A pressure stabilization differentiator comprises a unit of executive signals with a body, wherein a piston connected to valve, a support with adjustable screw and spring between the support and piston are arranged, pressurized air source and recipients. Between the pressurized air source and recipient a signal converter is arranged, this is connected to unit in which body arranged are a basic diaphragm connected through a rod to the valve, a cover pressing the diaphragm to the body with formation of rod end and rodless chamber with spring arranged between the diaphragm and support with adjustable screw. The signal converter comprises a body, first and second diaphragms that connected by thrust and form with the body an intermediate chamber. First and second diaphragms are pressed against the body by covers with formation of first and second chambers. The rod end is connected to the pressurized air source directly and to recipients through pneumatic circuit and rod valve. The rodless chamber and intermediate chamber are connected to the recipients through pneumatic circuit, second chamber of converter through pneumatic circuit and additionally mounted flow-control valve, and first chamber is connected through openings in the cover to atmosphere. |
