Abstract (en)
[origin: US6123008A] A compact transportable compressed-air piston engine for paint-spraying devices, dosing pumps, grease guns or the like, makes it possible, without much effort, to carry out various length working strokes of a working piston. A compact engine is obtained by mounting the control in/on the cylinder head or in/on the cylinder bottom with axes extending transversely with respect to a main axis so that stroke changes can be achieved solely by the working piston contacting the valve piston rods of switch valves. In addition, return springs are not needed in the switch valves, which are required for reversing and are operated by the working piston.
