Abstract
A variable frequency vibration isolator for isolating vibrations between a base and a load having relative displacement of each other characterized by a pair of coil springs in series with a connector between them. The connector is journally mounted for axial movement in response to spring vibrations. Locking means including a timing circuit for clamping and unclamping the connector against movement, so as to improve vibration isolation at frequencies higher than approximately 2f.sub.n while substantially improving the performance at lower frequencies.
