Movement controlling strut.

摘要

A strut for limiting movement and vibration of a motor vehicle engine comprises flexible walls (24B) respectively supporting pins (not shown) which are connected to the engine and the body member respectively. As engine movement of vibration takes place, the walls (24B) flex changing the relative volumes of fluid-containing chambers (28 and 30;32 and 34). Helical fluid pressure communication channels (58,60) interconnect the chambers at opposite ends of the strut and control and limit the flexing of the flexible walls (24B) and thus control and limit the movement and vibration of the engine. A further such channel (not shown) can be added which incorporates a movable piston for transmitting the fluid pressure, the piston being lockable to interrupt pressure transmission.
