ABSTRACT:
A mount for damping vibratory motion has a resilient pad which is flexed by the motion to move relatively spaced bumper and counter shoulders for resiliently damping vibrations having amplitudes less than the spacing of the shoulders. Low frequency vibrations with larger amplitudes are damped hydraulically by a diaphragm arrangement operated by engagement of the shoulders and throttling an hydraulic fluid between working and expansion spaces enclosed thereby. The diaphragm arrangement is spaced from the resilient pad so that the pad- and hydraulic-damping operate independently. The shoulders are also outside the enclosed space for the hydraulic fluid to be similarly independent thereof.
