Abstract RU 2184298 C2

FIELD: rocketry and space engineering; spacecraft life-support systems. SUBSTANCE: valve has body, shut-off member with spring and pneumatic drive which consists of two pistons mounted in succession. Spring in body is mounted towards opening of shut-off member. Pistons of pneumatic drive are so mounted that when control pressure is fed to them, they press shut-off member towards its closing. EFFECT: enhanced operational reliability due to opening of valve by relieving control pressure in both branches of control pressure system. 2 dwg
