Abstract:

A magnetically engaged pump includes a pump housing with a rotatable magnetic drive assembly, a cylindrical canister and a rotatable driven magnet assembly. This magnetic coupling is associated with a pump rotor and a laterally positioned gear wheel to define a gear pump. This magnetic coupling is alternatively associated with a pump rotor with an impeller to define a centrifugal pump. Either pump includes a stationary shaft to mount the driven magnet assembly and pump rotor. A rotatable carrier with bushings and thrust bushings coaxially supports the rotatable driven magnet assembly and pump rotor.

International Classification:

F04B 9/04
F04B 43/04
F04B 17/03
F04B 19/22
F16H 37/12

Abstract:

A reciprocating pump and transmission assembly having a one-way clutch is disclosed. The transmission includes an input shaft with an eccentric element, a drive link rotatably connected at one end to the eccentric element and at the other to a driven arm. The driven arm is connected to a driven shaft via a one-way clutch. The oscillating motion of the eccentric drives the drive link and driven arm and the one-way clutch translates that motion into incremental motion of the driven shaft. By changing the stroke length of the drive link various gear ratios between the drive shaft and driven shaft are achieved. The driven shaft then uses a mechanism such as a Scotch Yoke to create reciprocating motion to drive one or more pumping elements.

Abstract:

The disclosure provides a gear pump rotor assembly that includes a rotor body, a rotor head having a plurality of gear teeth and being connected to the rotor body, at least one connector extending between the rotor body and the rotor head, at least one radial deformation control member that extends into at least one gear tooth of the rotor head and reduces the radial deformation of the rotor head relative to the rotor body when a change in temperature causes radial deformation of the rotor body and rotor head.
