ABSTRACT:
A throttle device for applying a back pressure to a high viscosity point in an airless paint supply system. The throttle device comprises a tube member having an inner through hole and an elongated core member inserted in the tube member and extending along the length of the tube member. A support means supports the core member relative to the tube member and a clearance is provided between the tube member and the core member to constitute a passage for the paint, the clearance being equal to or larger than 1.5 millimeters, and the length of the tube member being selected in relation to the clearance so as to cause a required loss of pressure.
