Abstract

resumo válvula de assento oca é proposta uma válvula de assento oca (10) tendo uma capacidade de transferência de calor melhorada. a válvula tem uma cavidade interna (s), que se estende de dentro de uma cabeça de válvula (14) para dentro de uma haste (12) da válvula, é carregada com um refrigerante (19) juntamente com um gás inerte. o refrigerante na cabeça de válvula (14) é agitado por correntes de redemoinhos do refrigerante geradas durante os movimentos recíprocos da válvula. uma multiplicidade de saliências formadoras de redemoinhos é formada pelo menos em um do fundo e do teto da cavidade da cabeça da válvula (s1) de tal modo que as correntes de redemoinhos (f20, f30) de refrigerante são geradas pelas saliências na cavidade da cabeça de válvula (s1) durante os movimentos recíprocos da válvula para assim agitar o refrigerante na direção circunferencial da cavidade (s1).
