SHOCK ABSORBER Russian patent published in 2003 - IPC

FIELD: mechanical engineering; vibration protection. SUBSTANCE: proposed shock absorber contains elastic cylindrical; housing hermetically filled with damping liquid, and non-linear elastic member which has two stable equilibrium positions. Elastic member is installed inside elastic housing in damping liquid and is made in form of hermetic evacuated capsule. Said evacuated capsule consists of two interconnect instant-return diaphragms. Permanent magnets are secured in central part of each diaphragm on inner surfaces. Permanent magnets are made in form of axially magnetized disks pointed to each other by like poles. EFFECT: simplified design of shock absorber, improved reliability. 2 dwg
