Abstract
Una valvola d'espansione meccanica di un refrigerante dosa il flusso di refrigerante attraverso di essa in una direzione tramite un orifizio la cui area trasversale varia in funzione del differenziale di pressione attraverso la valvola. La stessa valvola controlla il flusso di refrigerante nell'altra direzione tramite un orifizio dosatore ad area fissa.
