  • INSULATED HOSE AND INSULATED HOSE COUPLING COVER
    Publication number: 20170016563
    Abstract: The insulated hose coupling cover includes a first main collar, a first valve seat and a first valve. An insulated hose is also formed. The first passageway of the first main collar is aligned with the first passageway of the first valve seat. An actuator engages the first valve and moves the first valve with respect to the first valve seat between a first position and a second position. In the first position, the first passageway of the first valve is not aligned with the first passageway of the first main collar and the first passageway of the first valve seat. In the second position, the first passageway of the first valve is aligned with the first passageway of the first main collar and the first passageway of the first valve seat permits communication between an annular space and the first passageway of the first main collar.
