Abstract
Abstract A fluid connector apparatus or hydrant including an insulated casing enclosing a valve control element to supply water to a utilization station. A heating element is positioned within the fluid connector apparatus to prevent freezing of liquid therein. A fluid removal line is provided to remove accumulated water from within casing as required. The valve control element, the heating element and, in some applications, the fluid removal line are inserted in the casing in a manner facilitating ease of withdrawal of the elements for maintenance, servicing and replacement of the internal parts of the connector unit as required.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
200 words
A fluid connector for coupling an underground source of fluid to an above-ground surface utilization point comprising: conduit means including a housing having an inlet, an outlet and a flow passage therebetween; said inlet adapted to be attached to an underground source of fluid and said outlet providing an egress adjacent the ground surfaces and adapted to be coupled in fluid communication to a utilization station; fluid control means including a fluid means including a fluid control element disposed within said conduit means to provide control of the fluid flow through the flow passage of said conduit means; said fluid control means including an elongated member for supporting the fluid control element adjacent the inlet and extending through at least a portion of the flow passage to a position adjacent the top of the housing; heating means positioned adjacent the elongated member within the flow passage, said heating means and said fluid control means being disposed in co-axial alignment to facilitate withdrawal thereof from said conduit means; and said heating means including An elongated heating element extending along said elongated member terminating above said fluid control element whereby heat is supplied to the flow passage above said fluid control element.
Claim 2
Dependent Claim
200 words
A fluid connector for coupling an underground source of fluid to an above-ground surface utilization point comprising: conduit means including a housing having an inlet, an outlet and a flow passage therebetween; said inlet adapted to be attached to an underground source of fluid and said outlet providing an egress adjacent the ground surfaces and adapted to be coupled in fluid communication to a utilization station; fluid control means including a fluid means including a fluid control element disposed within said conduit means to provide control of the fluid flow through the flow passage of said conduit means; said fluid control means including an elongated member for supporting the fluid control element adjacent the inlet and extending through at least a portion of the flow passage to a position adjacent the top of the housing; heating means positioned adjacent the elongated member within the flow passage, said heating means and said fluid control means being disposed in co-axial alignment to facilitate withdrawal thereof from said conduit means; and said heating means including An elongated heating element extending along said elongated member terminating above said fluid control element whereby heat is supplied to the flow passage above said fluid control element.
Claim 3
Dependent Claim
33 words
