Abstract

SAPATA PARA COMPRESSORES A presente invenção refere-se a uma sapata para compressores, na qual a redução de peso e resistência prática pode ser compatibilizadas uma com a outra, é fornecida. Uma sapata 21 para compressores, de acordo com a invenção, compreende uma parte de base 211 possuindo uma superfície de contato deslizante de placa "swash" 211 a em contato deslizante com uma placa "swash" 8 e uma parte semi-esférica 212 criada de forma integral com a parte de base 211 e possuindo uma superfície de contato deslizante e assento de suporte 212a em contato deslizante com um assento de suporte lOa, que está na forma de uma superfície esférica e fornecido de forma cóncava em um pistão 10. Uma cavidade 213 é formada entre a parte de base 211 e a parte semi-esférica 212. A parte de base 211 e a parte semi-esférica 212 são conectadas uma à outra por uma parte de conexão sólida 214, que passa através dos centros de ambas as partes e se estende em uma direção central de ambas as partes.COMPRESSOR SHOE The present invention relates to a compressor shoe, in which weight reduction and practical resistance can be matched to each other, is provided. A compressor shoe 21 according to the invention comprises a base part 211 having a swash plate sliding contact surface 211a in sliding contact with a swash plate 8 and a semi-spherical portion 212 formed of a integral with base portion 211 and having a sliding contact surface and support seat 212a in sliding contact with a support seat 10a, which is in the form of a spherical surface and concave supplied in a piston 10. A cavity 213 is formed between the base part 211 and the semi-spherical part 212. The base part 211 and the semi-spherical part 212 are connected to each other by a solid connecting part 214, which passes through the centers of both. parts and extends in a central direction from both parts.
