A spring/damper comprises inner and outer members (12, 14) connected by an elastomeric shear spring (16) and having a main fluid chamber (26) defined therebetween which communicates with a second fluid chamber (36) in the inner member through a restricted orifice (40). There is an elastomeric bladder (42) within the second fluid chamber which is chargeable with gas. There may also be axially-spaced circumferential wear rings (60) on the bladder (42) to minimize bladder abrasion against the inner wall of the inner member (12). An elastomeric ring (64) attached to the inner member (12) within the main fluid chamber engages the outer member when the damper bottoms out and this seals the restricted orifice (40) against flow of fluid therethrough from the main fluid chamber (26) to the second fluid chamber (36). The restricted orifice (40) includes an elastomeric restrictor having a yieldable flap (130) covering a passage (112) for blocking flow therethrough in one direction while providing flow in a reverse direction. <IMAGE> |
