Abstract

1340570 Valves; conveying rotary motion RESEARCH ENG CO 29 April 1971 12163/71 Headings F2V and F2Q Upon energization of solenoid 36, lever 37 shifts clutch sleeve 33 rightwards to engage dog 42 and thereby transmit rotation from unidirectional motorized gear-box 40 to a threaded shaft 60 co-operating with a ball-nut 61 which moves leftwards against spring 55 to rotate valve spindle 15 via crank 21. The gear-box is so arranged that upon subsequent de-energization of the motor, the spring 55 is unable to return the nut 61 until the solenoid 36 is de-energized to disengage the clutch and permit free rotation of shaft 60.
