FIELD: control device.
SUBSTANCE: disclosed is fluid medium flow control device containing throttle cartridge, diaphragm unit and control element. Throttle cartridge forms supply channel and upper flat surface. Cartridge supply channel is located along volume booster supply path, and upper flat surface is located along volume booster discharge path. Diaphragm unit forms discharge channel passing along discharge path. Control element is arranged with possibility to displace in throttle cartridge and comprises supply gate, discharge gate and rod. Supply gate interacts with cartridge supply channel, and discharge gate interacts with discharge channel. Discharge gate additionally contains lower flat surface, which is coplanar with throttle cartridge upper flat surface.
EFFECT: improving control accuracy.
