Nontemperature Sensor Patents (Class 236/99A)
  • Patent number: 5984257
    Abstract: A fluid flow regulating valve using a thermal expansion material. The valve includes a body provided with inlet and outlet ports; a displacement control part in the body, the displacement control part containing the thermal expansion material and displaced toward the outlet port when the thermal expansion material expands, thereby regulating a degree of opening of the outlet port; and a heater for heating the thermal expansion material within the displacement control part. The displacement control part includes a container containing the thermal expansion material, the container being coupled to the body and an expansion plate for regulating the degree of opening of the outlet port by being expanded in accordance with an expansion of the thermal expansion material, the expansion plate being hermetically coupled to the container.

  • Patent number: 4017025
    Abstract: An inlet plenum extends into a control box and opens into the interior of the control box. Conditioned air is introduced into the box through the inlet plenum and flows from the box, to an area being serviced, through an outlet spaced from the plenum opening in the box. A damper is positioned at the plenum opening and it and the plenum at the opening having conforming shapes, i.e., segments of a circle. The damper closes over the discharge opening and, to vary the volume of air flowing through the box, pivots away from the opening about an axis offset from the center of the arc of the damper and the plenum opening. When the damper is closed on the plenum opening, the centers of the arcuate plenum opening and the damper are coincident and, relative to a central plane parallel to air flow through the plenum, are offset from that plane so that the damper is moved away from the plenum opening by air flow.
