Abstract
A fluid regulating device includes a regulator housing that confines a valve receiving chamber and a fluid chamber filled with hydraulic fluid. The regulator housing is formed with a fluid opening that is in fluid communication with the valve receiving chamber and that is connected fluidly to a fluid port of a hydraulic cylinder device. A pneumatic cylinder device includes a cylinder housing with a piston member slidingly and sealingly disposed therein to divide the same into a volume-variable pressurized gas compartment and a volume-variable fluid compartment which is in fluid communication with the fluid chamber via a fluid aperture. A regulating valve unit is disposed in the valve receiving chamber to control flow rate of the hydraulic fluid between the fluid opening and the fluid chamber.
