1. A mount assembly for a vibrating component, comprising:
- a support mount configured for attachment to a machine element, said support mount being configured to oscillate along a preferred axis;
a supporting mount configured to be rigidly connected to the machine element;
a spring element having first and second sides, said spring element being attached along one of its sides to the supporting mount;
an inertial mass attached along the other side of spring element and being linked to the supporting mount in a manner that permits the oscillatory motion of the inertial mass with respect to the supporting mount along the preferred axis of vibration of the support mount; and
an actuator that comprises a magnet and a coil spaced apart from one another for enabling the controlled oscillatory movement of the inertial mass with respect to the supporting mount, wherein the magnetic field provided by the actuator is oriented so as not to exert a preload on the spring element along the preferred axis of vibration;
wherein the inertial mass and the spring are not contacted by a liquid.

Abstract
An active, vibration-countering mount assembly for a vibrating component is disclosed. The mount assembly comprises a supported mount supported on a machine element, a supporting mount supported via a spring element on the supported mount, and an inertial mass, movable back and forth by means of a drive parallel to the direction of the vibrations introduced by the vibrating component. The inertial mass is joined to the supported mount by a spring such that the inertial mass and the spring are not contacted by a liquid.

10. A mount assembly for a vibrating component, comprising:
-
a support mount having a first end and a second end, said support mount being connected at its first end to the vibrating component; a vibration canceling assembly operatively connected to the second end of the support mount, said vibration canceling assembly comprising a support plate rigidly attached to the support mount, a coil rigidly attached to the support plate, a spring attached at one end to the periphery of the support plate, and an inertial mass connected to the other end of the spring, said inertial mass comprising an annular magnet concentric with the coil, and; an actuator for energizing the coil in a selective manner so as to create a vibratory motion of the inertial mass with respect to the coil that runs counter to the vibrations of the vibrating component; wherein the magnetic field provided by the magnet with respect to the coil when the coil is not energized is oriented so as not to exert a preload on the spring. - View Dependent Claims (11, 12, 13, 14, 15, 16)
