FIELD: machine building. ^ SUBSTANCE: valve includes valve for control of air flow in holder of moulding. The valve consists of a case with a valve chamber designed for arranging a movable valve element in it. The valve chamber includes an inlet orifice of the device and a pressure inlet orifice. The inlet orifice of the device is located at a distance from the pressure inlet orifice in the direction of valve element travel. When air pressure in the pressure inlet orifice is lower, than in the inlet orifice of the device, then the valve element can travel into an open position located at least partially behind the inlet orifice of the device and the pressure inlet orifice. When air pressure in the pressure inlet orifice is higher, than in the inlet orifice of the device, then the valve element can travel into a close position between the inlet orifice of the device and the pressure inlet orifice thus isolating the inlet orifice of the device from the pressure inlet orifice. Also here are disclosed the holder of the moulding and post-moulding holding device. ^ EFFECT: raised operational reliability. ^ 30 cl, 12 dwg |
