摘要： A single ring sector seal (10) has multiple arcuate sectors (12a, 12b, 12c) arranged circumferentially around a rotating shaft and in floating engagement with a seal housing. Each sector (12) engages each adjacent sector (12) with a slot seal (40) and overlapping joint (38) therebetween to deter leakage. A protruding ridge (36) on each sector (12) engages a low pressure end cover (18) to form a secondary seal. Spring balance seals (28) provide a further seal between the high pressure chambers (20b, 20c) and the chamber (20a) which can be vented while the shaft is rotating and pressurized when the shaft is stationary. Each sector (12) is radially, axially and moment balanced.

摘要： A blocking pin type synchronizer having a high torque to volume ratio. The synchronizer includes two synchronizer cones (42) held apart by blocking pins (40). Disposed between the cones (42) are spring assemblies (62) of novel construction, each spring assembly including a rectangular spring housing (64), a base plate (66), and a pair of opposed leaf springs (68). The housing has opposed slotted side walls (82). The base plate and the springs are each provided with tabs (92), (98) received within the slots for maintaining the base plate and springs in a centered position. The springs hold the spring housing and base plate apart. The cones are provided with recesses (88), surfaces (86) of the base plate being biased into contact with radial outer surfaces of the recesses (88) to maintain the spring assemblies from rotation.
