Abstract

1,201,634. Screw-and-nut actuators. NEW YORK AIR BRAKE CO. 5 Oct., 1967 [10 Oct., 1966], No. 45596/67. Heading B8J. [Also in Divisions F2 and H2] An actuator for operating a valve having a duct 11 with a valve plug 10 comprises a first screw member 15 arranged for non-rotative axial movement and connected to the plug 10 by a valve stem 12 and collar 16 with a set screw 17. The position of member 15 is indicated by an arrow 19 movable along a fixed indicator 20. A second screw member 25 threadedly engages the first screw member 15 and is rotated by a motor 28 through a gear 26 fixed on the second screw member 25. The member 25 has a nut 45 fixed to it by a set screw 46 and this provides an abutment shoulder 47 on which is a thrust bearing 48 engaging a collar 49 on non-threaded portion 38 of the member 25. A collar 37 is also on non- threaded portion 38 and is spaced from lower portion 41 of the gear 26 by a thrust bearing 40, a snap ring 42 ensuring no play between the gear 26 and collar 37. The second screw member 25 is generally axially fixed but is subject to slight axial movement being loaded by resilient means consisting of concave and convex washers 50 between the collars 37, 49 which collars are held against rotation and tend to be spread apart by the washers 50. A spindle 60 extends from the upper end of the member 25 and has a radial disc 61 projecting between normally closed switches 62, 63 with plungers 64, 65. To open the valve, switch 75, Fig. 2, is thrown downwardly so that the motor 28 rotates so as to move member 15 upwardly. At the limit of this movement there is a reaction causing compression of the washers 50 by the member 25 being tended to move downwards and thus the motor 28 is switched off by operation of the switch 63. Conversely, when the valve is to be closed, the switch 75 is thrown upwardly and, when the plug 10 engages valve seat 23 there is a movement of the member 25 upwardly so as to open the switch 62 and switch off the motor 28. The motor 28 will also be stopped if any obstruction interferes with the movement of the valve in any intermediate position. In case the actuator is used otherwise than for control of a valve, abutment 72 on member 15 co-operates with stops 70, 71 to define the end positions.
