摘要:
An exemplary sprinkler system includes a liquid supply conduit and a gas supply conduit. A mixing device is coupled to the liquid supply conduit and the gas supply conduit. The mixing device is configured to establish a mixture of liquid from the liquid supply conduit and gas from the gas supply conduit. The mixture has a selected gas-to-liquid ratio. A sprinkler supply conduit is coupled with the mixing device for carrying the mixture downstream from the mixing device. A sprinkler coupled with the sprinkler supply conduit is configured to receive the mixture and to discharge a fire suppression mist.

An exemplary sprinkler system for use within a building includes a plurality of conduits within the building. A plurality of fixtures within the building are coupled with the conduits for providing water from the conduits to at least one individual for personal use. A plurality of sprinkler heads within the building are coupled to the conduits for selectively introducing water from the conduits into at least one portion of the building for fire suppression. A gas source is associated with the sprinkler heads for supplying gas to the sprinkler heads to achieve a fire suppression discharge from the sprinkler heads.

An electrically assisted or actuated continuously variable transmission (CVT) with a first pulley having a first pulley portion for fixed connection to an engine shaft and an axially movable second pulley portion for placement about the engine shaft. A mechanism for assisting a mechanically-actuated CVT includes a nut connected to the movable portion and an electric motor having a screw that is engaged with the nut. The nut is moved axially by rotation of the screw with respect to the nut, assisting mechanical actuators in changing axial spacing between the pulley portions. A variable actuator for actuating a CVT includes a pair of disks coaxially enagaged with the pulley portions, and a roller for contacting the disks at varying inclinations. An electric motor tilts the roller along the axis of rotation, causing the disks to rotate at differing rates to effect a change in axial spacing between the pulley portions.
