APPARECCHIATURA PER LA REGOLAZIONE DELLA PORTATA DI COMPRESSORI ROTATIVI. |
摘要 |
<p>A device for regulating the delivery of rotary compressors, such as screw-type compressors with oil injection, comprises a regulating valve for varying the cross-sectional area of a suction pipe and a non-return valve which closes said suction pipe. The two valves are disposed one behind the other in the flow direction within a casing incorporating a suction pipe. In order to provide a low resistance to flow and to simplify the construction, both valves are in the form of flap valves with the flap of the non-return valve arranged to close a valve seat provided in the casing and being pivotable against a resetting force about an axis extending outside the cross-sectional area of the valve seat.</p> |
