Title:
ELECTRONIC PRESSURE REGULATOR
Document Type and Number:
WIPO Patent Application WO/2010/146469
Kind Code:
A3
Abstract:
A pressure regulator includes a valve, mechanical advantage device, actuator, controller and pressure sensor. The valve is disposed between an inlet port and an outlet port. The valve includes a pintle and seat.. An actuator is provided to move the pintle away from the seat to allow the flow of gas from the inlet port to the outlet port and a pintle return spring is provided to bias the pintle towards seat. The actuator is configured to move the pintle in response to the magnitude of a control signal. A control system is provided to receive a gas pressure signal from a pressure transducer at the outlet port which detects the gas pressure at the outlet port and generate a control signal having a magnitude proportional to the detected gas pressure.
