(57) A vane type compressor includes a hollow cylindrical housing member and a rotor rotatably
mounted about a longitudinal axis within it. The rotor is formed with a generally
radially extending slot for slidably receiving a vane. This vane is formed generally
in a rectangular parallelopipedal slab shape, and has two opposite substantially mutually
parallel side surfaces which, when the vane is thus fitted to the rotor, extend in
planes substantially radial and substantially longitudinal to the rotor and slide
against the surfaces of its slot. The vane also has a side edge portion, substantially
perpendicular to its side surfaces and joining them, which, when the vane is thus
fitted to the rotor, extends in a plane substantially circumferential and substantially
longitudinal of the rotor and slides against the inner surface of the hollow cylindrical
compressor housing member. The vane is manufactured from a matrix of metal reinforced
with short fiber material, with the orientation of the fibers of the reinforcing short
fiber material being generally two dimensionally random and isotropic in planes perpendicular
both to its opposite side surfaces and to its edge portion and substantially perpendicular
to the longitud- al direction of the compression rotor. Thereby both the bending strength
and also the anti wear characteristic of the vane are markedly improved, and the anti
scuffing and anti seizure characteristics thereof are also enhanced.
