摘要： 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.

摘要： A laminar flow path (34) is opened into the vortex chambers (33a and 33b) from inner peripheral surfaces that face in radial directions of the vortex chambers (33a and 33b) being aimed in circumferential directions of the vortex chambers (33a and 33b) among wall surfaces defining the vortex chambers (33a and 33b). A communication hole (32b) is opened into the vortex chamber (33a and 33b) from an end surface that faces in a direction of center axis of the vortex chamber (33a and 33b) being aimed in a direction of a center axis among the wall surfaces defining the vortex chamber (33a and 33b). Blocking members (36a and 36b) extending in the direction of the center axis so as to surround the communication hole (32b) from an outside in the radial direction are provided within the vortex chambers (33a and 33b). The blocking members (36a and 36b) are provided with flow openings (37a and 37b) penetrating the blocking members (36a and 36b). The vortex chambers (33a and 33b) form circulating flows of a liquid according to a flow speed of the liquid flowing in from the laminar flow path (34) and allows the liquid to flow out from the communication hole (32b) through the flow openings (37a and 37b). Therefore, simplification of structure and facilitation of manufacture are achieved while maintaining product characteristics of a vibration damping device.
