Working principle of YATACO double-acting cylinder

The working principle of YATACO double-acting cylinder

Buffer cylinder For a cylinder with a high speed near the end of the stroke, if necessary measures are not taken, the piston will hit the end cover with a large force (energy), causing

Vibration and damage to parts. In order to make the piston move smoothly at the end of the stroke without causing impact. Buffer devices are added at both ends of the cylinder, generally called buffers

Punch the cylinder. Its working principle is: when the piston moves to the right driven by compressed air, the gas in the right chamber of the cylinder is discharged through the plunger hole 4 and the air hole 8 on the cylinder head

. When the piston moves near the end of the stroke, the buffer plunger 3 on the right side of the piston blocks the plunger hole 4. When the piston continues to move to the right, it is sealed in the right cavity of the cylinder

The remaining gas is compressed and slowly discharged through the throttle valve 6 and the air hole 8. The pressure generated by the compressed gas is the same as that of the piston movement

All the energy is balanced, which means the buffering effect will be achieved, so that the piston will move smoothly at the end of the stroke without impact. Adjust the opening of the throttle valve port 6

is small, the exhaust volume can be controlled, thereby determining the pressure in the compressed volume (called the buffer chamber) to adjust the buffering effect. If the piston is reversed

direction, compressed air is input from the air hole 8, which can directly open the one-way valve 5 and push the piston to move to the left. If the opening of throttle valve 6 is fixed, it cannot be used

Adjustment is called a non-adjustable buffer cylinder.
There are many types of buffer devices installed in the cylinder, and the above is just one of them. Of course, measures can also be taken on the pneumatic circuit to achieve the purpose of buffering
