ABSTRACT:
A flow control valve having a valve chamber which is adapted to receive fluid under pressure and which comprises a valve member having a surface with a groove therein and an outlet passage terminating at one end in a port in the groove. A resilient element is provided in the valve chamber in confronting relationship with the groove. The resilient element has an aperture in registry with the groove. The resilient element and the valve member are mounted for relative movement so as to change the relative position of the groove and the aperture, and this permits the manual selection of the flow rate. The pressure in the valve chamber urges the resilient element into the groove an amount which is dependent on the magnitude of the pressure. In this way the selected flow rate is made independent of inlet pressure fluctuations.
