Abstract: A valve for fire suppression sprinkler systems is disclosed. The valve has a chamber with an inlet and an outlet. A closure member, positioned within the chamber, is movable to close and open the inlet. A latch engages the closure member to hold it in the closed position. The latch also engages a deformable diaphragm. The diaphragm deforms in response to pressure applied to it and allows the latch to move between a latched position engaged with the closure member and an unlatched position away from the closure member. When the diaphragm is depressurized it allows the latch to move and disengage from the closure member, which opens under fluid pressure from the inlet and allows fluid to flow through the valve.

Abstract: Granule distributing apparatus comprises a container (1) having a discharge opening (3) for a product to be distributed and a duct member (6) connected to the discharge opening provides a distribution chamber (64) for the product. The duct member (6) is foldable between working and storage positions. In the working position it projects away from the container (1) and allows products to pass through the discharge opening (3) and along the distribution channel (64). In its storage position the duct member (6) obturates the discharge opening (3) and extends over the top of the container. A locking member (5) is preferably provided which is manipulatable to locate the duct member (6) in the working position and also serves to close an entry end of the distribution channel (64) when the duct member is in the storage position.

Abstract: A pressure regulating valve reduces the increased internal pressure in an aerosol spray can, filled with compressed gas, to a working pressure level for a spray valve (12). A regulating piston (52) is kept in equilibrium by a restoring force, and a sealing point (66, 68) is provided, which is closed at a pressure in the pressure regulation chamber (84) that is above the regulated pressure level. To prevent the precision of regulation from being adulterated by the decreasing internal pressure of the can as its contents are progressively withdrawn, a sealing means (86, 66; 67) is proposed, which seals off one free end of the piston (52, 74) from the internal pressure of the can and the regulated pressure. The variable internal pressure of the can is therefore no longer able to act on any axial face of the piston (52), and despite what may be a smaller piston face area, the precision of regulation is improved.

Abstract: An energy efficient water sprinkler has a housing with primary and secondary water chambers each with a turning wheel for translating the force of impacting water to rotational motion of a central shaft journal. Water is forced through a central channel in the rotating shaft and discharged from the housing. A portion of the discharged water is directed to deflection fins on the outer surface of the housing to further impart rotational or energy to the rotating shaft.

Abstract: A perfume spray head structure generally comprises a main body, a spray nozzle, a gas guide device, and a gas supply tube, wherein the spray nozzle, the gas guide device, and the gas supply tube are pre-assembled together and then coupled with the main body. By the use of the pre-assembled structure, the assembly process can be performed conveniently and the occurrence of displacement can be avoided. In addition, the spray head has gaps formed thereon for passage of gas and perfume liquid. The perfume liquid is sprayed out via the gaps so as to form uniform perfume mists. The perfume spray head structure of the present invention can avoid the occurrence of non-uniform spray mists, which is caused by the displacement of the spray channel.

Abstract: A portable, battery-powered sprayer for dispensing two liquid products at the same time. A reservoir cartridge having two liquid chambers is removably installable in a reciprocating bay in the housing.

Abstract: Toy water guns include a housing supporting a liquid storage chamber, a conduit for establishing fluid communication between the chamber and a discharge orifice disposed proximate a front end of the housing, a trigger mechanism, a fluid transfer system adapted to develop forces for causing a continuous or pulsed stream of liquid to flow through the conduit and out of the discharge orifice when the trigger is pressed. A first embodiment employs a rotatable nozzle assembly that is dimensioned and arranged to spin as it receives a stream of liquid via the conduit. The nozzle assembly ejects a stream of liquid as it spins to thereby obtain a helical “tornado” flow pattern. In a second embodiment, a fixed or movable deflector is used so that water exiting a nozzle strikes a surface of the deflector to thereby develop a “wave” or “hard rain” discharge pattern. Multiple modes of operation are also contemplated.
