ABSTRACT:
A motor mount having hydraulic damping comprises a support member and a support bearing or wall which are connected by an elastic support spring of circular ring shape and together define an operating space. The operating space is separated from a compensating space by a partition wall connected to the support bearing or wall. The operating space and the compensating space are connected by a connecting aperture or conduit. The conduit penetrates the partition wall and is interrupted by at least one cavity of variable volume. The part sections of the conduit formed thereby have a cross-section reduced stepwise in the direction from the operating space to the compensating space. This gives the motor bearing a wide-band damping effect.
