AIR-OPERATED DRIVE WITH JET ACTUATOR FOR PIPELINE BALL VALVES (VERSIONS) Russian patent published in 2010 - IPC F15B9/03 

Abstract RU 2384758 C1

FIELD: engines and pumps.

SUBSTANCE: proposed driver comprises sequentially coupled control device, motor, reduction gear and screw-link mechanism. The latter includes link, actuator screw, sliding nut, device to absorb kinetic energy of the drive moving parts, the drive representing a pack of plate springs coupled with actuator screw via thrust bearings. Note here that said pack of springs is arranged to limit axial displacement (compression) with no angular shift.

EFFECT: higher reliability.

3 cl, 4 dwg
