    Abstract: It is an object of the present invention to reduce the abrasion at a pressure receiving portion of the cylinder block, without increasing the manufacturing cost, even when the outer rings of a bearing are jointly rotated and eccentrically fluctuated. The cylinder blocks are made of aluminum alloy comprising, by weight, 1.5 to 3.5% of Cu, 13 to 16% of Si, 0.5% or less of Mg, 1.0% or less of Zn, 1.0% or less of Fe and the remainder of Al. The matrix, except for primary Si crystal, is relatively soft. Primary Si crystals which each independently project from the pressure receiving portions tend to be pushed into the base material by the outer rings of the thrust bearings, so that the levels of primary Si crystals are easily made to be approximately uniform. As a result, the interference and thrust load from the outer rings can be appropriately supported by a large number of primary Si crystals, and a jointly rotating motion and an eccentric fluctuation can be appropriately supported by a large number of primary Si crystals under severe operating conditions.

    Abstract: A rotary vane compressor comprises a cylinder having two closed ends defining a cylinder chamber in which is rotatably mounted a rotor. The rotor carries a plurality of radially movable vanes which move radially into sliding contact with the inner surface of the cylinder chamber during rotation of the rotor to compress a refrigerant gas. The rotor is rotationally driven by a rotor shaft rotatably mounted by bearings in the cylinder ends. To prevent destruction of the ozone layer, a refrigerant containing no chlorine, such as HFC-134a (1,1,1,2-tetrafluoroethane; CH.sub.2 FCF.sub.3) is used, and to compensate for the inferior lubricating properties of the chlorine-free refrigerant, the bearings are provided with a manganese phosphate coating of 10 .mu.m-15 .mu.m thickness to prevent cohesion and seizure of the mutually contacting surfaces of the bearings and rotor shaft.

    Abstract: A sacrificial body mitigates cavitation damage to components within a pump. The sacrificial body is mounted in the pump so that flowing fluid passes over the sacrificial body, which causes the sacrificial body to shed electrons into the flowing fluid in the vicinity of the cavitation. The excess electrons tend to suppress hydrogen ions from releasing, which can mitigate cavitation. The sacrificial body is formed of a material having less resistance to corrosion due to the flowing fluid than the components of the pump. Needles are attached to the sacrificial body for immersion in the flowing fluid to facilitate the release of the electrons for the sacrificial body.
