Buffer plunger: Generally installed at the end of the piston rod or cylinder head. When the oil cylinder reaches the end of its stroke, the buffer plunger first enters the buffer chamber.

Buffer chamber: A specially designed space connected to the working chamber. When the buffer plunger enters, it compresses the oil inside, generating a buffering force.

Throttle hole: Set between the buffer chamber and working chamber, or on the buffer plunger. The size and number of throttle holes adjust the magnitude and buffering effect.
