ABSTRACT:
The damping of transducers having a mass oscillating in the manner of a piston in a cylinder containing damping fluid on both sides of the cylinder is rendered adjustable by the provision of a conduit through the mass for the flow of damping fluid from and to either side of the oscillating mass. An adjustable valve is preferably provided in a part of that conduit for damping control through regulation of damping fluid flow.
