ABSTRACT:
A fluid choke for controlling fluid flow, such as condensate draining from a high pressure steam line, that does not require the use of any separate filters and constructed entirely from a section of bar stock including a reduced diameter inlet section having a small orifice extending axially therethrough with a plurality of radially extending openings from the orifice to its outer diameter to prevent the accumulation of foreign matter in the orifice, and a larger diameter outlet section having a larger diameter and longer orifice extending axially therethrough communicating with the inlet section orifice that serves to provide a pressure drop permitting the inlet section orifice to be somewhat larger in diameter, further reducing the possibility of foreign matter accumulation in the inlet orifice section and also reducing the amount of flashing in the inlet section.
