Abstract
The invention provides a flywheel system comprising a flywheel mounted for rotation within a chamber, a vacuum pump system and a valve for selectively closing a passage, wherein the chamber is coupled to an inlet of the vacuum pump system via the passage. The invention also provides a method of controlling the starting and stopping of the flywheel system.
Claims20
A flywheel system comprising:
- a flywheel;
- a chamber within which said flywheel is provided;
- a passage for connecting the chamber to an inlet of a vacuum pump;
- and
- a valve which selectively opens or closes said passage, wherein the flywheel is mechanically coupled to the vacuum pump thereby to impart rotational drive from the flywheel to the vacuum pump.
2 more elements
A flywheel system comprising:
- a flywheel;
- a chamber within which said flywheel is provided;
- a passage for connecting the chamber to an inlet of a vacuum pump;
- a valve arranged to selectively open or close said passage;
- and
- a controller which determines a chamber pressure value corresponding to a pressure in the chamber;
- determines a maximum allowable flywheel speed value based on the determined chamber pressure value;
- and controls the flywheel to limit the speed of the flywheel to be below the determined maximum allowable flywheel speed value.
5 more elements
A flywheel system comprising:
- a flywheel;
- a chamber within which said flywheel is provided;
- a passage for connecting the chamber to an inlet of a vacuum pump;
- and
- a valve which selectively opens or closes said passage, at least partially based upon a chamber pressure value corresponding to a pressure in the chamber, and wherein the valve opens the passage when said chamber pressure value exceeds a value that is between 4 and 8 mbar.
