cylindrical housing 8 to allow access to and visual inspection of the mounts one of the co located mount pairs is shown in more detail in fig5 a first sandwich anti vibration mount 14 a includes a rigid end support member that includes a reaction plate 18 a a mounting plate 20 a and a support bracket 22 a similarly a second sandwich anti vibration mount 14 b includes a rigid end support member that includes a reaction plate 18 b a mounting plate 20 b and a support bracket 22 b the mounting plates 20 a 20 b include openings to enable the end support members to be mechanically secured to circumferentially spaced parts of the annular structural member 6 by bolts 24 in the arrangement shown in fig3 to 5 each end support member is mechanically secured using three bolts however it will be readily appreciated that the number of bolts will depend on the size and fixing requirements of the mounts a rigid intermediate support member 26 is located between the first and second mounts 14 a 14 b and is mechanically secured to one end of an axially extending structural member 28 of the stator assembly 1 as shown in fig4 and 5 since the arrangement shown in fig3 has four mounting locations 12 a 12 d then there are four structural members 28 but only two are shown in fig4 each structural member.
