Abstract

An automatic and adjustable valving mechanism in which a spray of pressurized fluid from an aerosol can, is released in intermittent sprays occurring in cycles of adjustable length. The valving mechanism consists of a body having an actuating bar mounted on drive rods which can be latched in an elevated position by a latch plate. Contact between the actuating bar and the nozzle of a pressure source, such as an aerosol can, releases pressurized fluid from the aerosol can into a first internal chamber of the valving mechanism. The pressurized fluid acts upon a diaphragm to force hydraulic fluid from the first chamber into a second chamber, which raises a piston which, in turn, raises the rods supporting the actuating bar, to terminate the discharge of the pressurized fluid from the aerosol can. The raising of the drive rods supporting the actuating bar permits a latch plate to lock the drive rods in an elevated position while a sufficient transfer of hydraulic fluid from the first chamber to the second opens a discharge conduit for the valving mechanism. A release of the pressurized fluid from the valving mechanism permits the piston rod to drop and disengage the latch plate from the drive rods so that the actuating bar can again contact the aerosol can nozzle for initiating a further cycle. In one embodiment, the aerosol can contains a pine tree scent and the valving mechanism, as well as the aerosol can are mounted within a lighted ornament which may be attached to an artificial Christmas tree.
