20150034027 | HYBRID ELECTROMECHANICAL COOLANT PUMP - The invention relates to a coolant pump having an impeller which is arranged on a pump impeller shaft and having a drive device for the impeller, which drive device has a mechanical drive and an electric-motor drive. The impeller shaft is divided into a driving section and a driven section, and an openable and closable clutch is arranged between the driving section and the driven section. Operation of the coolant pump by either the mechanical drive or the electric-motor drive can be dependent upon a predetermined speed of threshold of rotation of the impeller, and/or upon a predetermined power usage threshold. | 02-05-2015 |
20150037177 | HYBRID ELECTROMECHANICAL COOLANT PUMP WITH BASE FLOW AND PEAK FLOW - The invention relates to a coolant pump having an impeller which is arranged on a pump impeller shaft and having a drive device for the impeller, which drive device has a mechanical drive and an electric-motor drive. The impeller shaft is divided into a driving section and a driven section, and an openable and closable clutch is arranged between the driving section and the driven section. | 02-05-2015 |
