Abstract

PURPOSE: To prevent the production of an abnormal noise and vibration caused by suddenly opening or closing the valve by communication two cylinder chambers, which are partitioned off by the piston linked to the valve, with a pipe having a regulator valve.
CONSTITUTION: The cylinder 20 is divided into two chambers 22, 23 by the piston 21, one end of the piston rod is connected to the piston and the other end is linked to the valve 12. Two chambers are communicated with a pipe 25 that has a regulator valve 26. Oil introduced from the inlet 28 into the cylinder is always contained in both the chambers through the communicating pipe, the ascent and descent of piston are performed by flowing oil in the pipe 25. The opening and closing speeds of the valve linked to the piston is dependent on the quantity of oil flowing in the pipe 25, the oil quantity is determined by the regulator valve 26.
