摘要：
A valve mechanism for delivering time-spaced pulses of coolant air to coog passages within a turbine engine. The mechanism is designed for varying the pulse frequency to ascertain the affect that pulse frequency variations have on the cooling effect. The valve mechanism is manufacturable at relatively low cost, using standard shelf components and easily machined parts.
