RECURRENCE POWER GROUP OF A TERMINAL ENGINE RECURRENCE FLOW

摘要

A pump assembly (GP) for recirculating a cooling fluid of a heat engine, comprising a pump body (CT), an impeller (PW) carried by a driven shaft (SH), adapted to be associated with a cooling circuit of the heat engine; a pulley (PL) adapted to be dragged into rotation by the heat engine, a first friction reversible clutch (C1), adapted to connect/disconnect said pulley to/from said driven shaft (SH), an electric motor (EM) associated with said driven shaft (SH) for guiding the impeller (PW) into rotation, a planetary gear train (EPC) having an inlet (R) operatively associated with said electric motor (EM), a first outlet (CR) associated with said driven shaft (SH) and a second outlet (RG) and a second friction reversible clutch (C2), independent of said first friction reversible clutch (C1) adapted to block said second outlet with respect to said pump body (CT).
