PURPOSE:To prevent deterioration in oil hydraulic pressure resisting characteristics caused by residual air by connecting oil passage which is made in the separating plate of the oil feeding device and the oil feeding port provided in the supporting member. CONSTITUTION:Oil is pressed into the buffer from outside by the pressurizing cylinder pump (not indicated in the figure) from the oil feeding port 6 with the cocks 13, 14 removed from the fitting plate 5 and the opening end of the elastic body 1 turned upward. While oil pressed into the buffer is charged into the oil chamber A through the pipe 11 which connects the oil feeding port 6 and the oil passage 10, air in the oil chamber is appropriately discharged to the outside through the orifice 8, blowing pipe 12, and the exhaust port 7 as oil is pressed in. When the oil chamber is filled with oil and the oil reservoir B is charged with oil until the blowing pipe 12 is under the oil surface, injection of oil is finished. |
