  • PNEUMATIC FIRE DETECTOR
    Publication number: 20110121977
    Abstract: A pneumatic fire detector is disclosed having a switch module comprising a manifold operatively connected to a sensor tube, the switch module incorporating respective forming tubes for applying a sufficient pressure to the outer surface of an installed diaphragm to deform it and thereafter the diaphragm is exposed to a pre-determined pressure through the manifold to deform the diaphragm outwards and into contact with a respective switch.

  • SNUBBER VALVE
    Publication number: 20090173402
    Abstract: A snubber valve provides velocity- and/or position-dependent mechanical snubbing. The snubber comprises pressure sensing pins controlling the position of a float that changes the cross section of a fluid flow channel in the valve. In some embodiments, the pins sense their position in the valve, controlling the position of a float that changes the cross section of a fluid flow channel in the valve. Also provided are methods for snubbing, for example, an aircraft door.
