Abstract

Valvola per un compressore per refrigerazione ermetico o stagno, del tipo alternativo, comprendente un blocco cilindro (10) e alloggiante un pistone (20) mobile di moto alternativo; una piastra valvolare (30) con una faccia frontale (30a) ed una faccia posteriore (30b) fissata al blocco cilindro (10) e dotata di almeno una coppia di orifizi per gas assiali (31, 32) ponenti in comunicazione l'interno del cilindro (c) con la faccia anteriore (30a) della piastra valvolare (30) attraverso una valvola a pettine rispettiva che è fissata alla faccia della piastra valvolare verso la quale è aperta una estremità di uscita (31b, 32b) del rispettivo orifizio (31, 32) del gas e comprendente un elemento a lama (60, 80). Ciascuna valvola comprende inoltre mezzi di sollecitazione (70, 90) disposti tra l'elemento a lama (60, 80) e la piastra valvolare (30) per spostare detto elemento a lama ad una posizione di apertura parziale della valvola non appena una condizione di equilibrio di pressione si verifica tra le regioni a monte e a valle della valvola, detti mezzi di sollecitazione (70, 90) essendo elasticamente deformati dall'elemento a lama (60, 80) quando la valvola si chiude, ogni qualvolta la pressione del gas a valle della valvola supera la pressione del gas a monte di essa.
