1. A vaporizing pressure regulator comprising:
- a valve body having a flow path extending therethrough and a pressure responsive valve carried in said flow path to regulate the flow of a fluid through said flow path; and
a heat source operatively associated with the valve body in close proximity with the flow path whereby the valve body heats fluid in the flow path.

Abstract
A vaporizing pressure regulator is provided, comprising: a valve body having a flow path therethrough and a pressure responsive valve carried in the flow path to regulate the flow of a fluid; and a heat source operatively associated with the valve body to heat fluid in the flow path by thermal conduction through a portion of the valve housing. In another aspect of the invention, heating is enhanced by providing power to the heat source proportional to the difference between a measured temperature indicative of the temperature of the fluid and a predetermined temperature.

8. A vaporizing pressure regulator comprising:
-
a valve body having a flow path extending therethrough;
a valve carried in the flow path to regulate the flow of a fluid flowing through the flow path;
a heat source operatively associated with the valve body for heating fluid in the flow path;
a temperature measuring sensor providing an electrical signal 8 indicative of the temperature of the fluid in the flow path; and
a control circuit responsive to the electrical signal for controlling the heat source and maintaining a predetermined fluid temperature in the flow path. - View Dependent Claims (9, 10)

11. A vaporizing pressure regulator comprising:
-
a valve body having a flow path extending therethrough;
a pressure responsive valve in the flow path for regulating the flow of fluid through the flow path;
an electrically powered heater carried in said valve body proximate to said flow path for heating the valve body and a fluid flowing through the flow path;
a temperature measuring sensor operatively associated with the valve body for providing a signal indicative of the fluid temperature in the flow path; and
a control circuit providing power to said heater proportional to the difference between a measured temperature signal from the sensor and a signal representative of a predetermined fluid temperature. - View Dependent Claims (12)
