~, V~ w~, V~ k~) estão interconectados por meio de regeneradores (R~ h~, R~ k~) e transmissores de calor (W~ w~, W~ k~). A fim de obter uma elevada eficiência na transferência de calor com uma construção compacta, o pistão (9) que separa os volumes de trabalho a quente do frio (V~ w~, V~ k~), por meio de seu fundo do pistão (9a), é conformado em forma de pote. O revestimento do pistão (9b) atua como um separador entre o transmissor de calor a quente (W~ w~) que fica externo, e o transmissor de calor a frio (W~ k~) que fica interno. Nos dois transmissores de calor (W~ w~, W~ k~) o calor é transferido entre as superfícies exterior e interior do revestimento do pistão (9b) e da superfície correspondente do respectivo transmissor de calor (W~ w~ ou W~ k~).
