FIELD: machine building.
SUBSTANCE: invention describes design of the valve rod and plunger for use with fluid regulators. Example of the fluid regulator includes fluid regulation element (258), having casing (266) containing longitudinal channel (280) between the first end (282) and second end (284), and valve rod (226) located in channel of the fluid regulating element. The connecting coupling (286) connects the valve rod and fluid regulating element with possibility of sliding. The connecting coupling moves from the fluid regulating element for functional disconnection of the fluid regulating element from the loading force applied by the said loaded element (206) of the fluid regulating element, when the fluid regulating element abuts to the valve seat (254) of the fluid regulating element.
EFFECT: improved design.
