The present invention relates to an active engine mount device mounted on a vehicle, and more specifically, to a bypass flow path opening/closing type-active engine mount device using an air chamber allowing contraction/expansion to be adjusted by a solenoid valve when a bypass flow path is opened/closed, thereby optimizing a loss factor and dynamic characteristics. According to the present invention, the bypass flow path opening/closing type-active engine mount device using the air chamber has a liquid chamber allowing a liquid to be sealed into the interior of the housing and comprises: a separation plate; a primary flow path; an orifice plate; and an air chamber. The separation plate is mounted on the interior of the liquid chamber and has a space formed on the center thereof to divide the liquid chamber into an upper liquid chamber and a liquid chamber. The primary flow path is formed to be connected to the upper liquid chamber and the lower liquid chamber. The orifice plate is arranged on the lower side of the space formed in the center of the separation plate and has the bypass flow path formed thereon to be connected to the lower liquid chamber. The air chamber is arranged between the space formed in the center of the separation plate and the orifice plate and has a size that changes to open and close the bypass flow path. |
