  • Patent number: 4562861
    Abstract: Thermal conduction through a liquid line is deterred when liquid is not flowing through it by lodging a double-acting spring-centered plunger in a constricted section of a passage connecting opposite ends of a barrel in the line. Such plunger can be displaced from the passage constricted section in either direction to a passage expanded section automatically by pressure of liquid in the line resulting from opening a valve in the line.
