Abstract:
1. A hydraulically damping elastomer bearing comprising: a housing; a connection element; an elastomer body connecting said housing and said connection element with one another in a vibration-damping manner; two chambers filled with a fluid; a flow channel connecting said two chambers to one another; a recess in said housing, said recess being associated with said flow channel; a valve arranged in said recess for opening and closing said flow channel, said valve comprising an elastic diaphragm with an embedded insert, wherein said insert comprises a pin plate comprising a plate with a pin; an actuator attached to an outside of said housing for actuating said valve between a closed state and an open state, wherein at least a portion of said elastic diaphragm is arranged in said flow channel when said valve is in a closed state such that said portion of said elastic diaphragm blocks a flow of fluid in said flow channel, said portion of said elastic diaphragm being perpendicular to said flow of fluid when said valve is in said closed state; and a contact plate having a pin receiving recess on one side thereof, said pin receiving recess receiving said pin, said contact plate having a flat surface on another side thereof, wherein said actuator is an electromagnet and said insert is a metallic insert, said electromagnet comprising a magnet, said magnet engaging said flat surface of said contact plate.
