  • Patent number: 4852864
    Abstract: A hydraulic-damping two-chamber engine mount includes a working chamber facing toward an engine, a compensating chamber, and an intermediate plate separating the chambers from each other and having an overflow conduit extending helically therein through which the chambers communicate hydraulically with one another. The intermediate plate has two sides and an outer periphery merging into a cylindrical ring extending beyond both of the sides. The ring has an outer surface with two axially superposed conduits formed therein having ends and extending over at least a portion of the outer periphery of the intermediate plate. The intermediate plate has a longitudinal axis and has a conduit portion formed therein extending obliquely relative to the longitudinal axis through which one end of each of the superposed conduits communicate with each other. An outer conduit wall in the form of a cylindrical mount housing has an inner wall surface covering the superposed conduits.
