Abstract: 861,217. Valves. SHUFORD MILLS Inc. July 2, 1957 [Feb. 12, 1957], No. 20835/57. Class 135. [Also in Group XXIV] A pressure-regulating valve for controlling the pressure of air to a belt-tensioning device (see Group XXIV) comprises an interconnected inlet valve member e and exhaust valve member f controlling the inlet through a seat c from a supply passage g to an outlet passage h and the exhaust from passage h through a seat d to atmosphere. The inlet seating c is fixed centrally in a sleeve 76 with parts communicating respectively with the passages g and h while the exhaust seating d is carried on a diaphragm 69 loaded by a spring 74. The pressure in outlet passage h acts on the diaphragm against the force of spring 74. If the pressure is too high the seat d moves away from valve member f to relieve the pressure while if too low the diaphragm moves the valve member e off its seating c to supply more air from passage g. A spring 80 urges the inlet seating member to the left-hand end of sleeve 76 and a spring 80 urges valve members e, f towards closed positions. A screw 75 serves for adjustment of the spring 74 and hence the regulated pressure. Specifications 845,722, 845,724 and 845,725 are referred to.
