ABSTRACT:
Pressurized fluid enters by way of the flow control valve 90 which regulates flow and thus simulated raindrop size, through the fluid supply tube 80 and enters the fixed fluid distributor body 20, past a rotational seal 154 and into the rotating shaft 10, cushioned by the accumulator chamber 50. As the rotating shaft is made to rotate by means of the drive motor 60 and transmission means 70, the radial outlet port(s) 14 sequentially line up momentarily with each side port 26, allowing fluid flow through each outlet tube 30-35 in turn overflowing each respective conical vessel 40-45 to create a fluid drop at the lower point 48 which falls as simulated rain 160 in a desired three dimensional array. Each raindrop is thus timed perfectly according to the speed of rotation of the rotating shaft 10. The transducer 100 produces an electrical pulse for each rotation, also perfectly timed to the raindrops, which is input to the triggered oscillator 110 to ultimately control the strobe light 140. By means of the timing adjuster 120 the triggered oscillator can be sent to run at a faster frequency than the rotating shaft and thus the raindrops, so that each flash of the strobe light reveals individual raindrops 160 slightly earlier in their creation and falling cycle to create the illusion that the drops are falling upward.
