Abstract

"DISPOSIçãO CONSTRUTIVA EM PISTãO HIDRáULICO PARA CADEIRA DE CABELEIREIRO". Compreendido por um pistão central (1) cujo envoltório externo, ou seja a camisa (2), foi concebida por processo de injeção de nylon, tendo incluída nesse envoltório uma bucha (3) que serve de alojamento para uma válvula de, esfera (4) que está alinhada com um cilindro (5) no qual funciona um pistão cilíndrico (6) dotado de um pino responsável pela abertura da válvula de esfera quando solicitado, dito pistão cilíndrico (6) estando submetido à ação de uma mola de retomo (8) e achando-se apoiado num pino (9) com canal longitudinal (10) e pelo qual é injetado o óleo que é bombeado através de pedal anexo à peça, sendo todo o conjunto protegido por um invólucro em duas partes ligeiramente cónicas (1 1) e (12) unidas entre si por meio de parafusos periféricos (13)."CONSTRUCTIVE ARRANGEMENT IN HYDRAULIC PISTON FOR HAIRDRESSER CHAIR". Comprised of a central piston (1) whose outer casing, that is, the liner (2), was designed by a nylon injection process, having included in this wrap a bushing (3) that serves as a housing for a ball valve (4 ) which is aligned with a cylinder (5) in which a cylindrical piston (6) is fitted with a pin responsible for opening the ball valve when requested, said cylindrical piston (6) being subjected to the action of a return spring (8 ) and being supported on a pin (9) with a longitudinal channel (10) and through which the oil is injected, which is pumped through a pedal attached to the part, the whole set being protected by a housing in two slightly conical parts (1 1 ) and (12) joined together by means of peripheral screws (13).
