Hydraulic damping device

A hydraulic damping device comprising:

• a housing adapted to be secured to a base body;
• first surfaces defining at least one first main liquid chamber within said housing, a first member defining at least one of said first surfaces, said first member expanding and contracting upon input of vibrations in a vertical direction;
• second surfaces defining at least one second main liquid chamber within said housing, a second member defining at least one of said second surfaces, said second member expanding and contracting upon input of vibrations in a horizontal direction;
• third surfaces defining an auxiliary liquid chamber within said housing, a third member defining at least one of said third surfaces, said third member complementarily deforming with expansion and contraction of said first member and said second member, said auxiliary liquid chamber being filled with a damping liquid, said damping liquid being forced to flow one of into and out of said first main liquid chamber and said second main liquid chamber upon vibration input;
• means defining a first passageway for connecting said first main liquid chamber and said axillary liquid chamber;
• means defining a second passageway for connecting said second main liquid chamber and said auxiliary liquid chamber;
• and
• valve means coupled to said first and second passageways for changing openings of said passageways in response to the vibration input, said first passageway and said second passageway being joined, said valve means being disposed at an intersection of said first passageway and said second passage way.
