TW201250139A - The screw-type capillary module with restriction length being adjustable - Google Patents

Abstract

The calibration screw can be used to adjust the effective length for restriction of the screw-type capillary, capillary screw and curved surface are manufactured on both ends of restriction stud, respectively. Another surface is manufactured on the end of calibration screw, both surfaces are matched for the contact transmission between calibration screw and restriction stud. Move calibration screw to change the effective length of capillary screw which determines the restriction of capillary. The motion can be transmitted from calibration screw to restriction stud due to the contact between both surfaces that make the independence between both screws such that self-alignment of restriction screw can be attained and accuracy of restriction hole that contain restriction stud cannot be influenced by the assembly clearance of calibration screw.
