ABSTRACT:
A swash plate (3) incorporated in a swash plate type compressor and comprising a boss (10) typically formed of aluminum material, which is fixedly secured on a drive shaft (2), and a swash plate assembly (11) extending obliquely from the boss (10), which assembly comprises a pair of front and rear contact plates (12) made of iron and brought into contact with a pair of shoes (6) which are accommodated in recesses (15a) of a piston (5), a connecting member (13) made of iron rigidly connecting the pair of contact plates (12), and a filler (14) made of aluminum material which completely fills the internal spaced formed between the contact plates (12). According to this structure, the change of the distance between recesses (15a) for accommodating the shoes (6) due to the expansion or shrinkage of the piston (5) is compensated by the change of the thickness of the plate assembly (11), whereby the shoe clearance is always kept constant even during a high speed operation of the compressor or in an operation in a low temperature atmosphere, while the slidability of the shoe (6) against the contact plate (12) is maintained at the same level.
