A dual energy recovery, storage and use system comprising an electrically operated machine capable of regenerative electrical energy recovery, an electrically driven hydraulic regenerative energy recovery system which utilizes regenerative electrical energy to drive an electrically driven hydraulic pump/motor as a pump to pressurize hydraulic fluid in an accumulator, then uses the previously stored pressurized fluid to drive a hydraulic pump/motor as a motor to operate an electric motor/generator as a generator providing electricity to operate/assist in operating an electrically operated machine.

A cover system includes a cover, two bail arms, and a fluid circuit. Each bail arm is mounted on a gliding assembly. Each gliding assembly includes a gliding body slidably supported on a vehicle frame, and a cylinder connected to the gliding body and defining first and second ends. The fluid circuit is configured to supply fluid to the first end of the first cylinder and the second end of the second cylinder. A fluid line connects the second end of the first cylinder to the first end of the second cylinder and is configured to direct the fluid between the cylinders such that a flow of the fluid to the first cylinder causes movement of the cylinders, gliding bodies, and bail arms in a first direction, and a flow to the second cylinder causes movement of the cylinders, gliding bodies, and bail arms in a second opposite direction.

While the concept of saving automobile's intake of fuel or electricity by converting kinetic energy of an automobile into some form of potential energy, usually either electrical potential or compressed gas potential, in order to later convert that energy back into kinetic energy, has been well recognised over the years, and while the number of regenerative braking techniques and devices have been introduced over the years, with the exception of an electrical engine/generator, these techniques have not been well adapted. That was caused in part by either not a very simple implementation of those devices or by a necessity to completely re-engineer automobile powertrain in order to use those techniques. Present invention introduces a method of regenerative braking where no components of an automobile are to be replaced or removed and none of their functionality is modified. The new component described here is implemented as an additional, one piece, complete device, placed onto the existing automobile wheel's hub, and covered by the automobile's wheel. This method of regenerative braking is therefore applicable to all the automobiles, independent of their power source, to newly built automobiles and the automobiles already on the road.

An excavator has a unitary fluids tank formed from moldable cross linked high density polyethylene. The fluids tank has a compartment for hydraulic fluid and a compartment for power unit fuel. The compartments are separated by a coextensive integral wall providing an insulating barrier are formed from a polyethylene foam providing an insulating barrier between the compartments.

The present invention introduces a retrofit method of regenerative braking where no components of an automobile are to be replaced or removed and not of their functionality is modified. The recovering energy system is implemented as an additional, one piece, complete device, placed onto the existing automobile wheel's hub, and covered by the automobile's wheel. The system includes a housing, turbines, accumulators, and valves which act to both store and dispel energy as needed. This method of regenerative braking is therefore applicable to all the automobiles, independent or their power source, to newly built automobiles and those already on the road.
