Abstract:
A hydraulic engine mount is provided having at least one channel provided within the engine mount. The channel is provided fully enclosed within the engine mount. The channel includes at least two restrictions operable to partially restrict fluid flow through the channel thereby preventing unwanted noise heard by the user. The at least two restrictions include at least one protrusion extending away from a side wall of the channel. Two protrusions are provided to form each restriction where the protrusions are opposed and spaced apart extending into the channel. The at least one protrusion includes at least one sloped wall. The at least one sloped wall is disposed upstream of the fluid through the channel and may be positioned adjacent to an inlet or an outlet of the channel.
