Abstract

Si descrive una disposizione di valvole di ammissione e di scarico di aria compresse per macchine formatrici, particolarmente macchine spara-anime, in cui nella unità di sparo consistente di un serbatoio di pressione e di uno stantuffo di comando, al disotto dello stantuffo di comando, è disposta una camera di pressione, la quale presente almeno due aperture. Ad una apertura è collegata una valvola di sfiato rapido. L'altra apertura si trova in collegamento con la camera di sparo attraverso un canale ed è ricoperta mediante un elemento di tenuta. L'elemento di tenuta consiste di un materiale resistente all'abrasione, è formato a guisa di labbro ed aderisce, nell'interno della camera di pressione, a questa apertura.An arrangement of compressed air admission and discharge valves for forming machines, particularly core-firing machines, is disclosed wherein in the firing unit consisting of a pressure tank and a control plunger, below the control plunger, a pressure chamber is arranged, which has at least two openings. A quick release valve is connected to an opening. The other opening is connected to the firing chamber through a channel and is covered by a sealing element. The sealing element consists of an abrasion-resistant material, is formed in the form of a lip and adheres, inside the pressure chamber, to this opening.
