The rod of the gate passes through the guiding bushing for permitting sliding with respect to it, is spring-loaded with respect to the guiding bushing in the direction to the seat, and is provided with the member that is made of a thermosensitive material and causes the gate to be opened. The member is made of a rod. The rod passes through the opening made in the gate rod. The rod is mounted in the housing, and its ends abut against the ring step made in the wall of the space. The thermosensitive material has shape memory and is preliminary bent and allows the gate to move in the direction to the seat under the action of the spring.
EFFECT: simplified design and reduced cost of servicing.
