Abstract
PURPOSE:To increase the corrosion- and wear-resistance of a piston by forming the inner wall surface of a cylinder or the sliding surface between a piston and a cap-seal by means of ceramic material and specifying the roughness of the surface of the piston. CONSTITUTION:When a piston 1 made of ceramic material, which is of a circular cylindrical shape, makes a reciprocal movement in the arrow-marked direction, the fluid in a cylinder 2 is sent out. The cylinder 2 is provided with a cap-seal 3 made of soft rubber like neoprene or Viton. This seal 3 exercises a sealing effect when it slides on the surface of the piston 1. In this case, in order to ensure both good sealing performance and high wear-resistance, the surface roughness of the piston 1 is finished to 0.15-0.4mum. Meanwhile, alumina, zirconia, silicon carbide, silicon nitride, etc. are used as the ceramic material.
