ABSTRACT:
A gas turbine engine (10) includes a multi-stage combustion chamber (19) having a pilot stage (22) and a main stage (24), wherein during the low power setting only the pilot stage (22) is operating. During the non-operation of the main stage (24) a problem of coking occurs in a fuel supply system in general, and in a check valve (30) distributing fuel to the main stage, in particular. The check valve (30) is cooled by pilot fuel flowing through an auxiliary chamber (52) and is insulated by an air jacket (60) that is formed between the outer housing and the inner housing of the check valve.
