Document Type and Number:
Japanese Patent JP4829957
Kind Code:
B2
Abstract:
An intended purpose of this invention is to realize a gear pump suitable for delivery of high-pressure and high-viscosity fluids by using helical gears 2 and 3 meshing with each other. For this purpose, the gear pump includes introduction paths 121 and 131 for introducing the fluid from a discharge side toward shaft end sides of gear shafts 21 and 31 to apply shaft ends of the gear shafts 21 and 31 with fluid pressures counterbalancing axial thrusts produced by the helical gears 2 and 3.
