Abstract

SISTEMA DE PROTEÇÃO DA HASTE DE PISTÃO DE CILINDRO HIDRÁULICO. Um sistema de proteção para um pistão de cilindro hidráulico tendo um barril e uma haste de pistão alternando no mesmo, o sistema de proteção compreendendo uma proteção de haste de pistão que é fixada em relação à haste de pistão em uso para se mover em relação ao cilindro para cobrir a haste de pistão, quando a haste do pistão for exposta a partir do barril, e em que a proteção da haste do pistão compreende um material flexível não metálico que retorna à forma após a deformação.
