Abstract: A piston pump for a backpack sprayer, which operates reliably without damage due to scoring of the wall of the piston cylinder by powders such as wetable solids, which tend to be abrasive and score or scratch the piston cylinder wall which is of plastic material. The pump has a plastic piston cylinder. A liner provided by a sleeve of metal which is not subject to scratching and is of sufficient thickness to maintain a cylindrical shape of the piston wall. The seal of the piston rides on the piston wall liner as the piston reciprocates in pumping the spraying liquid and particles suspended therein from a tank into a pressure chamber in the tank, from which pressure chamber the spraying liquid is extracted for spraying via a hose and a spraying nozzle. The sleeve is molded upon injection of the plastic providing the piston cylinder pump by being mounted on a core having a step which partially overlaps an edge of the sleeve. Upon injection of the plastic and cooling thereof in the mold, the sleeve is captured and held against axial movement in the cylinder by a step in the plastic which partially overlaps the end of the sleeve. Preferably the sleeve is metal which is harder than the particles of the spraying liquid, and may suitably be of stainless steel.

Abstract: There is provided a cylinder injection type internal combustion engine capable of performing stratified charge operation at the time of a vehicle speed of 120 km/h and/or an engine rotational speed of 3200 rpm to enhance the fuel efficiency and/or to observe the emission regulations. In the internal combustion engine, a stratum of air and/or air flow is formed between a fuel spray injected from an injection valve and the top face of a piston and/or the wall surface of a combustion chamber, and a face shape contrived to guide the air flow is formed on the top face of the piston. Also, the stratified charge operation can be performed even at the time of cold start or cranking.
