Abstract
In a swash-plate type rotary compression, a pair of cylinder blocks are formed of an aluminum alloy containing 16 to 20 weight % silicon. A ring made of a synthetic resin having wear resistance and slidability is fitted in a ring groove formed in a sliding surface of each of pistons which is brought into sliding contact with the corresponding cylinder bore, or a coating layer formed of a ferrous metal is provided on the above sliding surface. A drive shaft is fitted in a central bore in each of the cylinder blocks such that radial load exerted by the drive shaft is directly borne by an inner peripheral surface of the central bore, and an oil passageway supplies lubricating oil to a clearance between an outer peripheral surface of the drive shaft and the inner peripheral surface of the central bore.
