Document Type and Number:
Japanese Patent JPS61265366
Kind Code:

Abstract:

PURPOSE: To improve a degree of abrasion resistance in a cylinder block, by constituting this cylinder block with an aluminum alloy containing a specified quantity of silicon, while fitting a plastic ring in a ring groove of a piston.

CONSTITUTION: A cylinder block 25 consists of an aluminum alloy containing silicon at a range of 16 to 20wt%. In a part of a piston coming into slidingly contact with a cylinder 27, there is provided with a ring groove 34, and in this ring groove 34, the piston 31 slides inside the cylinder 27 via a sliding ring 35 consisting of such plastics as being excellent in abrasion resistance and slidability, for example, polytetrafluoroethylene resin. Therefore, the abrasion resistance of the cylinder block 25 is well improved, while the piston 31 smoothly slides inside the cylinder 27 as keeping airtightness.
