SWASH PLATE COMPRESSOR
A swash plate compressor 1 includes a swash plate 3 which rotates around a rotary shaft 2, a piston 4 which moves forward and backward in response to the rotation of the swash plate 3 and in which a hemispherical concave sliding surface 4a is formed, and a shoe 5 in which there are formed a flat end...

| Zusammenfassung: | A swash plate compressor 1 includes a swash plate 3 which rotates around a rotary shaft 2, a piston 4 which moves forward and backward in response to the rotation of the swash plate 3 and in which a hemispherical concave sliding surface 4a is formed, and a shoe 5 in which there are formed a flat end surface portion 12 which comes into sliding contact with the swash plate 3 and a spherical surface portion 11 which comes into sliding contact with the sliding surface 4a of the piston 4.
A columnar portion 13 is formed between the spherical surface portion 11 and the end surface portion 12 in the shoe 5, and in a boundary area between the columnar portion 13 and the spherical surface portion 11, there is formed a spherical-surface-portion side flange 14 which protrudes radially outward and constitutes the spherical surface portion.
The lubrication of the shoe is satisfactorily performed and the entry of foreign matter into the sliding parts can be prevented. |
