    Abstract: A partition arrangement for separating a rear combustion chamber space having a propulsion nozzle leading from the rear end thereof from a forward chamber. The partition includes a partition wall disposed between the forward end of the rear chamber and the rear end of the forward chamber which has a pair of symmetrically arranged flow passages. Sealing plugs are detachably insertable into these passages so as to accommodate sealing of the chambers from one another during operation of the rear chamber as a combustion chamber supplying the nozzle and for permitting flow of pressurized gases from the forward chamber through the hollow passages and the rear chamber when the plugs are removed from the passages. The plugs are mounted so as to be movable from the inserted to the released positions while remaining inside of the rear chamber at positions spaced from the nozzle so as to prevent the plugs tampering nozzle operation. Preferred embodiments of the arrangement for holding the sealing plugs include a centrally disposed trunion on the partition wall which supports the sealing plugs for a predetermined axial movement against a stop collar on the trunion and a subsequent rotational movement of a holding member with attached sealing plugs for moving the plugs out of axial alignment with the passages. A helically coiled spring mounted on the trunnion and the holding member provides the lateral forces for pivoting the plugs laterally. A stop pin is arranged on the partition wall for preventing application of the rotational torque by the spring until after the plugs have moved rearwardly axially out of engagement with the passages. Another preferred embodiment utilizes a slot and pin arrangement at the centrally disposed trunion for guiding movement of the plugs in the axial and lateral directions in a predetermined path in response to the pressure forces in the forward chamber.
