STRUCTURE OF SEMI-ACTIVE MOUNT
First Claim
1. A semi-active mount structure comprising:
- a nozzle plate mounted between an insulator and a diaphragm, to divide an interior of a main case into an upper fluid chamber and a lower fluid chamber, the nozzle plate being formed with first and second fluid passages to guide flow of a fluid;
a plunger mounted in a housing coupled to a lower surface of the diaphragm such that the plunger is vertically movable in the housing, the plunger opening or closing the second fluid passage in accordance with application of electric power to a coil for powering the plunger;
a valve spring disposed between the plunger and the housing, to apply elastic force to the plunger, the valve spring dividing a space defined between the diaphragm and the coil into an upper space and a lower space; and
a valve mounted at a vent hole drilled at one side of the housing for air to be introduced into or discharged from the lower space, the valve opening or closing the vent hole.
