  • Publication number: 20130233406
    Abstract: Systems and methods for a three chamber compensation network for pressure regulators are disclosed. For example, one described pressure regulator includes: an inlet port; a primary chamber coupled to the inlet port by a main valve; an outlet chamber coupled to the primary chamber by one or more venturi; and a control chamber coupled to one or more of the venturi by one or more sensing holes, the control chamber comprising a movable piston configured to vary the position of the main valve.

  • Publication number: 20110284788
    Abstract: A pressure regulator is disclosed. The pressure regulator includes a housing having a supply port and an outlet port interconnected by an opening defined in a sealing seat. The pressure regulator also includes a supply valve assembly having a core and an elastic shell disposed thereon, wherein the elastic shell is configured to seal the opening and a diaphragm assembly biased by a range spring and configured to push on the supply valve, the diaphragm assembly having a working surface area.

  • Publication number: 20100313960
    Abstract: An electro-pneumatic transducer for controlling gas pressure is disclosed. The transducer includes a nozzle body and a valve housing interconnected therebetween by a nozzle and a solenoid assembly including a magnetized valve assembly and a solenoid having a top portion and a bottom portion, which when energized generate a magnetic field having a predetermined polarity in response to which the magnetized valve assembly is actuated to control gas flow through the nozzle. The transducer also includes a control circuit adapted to receive an input signal. The control circuit is configured to energize the solenoid in response to the input signal to generate the magnetic field thereabout to actuate the valve assembly. The transducer further includes a capacitor coupled to the control circuit, wherein upon loss of the input signal, the control circuit signals the capacitor to provide an electrical signal to the solenoid to actuate the valve assembly.

  • Patent number: 7766030
    Abstract: A high pressure transducer is disclosed. The transducer includes a supply inlet configured to provide a gas supply to the high pressure transducer at a supply pressure and a pressure divider section coupled to the supply inlet. The pressure divider section is configured to reduce the supply pressure to a reduced pressure as a function of a first predetermined ratio. The transducer also includes a low pressure control section coupled to the pressure divider section and configured to receiving the gas supply at the reduced pressure and an amplifying section coupled to the low pressure control section. The low pressure control section varies the reduced pressure to produce a variable control pressure to actuate the amplifying section in response thereto. The amplifying section is also configured to multiply the variable control pressure as a function of a second ratio to obtain an output pressure.

  • Patent number: 5469877
    Abstract: An electric to pneumatic transducer including a transducer housing with a primary converting housing section and a relay housing section. The primary converting housing section contains feedback and control electronics and an electronic feedback sensor that are electrically connected. The feedback and control electronics are adapted to be connected to an electronic signal input. The primary converting housing section also contains a nozzle and associated flapper control for controlling the output from the nozzle and the primary converting housing section also contains a bleed orifice. The relay housing section contains a relay control chamber with a positive bias spring that exerts a force on an upper control diaphragm and an associated lower control diaphragm that are in turn associated with a combined exhaust and supply valve.
