Abstract: An electrically-powered fluid sprayer employs a piezoelectric fluid pump that includes an inlet port, an outlet port, a pump chamber, and a piezoelectric element that is deformed and displaced by electrical signals supplied thereto to vary the volume of the pump chamber. Such displacement pumps fluid into the inlet port and into the pump chamber and discharges fluid from the pump chamber out the outlet port. The inlet port is in fluid-communication with a fluid reservoir. Spin mechanics may be disposed downstream from the outlet port of the fluid pump and upstream from the discharge nozzle. The piezoelectric fluid sprayer may be extended to include a dual chamber piezoelectric pump that pumps different fluids (e.g., a liquid and air). The output of the dual chamber pump is mixed in a manifold and supplied downstream to the discharge nozzle. Spin mechanics may be employed in the fluid stream upstream from the discharge nozzle after the mixing.

Abstract: An improved liquid impingement nozzle having two openings along an axis, spaced apart and angled towards each other. A non-atomized liquid stream of the same liquid is directed through each opening by a pressurized source. The two streams meet at an apex distal from the front of the nozzle to create a flat triangular pattern of liquid. The inner shape of the nozzle is substantially conical reducing turbulence and dead zones within the nozzle, thereby reducing build-up and clogging.

Abstract: An impact sprinkler drive is provided by an impact arm or spoon that rotates out of and counter-rotates into a water stream to impact and forward re-align a water emission portion from which the water stream emits. The impact arm is designed to, upon sufficient rotation, interfere with the water stream to reduce back-impact and reverse re-alignment of the water stream. The impact arm may be an impact spoon formed on an impact disc. The impact spoon is configured to increase the energy for forward re-alignment of the water emission portion including an increased length to permit a time delay before water flowing through the spoon applies force away from the water stream. The water acts upon spoon portions positioned at increased radial distances so that the water acts with a greater torque arm to impart rotational energy.

Abstract: An automotive vehicle includes a vehicle body and at least one reservoir containing a fire suppressant agent. A distribution system receives the fire suppression agent from the reservoir and conducts the agent to at least one location about the vehicle's body in response to the determination by a sensor system and controller that the vehicle has been subjected to a significant impact. The sensor system and controller determine not only the magnitude of an impact upon the vehicle, but also track subsequent motion of the vehicle, as well as the time which has elapsed since an impact, so as to decide if and when the fire suppressant agent should be dispersed. Alternatively, the fire suppressant agent may be dispersed following activation of a manual switch.
