Abstract
A hydraulic mount apparatus comprises a housing having an upper portion and a lower portion and defining a housing chamber. A partition member disposed therein and divides the housing chamber into a pumping chamber and a receiving chamber. A decoupler including a magnetic actuator is attached to the partition member. A moving member is disposed in the pumping chamber and attached to the decoupler. The moving member includes at least two magnetic inserts disposed therein, spaced from one another, to move the moving member from a first position to a second position in response to a magnetic field. The first position is defined as the moving member being spaced from the decoupler. The second position is defined as the moving member being attached to the decoupler.

A hydraulic mount apparatus comprising:
- a housing having an upper portion and a lower portion disposed on a center axis and defining a housing chamber;
- a partition member disposed in said housing chamber dividing said housing chamber into a pumping chamber and a receiving chamber with said pumping chamber being between said upper portion and said partition member and said receiving chamber being between said lower portion and said partition member;
- a decoupler including a magnetic actuator attached to said partition member separating said pumping chamber and said receiving chamber;
- a moving member of elastomeric material disposed in said pumping chamber attached to said decoupler;
- and
- said moving member including at least two magnetic inserts disposed in said moving member, radially spaced apart from one another to move said moving member from a first position to a second position in response to a magnetic field, said first position being defined as said moving member being spaced from said decoupler, said second position being defined as said moving member being attached to said decoupler,
- wherein said elastomeric material of said moving member entirely surrounds said at least two magnetic inserts to enclose said at least two magnetic inserts in said moving member.

- a squeeze plate disposed in said pumping chamber and adjacent to said moving member to secure said moving member between said squeeze plate and said decoupler;
- and
- said squeeze plate including a solid portion spaced from the moving member defining a gap and a protrusion extending outwardly from said solid portion to said moving member to secure said moving member between said squeeze plate and said decoupler;
- wherein said elastomeric material of said moving member entirely surrounds said at least two magnetic inserts to enclose said at least two magnetic inserts in said moving member.
