FLUID PUMP WITH SHAFT DRIVEN PUMPING ELEMENT |
| 摘要 |
In at least some implementations, a fluid pump includes a drive shaft including at least one drive surface and a pumping element. The pumping element includes an opening in which a portion of the drive shaft is received so that the pumping element is driven for rotation by the drive shaft, and the opening is larger than the drive shaft to provide a clearance between the pumping element and at least part of the drive shaft. The pumping element also includes at least one engagement surface arranged to be engaged by the drive surface of the drive shaft when the drive shaft is rotated where one or both of the drive surface and the engagement surface are angled to provide a surface area of engagement between the drive surface and engagement surface that is at least 1% of the surface area of the drive surface. |

1. A fluid pump, comprising:
a drive shaft driven for rotation and including at least one drive surface; a pumping element including an opening in which a portion of the drive shaft is received so that the pumping element is driven for rotation by the drive shaft, the opening being larger than the drive shaft to provide a clearance between the pumping element and at least part of the drive shaft, and the pumping element also including at least one engagement surface arranged to be engaged by the drive surface of the drive shaft when the drive shaft is rotated where one or both of the drive surface and the engagement surface are angled to provide a surface area of engagement between the drive surface and engagement surface that is at least 1% of the surface area of the drive surface. |
