Abstract

A hydromount for mounting a motor vehicle unit is disclosed. The hydromount includes a supporting spring supporting a mount core and surrounding a working chamber, and a compensation chamber separated from the working chamber by a dividing wall and delimited by a compensation diaphragm. In embodiments, the compensation chamber and the working chamber are filled with a liquid and are connected by a damping duct incorporated into the dividing wall. In an embodiment, the dividing wall has two dividing plates between which a diaphragm is accommodated in a manner capable of oscillating. In an embodiment, the diaphragm and the dividing wall delimit an air chamber connected to the environment via an opening in the dividing wall, and the opening can be unblocked and closed by a switchable non-return device having a pressure-actuatable non-return valve with an opening pressure set to or having an oscillation amplitude of the diaphragm.
