Abstract
Apparatus for harnessing and utilizing, inter alia, cyclic forces generated at a location eccentric from the axis of rotation of a rolling wheel. The apparatus may include, for example, pumps that can be attached to the valve stem of an automobile wheel in order to pressurize under-inflated tires and maintain tire pressure at a preset value.
Claims34
Apparatus for utilizing a cyclic resultant force of a centrifugal force and a gravitation force, said apparatus including:
- a vehicle wheel including a pneumatic tire;
- pump means including a piston reciprocal in a cylinder in response to the cyclically changing resultant force of centrifugal and gravitational forces acting on said piston for pressurizing air to inflate said pneumatic tire, said piston being acted upon by an air cushion for providing a restoring force;
- and
- attachment means at a site eccentric to the axis of rotation of said vehicle wheel for support of said pump means by said vehicle wheel externally of the pneumatic tire.

Apparatus for pressurizing a pneumatic tire, said apparatus including:
- a vehicle wheel including a pneumatic tire;
- attachment means at a site eccentric to the axis of rotation of said vehicle wheel for enabling the utilization of a cyclic occurring resultant force of centrifugal and gravitation forces;
- and
- pump means including a piston reciprocal in a cylinder while supported by said attachment means for pressurizing air to inflate said pneumatic tire in response to the cyclically changing force acting on said piston, said piston being acted upon by an air cushion to provide a restoring force.
