oil brakes for different conditions

Enidine's DA Series oil brakes are perfect for high-energy, heavy-duty applications that require motion control for tension, compression or both.these non-adjustable units with custom throttle bores are designed for specific input conditions and offer single or multiple throttle bore configurations.

When pressure is applied to the oil brake cylinder, the check ball (compression) is forced into its seat. As soon as the piston head moves, oil is forced through the orifice(s) located in the shock tube, creating the required damping force. After the oil has passed through the throttle bore, some of the oil passes through the extension check valve and fills the rod-side end of the shock tube. The remainder of the oil displaced by the piston rod compresses the balancing sponge.


Oil Brakes for Varying Conditions
Enidine's DA Series oil brakes are perfect for high-energy, heavy-duty applications that require motion control for tension, compression or both.these non-adjustable units with custom throttle bores are designed for specific input conditions and offer single or multiple throttle bore configurations.

When pressure is applied to the oil brake cylinder, the check ball (compression) is forced into its seat.

After the oil has passed through the throttle bore, some of the oil passes through the extension check valve and fills the rod-side end of the shock tube. The remainder of the oil displaced by the piston rod compresses the balance sponge.




After the oil brake cylinder is extended, the check ball (extended) is forced into its seat. As soon as the piston head moves, oil is forced through the throttle bore located in the shock absorber tube and the required damping force is generated. The check ball (compression) is opened by the flow of oil filling the blind side of the shock tube.

Enidine's DA Series models can be user-specified with throttle bores to create increasing drag force along the stroke path using multiple throttle bores in the shock tube. This can be beneficial in controlling the speed of a lid as it closes, as the torque changes due to the weight of the lid as it closes.
