Definitions
- FIG. 2 is a sectional view of a guillotine discharge system of the LP compressor of a turbojet engine
- the system of discharge valves is guillotine, that is to say that the discharge air outlet is effected through a circular duct 16 formed by two radial flanges and extending from the vein primary 4.
- This duct may be obstructed or discovered by a ring 14, said guillotine ring, which can move axially and come to cover the duct 16 (as in the case of the closure shown in the upper figure), or discover it (case of the bottom figure) to let out the air from the primary vein 4 when it is desired to discharge the output of the compressor BP 2.
- the displacement of the ring 14 is provided by an angled arm 17 whose one end is attached to the ring 14 while its second end is attached, directly or indirectly, to the rod of the control cylinder 15.
- Figure 5 shows the installation in the second chamber of the control device of the discharge valves, according to the invention.
- the outer wall of the interveines housing, which closes the speakers January 1 to 13, has been removed to reveal the interior thereof.
- the second chamber 12 is constituted by a circumferential succession of elementary enclosures which are separated from each other by the arms 6 of the intermediate casing 7.
- the control device is here represented by a jack 15 and an arm 1 both positioned in one of the elementary speaker seconds; it is obvious that several devices of this type are generally regularly distributed over the circumference of the intermediate casing 7.
- the ring 14 extends on the circumference of the intervein crankcase 10 at its first enclosure January 1 and is shown in a position where it partially discovers the conduit 16 discharging the discharged air.
