A hydraulically damped vibration isolating elastomeric mount, such as a motor mount, in which a working chamber is defined by an elastomeric spring element, a support, a mounting base, and an end wall to the chamber which can flex towards and away from the working chamber. The end wall has an elastic mounting means allowing it to contact a stop surface at the limit of its travel. The elastic mounting means is connected directly to the mounting base, and the stop surface is associated rigidly with the base. The end wall is thus freely movable when acoustically undesirable vibrations are induced in the mount and their transmission through the mount is reduced. The end wall can be fixed in position by vacuum or mechanical means so that vibration damping of the mount is effected by allowing the hydraulic fluid to pass in and out of the chamber through a flow restricting orifice. This provides damping of larger amplitude lower frequency vibration such as when a mounted motor is at or near idling speed.
