Abstract

Un resorte de placa, (6), que tiene una sección transversal en forma de gancho desde su parte inferior, es instalado en una vecindad de un extremo "b" de una placa de refrigeración por choque, (4). Uno de los extremos, "c" en el lado inferior está fijado a un nervio (1b) mediante soldadura, mientras que el otro extremo "b" en el lado superior está libre, lo cual le hace contactar estrechamente la vecindad del otro extremo "b" de la placa de refrigeración por choque, (4), gracias a su fuerza elástica. Esta condición hace que sea posible sellar un huelgo formado entre la placa de refrigeración por choque, (4), y la pieza de transición, (1), en el lado de un nervio, (1d), con lo cual se impide que las tensiones térmicas generadas en el nervio (1d), por ejemplo, afecten la placa de refrigeración por choque, (4).
