Abstract
A pressure regulating transducer for providing a regulated output pressure in response to an electric input signal in which a proportional solenoid operates a valve, and the output pressure from the valve operates against the force generated by the solenoid to establish the position of a valve element for a regulated fluid output pressure. The position of the valve element will vary in response to flow changes, absolute pressure changes, and changes in the inlet or outlet pressures caused by leaks or restrictions, to maintain the designated outlet pressure for the input signal provided. Thus, a predetermined outlet pressure is maintained for each current input value, regardless of flow and/or absolute pressure changes.
