Abstract
The present invention is directed to devices for controlling the fluid flow and pressure, including adjustable pressure regulators, pressure regulators with an inlet restrictor, semi-automatic valve and pressure regulator with a by-pass valve. The adjustable pressure regulators have a movable shuttle, shuttle housing, a high pressure diaphragm, a low pressure diaphragm and a fluidic conduit connecting the inlet to the outlet. One or more of these components are adjusted to modify the outlet pressure of the regulator. The inlet restrictor allows incoming fluid to enter the pressure regulators when the pressure of the incoming fluid is higher than a threshold level. The positioning the inlet restrictor can be used to prevent a partial vacuum from forming inside a pressure regulator. The semi-automatic valve is opened manually but closes automatically when fluid flowing through the valve is insufficient to keep the valve open. The semi-automatic valve can also be a semi-automatic electrical switch. The by-pass valve directs the flow to bypass the pressure regulator, when the flow is slow or has low pressure.
