FIELD: mechanical engineering; removal of excessive pressure from reservoirs of reduction gears, gear-boxes and other mechanisms. ^ SUBSTANCE: proposed breather has stepped housing 1 with air escape hole, cap 6 and hemispherical dampening element 5. Rod 2 is fitted in air escape hole. Upper part of rod 2 is provided with circular groove. Lower part of rod 2 which is taper in shape extends beyond housing. Dampening element 5 is received by circular groove of rod 2. Cap 6 mounted immovably on housing 1 is provided with slots 7 in its lower part. Clearance is formed in between bottom of cap 6 and end face of rod 2. As soon as pressure reaches its excessive level, rod moves upward letting the air outside through clearance formed between dampening element 5 and through hole of housing 1, flat and slots 7. ^ EFFECT: enhanced operational reliability; avoidance of water penetration inside mechanism at immersion of breather in aqua medium. ^ 4 dwg
