Abstract

Un piccolo compressore frigorifero ermetico del tipo a singolo pistone alternativo ha una piastra valvolare piana catendentisi attraverso l'estremità aperta del cilindro, con un'apertura di scarico estendentesi attraverso la piastra valvolare fuori dalla linea centrale dell'alesaggio del cilindro. Il pistone ha una faccia terminale generalmente piana con una rientranza almeno parzialmente in allineamento con l'apertura di scarico, per consentire un flusso di gas migliorato verso l'apertura di scarico con un minore volume di gioco. Un'ulteriore riduzione del valore del gioco può essere ottenuto disponendo una spinta sporgente sulla faccia terminale del pistone in linea con l'apertura di scarico, per riempire parzialmente l'apertura di scarico nel centro superiore.
