Product Specifications
Koganei original orifice※Achieves smooth shock absorption by the method.
- ※ A small-diameter hole through which liquid flows.
The gap between the main body wall and the piston serves as an orifice, so the load is not concentrated in one place and a long service life is achieved.
The impact value at the time of impact is kept low, reducing device vibration and noise.

Difference in impact due to orifice structure

Single orifice
Even if the piston rod strokes, the impact value is concentrated in the first half of the stroke because the orifice is fixed at one location.

Multi orifice
By gradually squeezing the orifice, it is soft at first and gradually gives a strong resistance, but since the impact value changes each time it passes through the orifice hole, there is a wave in the impact absorption.

Linear orifice
Since the orifice is narrowed down steplessly, smooth shock absorption is possible.
