Utilized disc flow control assembly for a restrictor valve
This patent describes a flow restrictor multiple orifice valve having its body counterbored opposite one valve port defining an annular outwardly facing shoulder for receiving superposed multiple orifice discs adjacent the shoulder in face to face axial alignment with the one port. The body has a lateral port communicating with the counterbore. It comprises: cage means including a sleeve loosely disposed in the counterbore and normally sealing with the annular shoulder and surrounding the discs, the sleeve having a wall port in axial alignment with the lateral port and having an elongated wall slot normal to and opposite the wall port; inwardly projecting guide means on the body slidably received by the sleeve slot for preventing angular rotation of the sleeve relative to the valve body.
