Abstract
A hydraulic mount includes a closable bypass and a decoupling membrane. When the bypass is opened, however, the main effect that can be achieved by opening the bypass, namely the decrease in the spring rate at higher frequencies, is worsened. It is thus desirable to render the decoupling membrane ineffective when the bypass is open. The aim is achieved in that the closure device of the bypass includes blocking elements for blocking the decoupling membrane in the first switching position of the closure device when the bypass is open and can be released in the second position of the closure device when the bypass is closed.
