ORIFICE PLATE FOR AN ENGINE MOUNT IN WHICH MAGNETORHEOLOGICAL FLUID IS INJECTED, CAPABLE OF IMPROVING THE CONTROL EFFICIENCY OF THE MAGNETORHEOLOGICAL FLUID

摘要

PURPOSE: An orifice plate for an engine mount in which MR(MagnetoRheological) fluid is injected is provided to efficiently control flowing property of the MR fluid.;CONSTITUTION: An orifice plate for an engine mount in which MR fluid is injected comprises a coil assembly(40), a core assembly unit, and a fluid path separator. The core assembly unit comprises a coil(41) wound to form a ring shape and a cover(42) connected to the outside of the coil. The core assembly unit comprises a first core(10), a second core(20), and a cover plate(30). The first core includes a large diameter and comprises a first inlet unit(13) opened to a fluid path. The second core includes a small diameter and is connected to an upper part of the first core. The cover plate including a diameter same to the first core is connected to the upper part of the second core and comprises a second inlet unit(31) opened to the fluid path. The fluid path separator is installed between the first inlet unit and the second inlet unit and controls the flow of the MR fluid passing through the fluid path.;COPYRIGHT KIPO 2013;[Reference numerals] (AA,BB) Flow path
