Deschner’s Slow Return model Kinechek speed regulator will control the speed of a load pushing on the plunger rod with the same smooth, constant rate as a regular Kinechek. With the added Slow Return feature, the automatic extension of the plunger rod is slowed by a fixed restricting orifice built-in to the unit's internal flow passages. Slow Return Kinecheks are often built into the slide mechanisms used on 2nd operation production lathes during multi process production.
