US Patent 7757703 Device for regulating pressure

A pressure regulator is provided. In one embodiment, the pressure regulator includes a body having an internal cavity for receiving a pressurized medium and inlet and outlet ports that enable a pressurized medium to enter the internal cavity at a first pressure and exit at a second pressure. The exemplary pressure regulator also includes a control piston disposed within the internal cavity that is configured to move in response to a change in pressure within the internal cavity. The pressure regulator of this embodiment also includes a damping feature within the internal cavity that is configured to oppose the movement of the control piston. Other embodiments of pressure regulators and systems are also provided.
