(under the class definition) Apparatus which includes an injection nozzle and a valve therefor, an inlet supply passage for spray fluid, a means to store this fluid under pressure for injection after the valve is opened and means responsive to the presence of inlet fluid pressure to bias
the valve closed.
(1) Note. Fluid is usually supplied to a storage reservoir from the supply through a restriction or check valve and discharge occurs when the inlet line is vented to remove its biasing effect.
(2) Note. Other means, e.g., springs or pressure operated means, are normally provided to open the valve when the inlet fluid conduit is vented. During the time that the nozzle inlet is under pressure, fluid is usually bled to an accumulator and this stored fluid is available for discharge when the valve opens.
