SYSTEM FOR RECOVERING OR CONVERTING ENERGY FOR EQUIPMENT HAVING A MOVABLE IMPLEMENT AND METHOD
First Claim
1. A system for recovering or converting energy associated with a machine having an implement mounted on the machine by an implement supporting member, wherein the implement supporting member is movable relative the machine by an hydraulic actuator, the system comprising:
- an energy converter mounted on one of the implement supporting member or the machine;
an energy converter activation device interposed between the energy converter and the other of the machine and the implement supporting member; and
a flywheel mounted on the same implement supporting member or machine as the energy converter, the flywheel being interposed between the energy converter activation device and the energy converter;
wherein relative movement between the energy converter activation device and the flywheel drives the flywheel, which in turn drives the energy converter.

Abstract
Potential energy of an implement and implement supporting member, such as a mechanical arm, attached to a machine, such as construction equipment, is recovered by an energy converter, such as a flywheel or a pull-cord generator, during relative movement between the implement supporting member and the machine. An activator causes relative movement between the implement and the machine. The flywheel or pull-cord generator drives an auxiliary pump or electric generator when the flywheel or pull-cord generator moves relative the auxiliary pump or electric generator. The recovered potential energy is stored in an accumulator or battery. Kinetic energy may be converted to electric energy or hydraulic pressure and stored for later use.

12. A system for recovering or converting energy associated with a machine having an implement mounted on the machine by a first mechanical arm and a second mechanical arm interposed between the first mechanical arm and the machine, wherein the first mechanical arm is movable relative the second mechanical arm about a pivot point by a linear actuator, one end of the linear actuator being secured to the first mechanical arm on one side of the pivot point and the opposite end of the linear actuator being secured to the second mechanical arm on the other side of the pivot point, the system comprising:
-
an energy converter mounted on one of the first and second mechanical arms on one side of the pivot point; an energy converter activation device secured to the other of the first and second mechanical arms on the other side of the pivot point; and a flywheel mounted on the same mechanical arm as the energy converter, the flywheel being interposed between the energy converter activation device and the energy converter; wherein the energy converter activation device drives the flywheel as the linear actuator extends or retracts and the first mechanical arm moves relative to the second mechanical arm and wherein the flywheel drives the energy converter.

13. A method of recovering or converting energy associated with a machine having an implement mounted on the machine by an implement supporting member, wherein the implement supporting member moves relative the machine by an hydraulic actuator, wherein the machine comprises (a) an energy converter mounted on one of the implement supporting member or the machine (b) an energy converter activation device interposed between the energy converter and the other of the machine and the implement supporting member, and (c) a flywheel mounted on the same implement supporting member or machine as the energy converter, the flywheel being interposed between the energy converter activation device and the energy converter, the method comprising:
driving the flywheel by the energy converter activation device as the energy converter moves relative to flywheel and driving the energy converter by the flywheel. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
