PURPOSE: A high efficient piston pump is provided to increase durability and efficiency and to reduce noise because air and liquid are transferred by reciprocating a piston inside a cylinder. CONSTITUTION: A high efficient piston pump comprises a cylinder(B), a piston(A), and a frictional agent(H-1). The piston is installed inside the cylinder and reciprocates to left and right sides according to change of magnetic field generating in a coil(G). The piston transfers air or liquid. The frictional agent reduces the noise of a piston pump and increases durability and efficiency. The frictional agent is composed of a resin of which frictional force is low, a teflon material, or an acetal resin. |
