<p>A resilient mounting (1) comprises main (2) and auxiliary (3) fluid chambers between which a restricted flow of damping fluid can take place in use of the mounting (1). The auxiliary chamber (3) is detected at least in part by a flexible membrane (9) of convoluted profile in the unloaded condition such that fluid displaced from the main chamber (2) is accommodated without stretching the membrane (9). Preferably the membrane (9) is formed in a first profile corresponding to that which it adopts in the static load condition and is deflected to said convoluted profile in the unloaded condition. Preferably the membrane (9) is also convoluted in the first profile so that fluid displaced due to both the static load and dynamic working loads is accommodated without stretching the membrane (9). The avoidance of tensile stresses in the membrane (9) improves the fatigue life thereof.</p> |
