ANORDNING FOR REGLERING AV STROMNINGEN OCH MENGDEN AV ETT VETSKEFLODE, SAMT FORFARANDE FOR DESS MONTERING I EN CIRKULATIONSPUMP AV TVILLINGTYP

摘要

The device is situated at the intersection of four channels serving the intake area (2), delivery (3) area and the two shells (4 and 4'). It includes two valves (8, 9) mounted freely on a shaft (20) integral with a rotating member (10) and with a control button external to the pump body. The valves whose position depends on the pressure applied counter to a spring (23) provide the alternation in the flow coming from the active shell, in transit to the delivery side. The position of the rotating element controls the intake-delivery link and performs the function of flow rate regulator by common adjustment on the two pumps. The device is applicable to twin pumps, especially acceleration pumps for central heating.
