Abstract:
A valve testing device and method for determining whether a fluid control valve, such as an automatic transmission valve, is operating acceptably. The device and method of the present invention passes pressurized fluid through the valve and to a flow measuring means where the flow rate of fluid through the valve can be measured. Because contamination within such a valve can contribute to unacceptable flow rate measurements, the device and method of the present invention can also pass purge fluid through the valve in a direction that is opposite to the normal flow of working fluid through the valve.
