  • Heat shield and apparatus comprising same
    Patent number: 4202552
    Abstract: A heat shield, for example, for a pump for liquid sodium, formed so that the space between the shield and a wall can be optimally sealed during operation. The heat shield thus retains more radiant heat and prevents a disturbance of a rotation-symmetrical thermal condition. To achieve the object, the heat shield, in one form, consists of two layers of materials having different coefficients of expansion, and in an alternative form, of two parts the spacing between which can be adjusted by mechanical means in a pivoting manner.
