Dry Shock Absorber

The dry shock absorber 10 may be employed to control inertia load shocks in mechanical devices.

As shown in Fig. 1, compressed air is routed through a pressure regulator 11. The regulator is adjusted to a pressure as required to achieve desired deceleration of load.

The optional adjustable pressure relief valve 12 prevents pressure changes in the cylinder 13, when the piston 14 compresses the air column during the working cycle. The relief valve 12 is needed where large cylinders or long piston strokes are required.

In operation, the regulated air pressure enters the "in port" 15 on the cylinder
13. Air pressure pushes the piston back, retracting the piston rod 16 and the rod clevis 17. A load attached to the rod clevis 17 has to overcome the force of air pressure against the piston 14 during the working cycle. In this manner control of shocks in the load is provided.

Fig. 2 shows a dry shock absorber 10 as coupled to a typical reciprocating load. In pos. 1, the piston rod 16 is retracted. As the index drive 18 moves a swing bar 19 to pos. 2, the piston 14 is pulled forward against the regulated air pressure, thereby providing a controlled shock absorbing load.
