Embodiment Construction

[0012] The following will refer to figure 1 and 2 Embodiments of the present invention are described. For example, a shoe for a swash plate type compressor used in an automotive air conditioner will be introduced. The front and rear sides correspond to the figure 1 left and right in .

[0013] Such as figure 1 Said, reference numeral 10 denotes a cylinder block, and a plurality of cylinder bores 12 are defined in the cylinder block 10 on the identical outer circumference with respect to the central axis of the cylinder block 10 . The cylinder bore 12 extends along the central axis direction of the cylinder block 10 . Each cylinder bore 12 houses a single-headed piston 14 for reciprocating motion. The front end surface of the cylinder block 10 is connected to the front housing 16 , and the rear end surface of the cylinder block 10 is connected to the rear housing 18 through the valve plate assembly 20 . The front casing 16, the rear casing 18 and the cylinder block 10 co...

Abstract

A shoe for use in a swash plate type compressor, interposed between a swash plate and a piston, has a base member and metal plating layer. The base member is made of aluminum alloy. The metal plating layer coats at least a part of surface of the base member. The thickness of the metal plating layer ranges from 20 mu m to 150 mu m.

Description

technical field [0001] The present invention relates to a shoe inserted between a swash plate and a piston of a swash plate type compressor, and more particularly to a shoe made of aluminum alloy; the present invention also relates to a swash plate type compressor having the same. Background technique [0002] A swash plate type compressor compresses gas by converting the rotation of a swash plate into reciprocating motion of a piston. A pair of shoes as sliders are inserted between the high-speed rotating swash plate and the high-speed reciprocating pistons to ensure smooth operation of the swash plate and pistons. For example, a swash plate type compressor used in an automobile air conditioner is particularly required to be light in weight, and therefore, it may be considered to manufacture a shoe as a part of the compressor from an aluminum alloy in order to reduce the weight of the compressor. [0003] The shoes slide against the swash plate and pistons, which are also ...
