Abstract

DISPOSITIVO DE AMORTECIMENTO DE PULSAÇÃO DE FILTRO. Trata-se de um elemento de filtro substituível (200) que inclui um meio de filtro anular (202) que define uma passagem central (219), um tubo central (206) que é disposto dentro da passagem central (219) do meio de filtro anular (202) que define um reservatório central (204), uma extremidade aberta superior (220) unida ao tubo central (206), sendo que a extremidade aberta superior (220) inclui uma abertura (210) que permite que o fluido flua a partir do reservatório central (204) para fora do elemento de filtro (200), uma extremidade aberta inferior (222) unida ao tubo central (206), oposta à extremidade aberta superior (220), e um dispositivo de amortecimento de pulsação de filtro (224) que inclui um defletor de elemento de filtro (236’) que se estende longitudinalmente para cima a partir do elemento de filtro (200).
