Abstract

"COMPRESSOR ALTERNATIVO". é descrito um compressor alternativo que compreende um pistão com um caminho de sucção conectado a um espaço de compressão nele; uma válvula de sucção montada numa superfície extrema do pistão para abrir e fechar o caminho de sucção; um conjunto de válvula de descarga montado num lado de descarga do cilindro para controlar a descarga de gás pela abertura e fechamento do espaço de compressão; e uma unidade de prevenção de aderência formada na superfície da porção extrema do pistão ou na porção de contato do pistão e da válvula de sucção para minimizar a aderência de óleo pela redução da área de contato entre o pistão e a válvula de sucção."ALTERNATE COMPRESSOR". An alternative compressor is described which comprises a piston with a suction path connected to a compression space therein; a suction valve mounted on an extreme piston surface to open and close the suction path; a discharge valve assembly mounted on a discharge side of the cylinder to control gas discharge by opening and closing the compression space; and an adhesion prevention unit formed on the surface of the piston end portion or the contact portion of the piston and suction valve to minimize oil adhesion by reducing the contact area between the piston and the suction valve.
