ギヤポンプ
Document Type and Number:
Japanese Patent JP2005500456
Kind Code:
A
Abstract:
A gear pump, in particular for pumping material such as rubber mixes, includes an enclosure in which a central gear wheel and two peripheral gear wheels rotate. Teeth of the central gear wheel mesh with teeth of both peripheral gear wheels to pump material from an inlet to an outlet. The pump includes at least one feed chamber in which a feed mechanism delivers material to the inlet. The gear wheels are separately driven by a driving torque. A prestressing device applies a torsional prestress which presses the meshing teeth together for creating a seal between those meshing teeth to prevent leakage of material past the teeth.
