ABSTRACT:
This disclosure relates to a flow control device in which the discharge from the nozzle is kept at essentially the same volume rate of flow in spite of fluctuations in the hydraulic pressure upstream from the device by providing a spray body that has a group of radially disposed channels which are perpendicular to the general direction of flow. A flexible spray control washer spaced upstream from these channels responds to hydraulic pressure by pressing into the channels and restricting the flow area of each of these channels in proportion to the applied hydraulic pressure. In this way, the flow area within the chamber is inversely related to the hydraulic pressure in order to maintain a continuous volume rate of flow through the device.
