1. A pump, comprising:
- a frame adapted to rotate;
an arcuate chamber formed in said frame;
a piston adapted for reciprocal movement for exerting a pumping action whenever said piston is reciprocated, said piston at least partially extending into said chamber; and
a mass disposed in said chamber and coupled to said piston, responsive to rotation of said frame, for causing reciprocal movement of said piston, said mass freely movable within said chamber and disconnected from said piston but shiftable in an arcuate path along said chamber in response to rotation of said frame for causing reciprocal movement of said piston by contact with said piston;
said chamber having a radius of curvature and positioned in said frame so that rotation of said frame at any rotational speed results in a locally rotating gravity vector acting on said mass and causing a resonant oscillation of said mass in said chamber, said radius of curvature being adjusted to rotation of said frame such that the resonant oscillation frequency matches the rotation oscillation frequency of a device in which said pump is positioned for all rotational frequencies of interest.

Abstract
Disclosed is a tuned resonant oscillating mass pump, and particularly a pump structure and assembly which can be conveniently and readily mounted inside automotive tires for the purposes of maintaining optimum tire pressure and generating of electrical power from the movement of the tuned oscillating mass in such pumps. The oscillating mass can be a pendulum or a freely moving weight or a ball rolling within an arcuate chamber.

12. A pump, comprising:
-
a frame adapted to rotate; an arcuate chamber formed in said frame; a bellows coupled to said chamber for exerting a pumping action whenever said bellows is actuated; and a mass disposed in said chamber, said mass freely movable within said chamber along an arcuate path in said chamber to actuate said bellows in response to rotation of said frame; said chamber having a radius of curvature and positioned in said frame so that rotation of said frame at any rotational speed results in a locally rotating gravity vector acting on said mass and causing a resonant oscillation of said mass in said chamber, said radius of curvature being adjusted to rotation of said frame such that the resonant oscillation frequency matches the rotation oscillation frequency of said frame. - View Dependent Claims (13)
