Abstract:
A dual rocking piston pump which includes a first piston with a first connecting rod eccentrically mounted to a rotor shaft and a second piston with a second connecting rod eccentrically mounted to the rotor shaft. The rotor shaft passes through a first bearing and a second bearing before being connected to a rotor body. The rotor body is disposed within a stator. The first and second bearings and stator are supported by a bracket. The bracket includes a hub which, in turn includes a first end connected to a wall at an opening in the wall. The hub also includes a second end. The first end of the hub supports the first bearing at the wall and the second end of the hub supports the second bearing. Both the first and second bearings are disposed in front of the motor or in front of both the rotor and stator. Because support for the rotor is provided entirely in front of the motor, no rear bell housing is required and because a single bracket supports the bearings, rotor and stator, fewer parts are required thereby making the pump lighter and more compact.
