поступает в трубопровод высокого гивлени 3. При падении давлени в канале 2 и трубопроводе высокого давлени 3 игла 6 под действием пружины 4 и давлени в полости 9 прижимаетс к седлу 5.enters the high pipeline 3. When the pressure in the channel 2 and the high pressure pipe 3 drops, the needle 6 is pressed against the saddle 5 by the action of the spring 4 and the pressure in the cavity 9.
Такое выполнение позвол ет уменьшить упругость механической пружины, облегчить услови ее работь, что способствует повышению надежН (х;ти нагнетательного клапана.Such an embodiment reduces the elasticity of the mechanical spring and makes it easier to work, which contributes to an increase in reliability (x; and pressure valve).

A METHOD FOR PRESSING METAL NL CASTING MACHINES UNDER PRESSURE AND EM1 There are known devices for pressing metal on pressure casting machines containing a pressing cylinder, a multiplier and a control system with channels, pipelines and spools 5C in order to improve the reliability of the proposed device, the supply channel can be used by the flow control channel. From the pressure source to the norsion nolot of the cylinder of the pressing of the extension in the corus of the multinlikator and is led to the coping [hole of the multiplier plunger, at the end of which are flattened flats. 15The device consists of a cylinder / piston 2 with a piston 2, a housing of a cartoon animator 20, a Norsh 4 with a plunger 5. At the end of which there are flats 6.
