Abstract: A gas regulator (14) is provided for regulating the pressure of a gas flowing from a source (12) of the gas under pressure to a device (24) for using the gas. The regulator (14) includes a housing (26) and a pressure reducing valve (36) in the housing for controlling the flow of gas from an inlet (28) under pressure to an outlet (32) at a regulated pressure. The pressure reducing valve is controlled by a pressure responsive member (40, 44) which is displaced by operating feed and bleed valves (50) coupled to a control chamber (46) of the pressure responsive member. The feed and bleed valves are operated by a high speed solenoid actuator (68). The bleed valve is vented to the outlet of the housing from the control chamber which is maintained at a higher pressure. The high speed solenoid actuator (68) is operated by a controller (18) for controllably varying the output pressure as desired.

Abstract: An electronically modulating gas valve comprising a modulating solenoid for simultaneously displacing two servo regulator diaphragms, one for controlling LP Gas outlet pressure and another for controlling Natural Gas outlet pressure. A switch is used to select operation with either Natural or LP Gas, wherein the switch activates a gas selection solenoid for controlling gas flow through the Natural Gas servo regulator and the LP Gas servo regulator. The servo regulators are factory adjusted for a maximum Natural Gas pressure setting and a maximum LP Gas pressure setting. Thus, the gas valve is convertible from Natural Gas to LP Gas without re-adjustment.

Abstract: Disclosed is a gas inlet device comprising a gas reservoir (5), which is connected via a supply line (11) via a supply flow restrictor (10) which can be closed by a supply valve 13). The gas can be supplied into the antechamber (5) via a control valve (6) and a control flow restrictor (4). As the control valve (6) and the supply valve (13) close the antechamber from the outside, there are only minimal fluctuations in pressure during switching. By this means the pressure in the antechamber (5) can be controlled precisely and the gas flow from the antechamber (5) into the supply line (11) can be set with great precision.

Abstract: A method is for the continuous control of a position of a control valve. A control deviation from a position of the control valve, is determined as a controlled variable, in relation to a reference variable being determined. A manipulated variable is determined from the control deviation, by which manipulated variable the control valve is positioned and/or maintained in the position predefined by the reference variable. The improved method for the control of the position of a control valve, has the effect that failure of a valve position transmitter does not result in failure of the position control loop.

Abstract: A pneumatic actuation control system includes a pressure controller, an eductor and a valve. The pressure controller is capable of directing an amount of fluid to the contained volume such that a pressure within the contained volume exceeds a pressure external to the contained volume by a predefined positive pressure. The pressure controller can also adjust the pressure within the contained volume when the pressure external to the contained volume changes. The eductor can draw fluid from the contained volume to thereby decrease the pressure within the contained volume. The valve is controllably operable in either a pressure mode or a vacuum mode, where the valve either permits the pressure controller to provide fluid to the contained volume, or permits the eductor to draw fluid from the contained volume. As such, the system provides precision pressure control over a broad range of external pressures while compensating for rapid pressure changes.

Abstract: A control valve system having a housing defining an inlet, an outlet, and an exhaust. A first passage extends between the inlet and the outlet and a second passage extends between the outlet and the exhaust. The control valve system includes a first valve disposed within the first passage. The first valve is movable between a closed position and an opened position. Similarly, the control valve system includes a second valve disposed within the second passage. The second valve is movable between a closed position and an opened position. Furthermore, the control valve system includes a regulator circuit operably coupled to the housing, which outputs a pilot pressure in response to an inlet pressure. An actuating member is slidably disposed within the housing and moveable in response to a pressure differential between the outlet and the pilot pressure. The actuating member independently actuates the first valve and the second valve to provide a quick pressure and exhaust feature.

Abstract: The pressure of hydraulic fluid which is supplied to the continuously variable transmission in the power train of a motor vehicle is regulated by an apparatus wherein an adjustable pilot valve can receive fluid from a pilot conduit leading to a pressure reducing valve. The pilot conduit normally receives fluid from a further conduit, wherein the pressure of fluid is at least substantially constant, by way of a flow restrictor. A branch conduit serves to evacuate fluid from the pilot conduit into the pilot valve when the latter is at least partially open. The fluid-discharging end of the flow restrictor confronts the inlet of the branch conduit, and such inlet is narrowed to reduce the likelihood of turbulence developing in the fluid stream flowing from the pilot conduit, across the further conduit and into the inlet of the pilot valve.

Abstract: A method of controlling pressure in a chamber, wherein the pressure in a chamber in which measurement such as laser measurement is conducted is maintained at a set pressure with respect to fluctuations in external atmospheric pressure, characterized by comprising: detecting the external atmospheric pressure, obtaining a long-term flat pressure value with respect to short time fluctuations of the detected external atmospheric pressure, creating a set pressure in the chamber by adding a predetermined pressure to the obtained pressure value, and detecting the pressure in the chamber while introducing external air so that the pressure in the chamber reaches the set pressure.

Abstract: In a two-way solenoid vale, a small diameter portion of a nozzle portion is fitted in a small diameter portion receiving part communicating with an output pressure oil passage and a large diameter portion is fitted in a large diameter portion receiving part communicating with a supply pressure oil passage. An opening of a through-hole formed in the nozzle portion faces the output pressure oil passage by way of the small diameter portion receiving part, and an inner end of the through-hole is opened and closed by a plunger and communicates with a drain port. An orifice port communicating with the through-hole is opened to the large diameter portion receiving part and communicates with the supply pressure oil passage. Since the orifice port is disposed in the solenoid valve, a separate plate for an orifice is not required, oil passage is simplified and the solenoid valve can be installed in an optional position. The output pressure characteristics can be adjusted by merely replacing with a solenoid valve having an orifice port of a different diameter.

Abstract: A fluid pressure regulator has a program controller, a PID controller, a second PID controller, a drive controller, a solenoid-operated valve for supplying a fluid, a solenoid-operated valve for discharging a fluid, a diaphragm, a main valve, and a pressure sensor. Based on a desired preset value and/or a desired control program inputted from an external source, the fluid pressure regulator regulates the pressure or flow rate of the fluid discharged from a discharge port of the main valve. A detecting mechanism is combined with a controlled object for supplying a controlled variable in the controlled object to the second PID controller through a feedback loop.
