A fluid regulating device includes a valve housing formed with a piston receiving chamber that has a piston member slidingly and sealingly disposed therein to divide the piston receiving chamber into a volume-variable gas compartment filled with pressurized gas and a volume-variable fluid compartment. A regulator receiving chamber has a large-diameter rod receiving section, and a small-diameter fluid channel with a rate control section that is aligned with and that extends from the rod receiving section. The fluid channel interconects fluidly the rod receiving section and the fluid compartment. A fluid regulating rod is disposed inside the regulator receiving chamber, and includes a slide portion slidingly and sealingly disposed in the rod receiving section, and a passage-forming portion that has a cross-section smaller than that of the slide portion to define a fluid passage inside the regulator receiving chamber for communicating fluidly the rate control section and a fluid opening that is in fluid communication with the rod receiving section. A fluid-controlling portion extends from the passage-forming portion and is extendible into the rate control section. An actuated portion extends from the slide portion and outwardly of the regulator receiving chamber.
