Abstract
PURPOSE: To give braking to a piston in a constant speed without reference to the pressure of operation oil in an oil cylinder provided with a damping device to reduce the speed of the piston at the end of a stroke by containing a relief valve inside the damping device.
CONSTITUTION: When pressurized oil is supplied to a right cylinder chamber (b) and a cushion chamber 4' to move a piston 1 to the left, the operation oil in the cylinder chamber (a) is discharged mainly from a cushion chamber 4 through a passage 8 and a feed hole 7. When a small piston 3 for cushion is pushed into a chamber 4, chambers 4 and 6 are disconnected, and the operation oil in the chamber (a) is sent to the feed hole 7 via a side passage 9 provided with a throttle valve 10 for braking a piston 1. At this stage, when the pressure of the operation oil in the chamber (a) is over a set value, a piston 14 in a relief valve 13 is pushed down against a spring 15, and the operation oil is sent out to the feed hole 7 via an oil escape passage 16 opened thereby for giving a constant braking to the piston 1.
