<p>A user-friendly pressure regulating device and method of using the device are provided. The pressure regulating device comprises (a) a hollow casing (10), (b) a valve system (30) positioned inside the hollow casing (10), (c) a fluid inlet connected to the valve system (30), (d) a fluid outlet (12), (e) a fluid conduit (40) positioned inside the hollow casing (10) between the fluid inlet (end of casing 10) and the fluid outlet (12), (f) a pressure-sensing structure (e.g., a piston (50)) attached to the conduit (40) and being movable inside the hollow casing (10) and attached to the pressure sensing structure (50). (g) A pressure generating structure disposed inside the hollow casing (10) and attached to the pressure sensing structure (50). The pressure generating structure (60) can exert a bias force upon the pressure sensing structure (50) in proportion to a desired pressure in the inflatable object. The pressure regulator can inflate the object when the initial pressure inside the inflatable object is lower than the desired pressure and automatically terminates inflation when the pressure inside the object reaches the desired pressure.</p> |
