Abstract
1369885 Valves ROCKWELL INTERNATIONAL CORP 10 April 1972 [9 April 1971] 16352/72 Heading F2V The tapered valve plug 14, having a through bore 15, is biased on to its seating 12 by way of two stacks of Bellville spring plates 58, 61 which are centred upon a thrust button 56 and which are contained within cup-shaped sheet-metal retainer 62. The retainer 62 engages one side of one or more flexible stainless steel diaphragm plates 43 which are clamped against the valve body 13 by way of a cap 44 and which, on their other side, are engaged by an adjustable abutment 64. The thrust button 56 and valve plug 14 have interposed therebetween a ball member 55. The biasing assembly is substantially contained within a multi-diameter recess 51-54 formed in the valve plug 14. Rotation of the plug between its open end closed states is effected by way of a spindle 22 a portion 21 of which is engaged in diametral groove 19 formed in a coupling block 18, the block 18 having a second groove 17 which is transverse to groove 19 and which accommodates a diametral rib 16 formed at the small end of the valve plug 14. The valve seat is formed with annular and short recesses 32, 35 and 33, 36, respectively and the valve plug is formed with annular and longitudinal grooves 31, 34 and 38 respectively. The arrangement of these recesses and grooves is such that they are in mutual communication in both the open and closed states of the valve, but in no intermediate state and so receive lubricant from a valve chamber 28. Chamber 28 is supplied with the lubricant from a stick thereof contained within operating spindle 22, forced inwardly by a pressure screw 26, and controlled by a check valve 29.
