  • Patent number: 11458808
    Abstract: A shutter system for use in a vehicle. The shutter system comprises a panel mounted on a conduit through which air flows, the panel having a first plurality of apertures for permitting air to flow therethrough; and a grille movably mounted on a surface of the panel, the grille having a second plurality of apertures for permitting air to flow therethrough. In an open position, the grille is aligned with the panel such that the first and second plurality of apertures are aligned to permit air to flow through both the first and second plurality of apertures. In a closed position, the grille is aligned with the panel such that the first and second plurality of apertures are not aligned and air is blocked from flowing through the first and second plurality of apertures. The shutter system comprises a first actuator mechanism coupled to the panel and the grille and comprising a first bias spring and a first shape-memory alloy (SMA) spring.

  • Patent number: 8353697
    Abstract: An actuator is disposed between a back plate and a manifold and is connected to a valve pin. A nozzle flange, locating ring, or pressure disc can transmit a first load between the manifold and a mold plate. A pressure disc can be disposed between the actuator and the back plate. The pressure disc transmits a second load between the back plate and the manifold through the actuator.
