Abstract
The invention provides a filling device for an inflatable unit, e.g., a pneumatic tire for a car. The device is connectable to a source of air pressure and to a valve for the inflatable unit. The valve has a whistle arranged to produce an audible signal based on a flow of air in the release outlet, and to enable improved handling and sound performance, the whistle comprises a flow-path forming a first leg extending radially from the passage, and a second leg extending about the passage.
Claims20
A filling device for an inflatable unit, the device comprising a body having an inlet connectable to a source of pressure, and an outlet connectable to a valve for the inflatable unit, a passage extending axially between the inlet and the outlet;
- an air-release path from the passage to a release outlet for releasing air in the passage into an external space;
- a valve arranged between the passage and the air-release path and being configured to open at a predefined pressure;
- and a whistle arranged to produce an audible signal based on a flow of air in the air-release path;
- wherein the whistle is configured not to provide the audible signal when the flow of air in the air-release path exceeds an upper flow limit.
A method of filling an inflatable unit by use of a filling device capable of releasing air to an external space at a predetermined air pressure and to produce an audible signal as a consequence of the release of air, the method comprising repeating the steps of:
- filling air into the inflatable unit via the filling device;
- and
- stopping the filling while listening for the audible signal;
- until the audible signal begins when the filling is stopped.
