Abstract
A method of leak testing a component 5 containing a functional fluid is disclosed. The method comprises positioning the component 5 in a vessel 4 that defines a chamber 6, reducing the pressure of the fluid in the chamber 6, supplying a carrier fluid to the chamber 6 and simultaneously pumping fluid from the chamber 6 using a fluid detection device 26, and using the fluid detection device 26 to monitor for the presence of the functional fluid.
Claims23
A method of leak testing a component containing a functional fluid, the method comprising:
- positioning the component within a vessel, the vessel defining a chamber;
- reducing the pressure of a fluid in the chamber;
- supplying a carrier fluid to the chamber and simultaneously pumping fluid from the chamber through a fluid detection device;
- and
- using the fluid detection device to monitor for the presence of the functional fluid.
A leak testing apparatus for leak testing a fluid containing component at a reduced pressure, the apparatus comprising:
- a vessel that defines a chamber, the vessel having a carrier fluid inlet;
- a fluid detection device in fluid communication with the chamber;
- and
- a pumping system that is configured to reduce the pressure of the fluid in the chamber and to pump fluid from the chamber through the fluid detection device.

A method of leak testing a component containing a functional fluid, the method comprising:
- positioning the component within a chamber of a vessel;
- then
- reducing the pressure of the fluid in the chamber using a vacuum pump;
- and simultaneously
- pumping fluid from the chamber through a fluid detection device using a pump of the fluid detection device and monitoring the fluid for the presence of the functional fluid and/or for an abnormal background fluid.
