摘要： A fuel control system for a ram jet engine has a metering orifice 20 controlled by a portion 18 of a stem 17 in accordance with an engine air pressure signal PR, for regulating flow to the main burners of the engine. A further metering orifice 21 downstream of the orifice 20 is controlled by a portion 19 of the stem 17 and regulates flow to the engine pilot burners. Main burner flow is additionally controlled by a valve 30 responsive to engine temperature. The arrangement is such that pilot burner flow is maintained substantially stoichiometric even when main burner flow shuts down in response to a temperature increase.

摘要： A device for coupling a rotary member to an axially movable input stem of a linear displacement transducer comprises an axially movable element which is coupled to the stem and threadedly engages the rotary member. The axially movable element is restrained against rotation by spring loaded detents and has abutments which can engage a lug on the member when the element reaches its limiting axial positions. This engagement causes the element to be rotated with the member and input to the transducer is arrested.
