  • Patent number: 9346147
    Abstract: An orifice assembly for a liquid jet cutting system includes a generally cylindrical base, an orifice member, and an orifice cap. The base includes a conduit that extends through a central axis from a top surface to a bottom surface of the base. The base also includes a pedestal that defines a protrusion from the top surface, the pedestal having a planar top region substantially parallel to the planar bottom region of the base. The orifice member sits on the planar top region of the pedestal. The orifice member defines an intermediate conduit therethrough, the intermediate conduit in fluid communication with the base conduit. The orifice cap defines an upper conduit therethrough, the upper conduit in fluid communication with the intermediate conduit of the orifice member. The orifice cap is configured to secure the orifice member to the pedestal.
