| 20090272549 | Dry Valve For Sprinkler System - A dry valve is provided for a sprinkler system, including a housing including a valve body having an inlet end and a valve cover having an outlet end. A prime chamber housing is disposed within the housing and defines a prime chamber. A prime piston is disposed within the prime chamber and is movable between a closed position seated against a valve seat and an open position received within the prime chamber. A check valve diaphragm assembly is disposed within the housing and disposed against the prime chamber housing in a closed position and spaced from the prime chamber housing in an open position. | 11-05-2009 |
| 20090294138 | Dry Sprinkler Assembly - A dry pipe sprinkler assembly is provided including a sprinkler body having a thermally responsive trigger mounted thereto. A housing, including an inlet end and an outlet end is provided with the outlet end being connected to the sprinkler body. A seal member is disposed at the inlet end of the housing, and a load mechanism extends between the thermally responsive element and the seal member. The load mechanism may include a support portion, a passage tube portion, and an outlet orifice portion slidably received within the housing and movable within the housing upon activation of the thermally responsive trigger to allow the seal member to be dislodged from the inlet end of the housing to allow suppressant fluid to flow therethrough. The dry pipe sprinkler assembly allows the use of different outlet orifice members to provide dry pipe sprinkler assemblies having different K factors while utilizing common components for the remaining dry pipe sprinkler assembly. | 12-03-2009 |
| 20100236795 | Fire Protection Sprinkler - A fire protection sprinkler includes a sprinkler body having a fluid passage extending therethrough. A plug member disposed in the fluid passage. A heat responsive unit releasably secures the plug member in the fluid passage. A pair of frame arms extend from the sprinkler body. A deflector is mounted to the pair of frame arms and includes a peripheral edge including a plurality of slots extending radially inward from the peripheral edge. The plurality of slots include a pair of slots orthogonal to the pair of frame arms and the deflector includes a pair of apertures radially inward of the pair of slots and orthogonal to the pair of frame arms. The pair of apertures include an inner arcuate portion and a radially outwardly extending portion extending from the inner arcuate portion. | 09-23-2010 |
| 20100276164 | Fire Protection Sprinkler - A fire protection sprinkler is provided with a sprinkler body having a fluid passage defining an inlet end and an outlet end. A plug member is disposed in the fluid passage and a heat responsive unit releasable secures the plug member and the passage. A deflector is mounted to frame arms extending from the sprinkler body and the deflector includes a peripheral edge including a plurality of slots extending radially inward from the peripheral edge. At least two of the plurality of slots have a first outer portion having a first diameter and a second intermediate portion adjacent the first outer portion and having a second diameter less than the first diameter. A third inner portion extends radially inward from the second intermediate portion and has a third diameter greater than the second diameter. The deflector design is utilized for providing a desired water distribution pattern. | 11-04-2010 |
| 20110056709 | Trim Manifold Assembly For A Sprinkler System - A trim manifold assembly is utilized to facilitate control of the control valve in a fire protection system. The trim manifold assembly utilizes a manifold block with numerous passageways to provide desired flow communication between various components, such as automatic and manual valves, check valves, inlet and exit ports, and sensor ports, by way of non-limiting example. The trim manifold assembly can be cost-effectively manufactured and may require less assembly steps. The trim manifold assembly can facilitate the assembly of a fire protection system and the attachment of the trim manifold assembly to the control valve for operation thereof. | 03-10-2011 |
| 20110108290 | Trim Manifold Assembly For A Sprinkler System - A trim manifold assembly includes an alarm block and a release block. The alarm block is in communication with a fire suppressant fluid supply and defines a first alarm passage in communication with an alarm sensor. The release block is coupled to the alarm block and includes a drain passage and a first control passage. The first control passage is in communication with the fire suppressant fluid supply and a pressure-actuated system control valve to control communication between the fire suppressant fluid supply and the sprinkler system. | 05-12-2011 |
