Invented in 1933 by Orton Englehart, it quickly found widespread use.
The Rain Bird horizontal action impact-drive sprinkler head was recognized as a historic landmark of agricultural engineering in 1990 by the American Society of Agricultural and Biological Engineers. [3] This invention led to sprinkler irrigation development that currently exceeds 50,000,000 acres (78,000 sq mi; 200,000 km 2) worldwide.

Spray nozzles can have one or more outlets; a multiple outlet nozzle is known as a compound nozzle. Multiple outlets on nozzles are present on spray balls, which have been used in the brewing industry for many years for cleaning casks and kegs. [2] Spray nozzles range from those for heavy duty industrial uses to light duty spray cans or spray ...
In the late 1960s, spray bottles with trigger-style actuators appeared and quickly became popular, as this design was less fatiguing to use. The original pump-style bottle remained more popular for applications like non- aerosol deodorants , where size was a factor and repeated pumps were not required.
In an overhead valve engine the valve lifters are sandwiched between pushrods and the camshaft. A hydraulic tappet, also known as a hydraulic valve lifter or hydraulic lash adjuster, is a device for maintaining zero valve clearance in an internal combustion engine.
