A vacuum dry sprinkler system includes a sprinkler head formed with a body having a central orifice through which fire extinguishing fluid is expelled through an outlet end. A yoke, attached to the exterior surface of the sprinkler body, extends beyond the outlet end of the sprinkler body and is connected at its apex to a deflector. A thermally sensitive trigger member is coupled to the yoke and the outlet end of the sprinkler head. The sprinkler body carries an expulsion assembly which includes an expulsion member and a thrust member. In response to a fire, the expulsion member of the expulsion assembly overcomes the vacuum force and expels the sealing assembly out of the outlet end of the sprinkler body, while the thrust member laterally thrusts the sealing member out of the water trajectory path, and thus, prevents the sealing assembly from reseating on the outlet of the sprinkler head.
