PUMP

PURPOSE: A pump is provided to control a slide valve effectively by using inside fluid pressures of a peripheral pump. CONSTITUTION: A pump comprises a pump shaft(2), a controllable slid valve(4), a displacement pump(6), a peripheral pump, and a valve device(7). An impeller(3) is arranged in the pum...

Beschreibung
Zusammenfassung:	PURPOSE: A pump is provided to control a slide valve effectively by using inside fluid pressures of a peripheral pump. CONSTITUTION: A pump comprises a pump shaft(2), a controllable slid valve(4), a displacement pump(6), a peripheral pump, and a valve device(7). An impeller(3) is arranged in the pump shaft. The controllable slide valve controls delivery speed of the pump and slides over the impellers. The displacement pump and the peripheral pump are arranged in the pump shaft. The displacement pump and the peripheral pump generate fluid pressures, which control the slide valve. The valve device controls the fluid pressure generated from a second pump with connecting or separating a pressure side and a suction side of the displacement pump and the peripheral pump each other.
