Abstract
A pendulum pump includes a housing, a cover positioned on the housing and forming a cavity therebetween, an inner rotor and an outer rotor positioned within the cavity, wherein the inner rotor is connected via a plurality of pendulums to the outer rotor, and the pendulums are mounted to the outer rotor in an articulated manner such that a rotational eccentricity can be imparted between the inner rotor and the outer rotor to control a flow rate of the pendulum pump, and a protective plate positioned within the cavity and against a surface of one of the housing and the cover.

A method of fabricating a pendulum pump, comprising:
- positioning a cover on a housing and forming a cavity therebetween;
- positioning an inner rotor and an outer rotor within the cavity;
- connecting the inner rotor to the outer rotor via a plurality of pendulums;
- mounting the pendulums to the outer rotor in an articulated manner such that a rotational eccentricity can be imparted between the inner rotor and the outer rotor to control a flow rate of the pendulum pump;
- and
- positioning a protective plate within the cavity, through which no fluid passes, and stationarily against a surface of one of the housing and the cover.
A method of refurbishing a pendulum pump, comprising:
- disassembling a cover, a housing, an inner rotor, an outer rotor, and a plurality of pendulums of a pendulum pump;
- positioning the cover on the housing and forming a cavity therebetween;
- positioning the inner rotor and the outer rotor within the cavity;
- connecting the inner rotor to the outer rotor via the plurality of pendulums;
- mounting the pendulums to the outer rotor in an articulated manner such that a rotational eccentricity can be imparted between the inner rotor and the outer rotor to control a flow rate of the pendulum pump;
- and
- positioning a protective plate within the cavity, through which no fluid passes, so that it is stationary against a surface of one of the housing and the cover.
