PULSE GENERATOR Russian patent published in 1995 - IPC

FIELD: pneumatic computing systems. SUBSTANCE: pulse generator has pneumatic relay whose output is connected via inertia link to first blind chamber and to inlet of reservoir, upper level setters made in form of remotely controlled digital-analog converter and low level setter made in form of one-diaphragm setter; setters are connected to each other and to second blind chamber of pneumatic relay directly and through choke - to supply channel. Reservoir is divided into chambers by means of spring-loaded sensitive element: one chamber is connected with atmosphere and other chamber is connected with inlet of reservoir. Digital-analog converter is made in form of one-diaphragm setters at different stiffness of springs connected by circuit of selecting the maximum signal and connected in series according to number of setters of shut-off devices; inlet of each shut-off device is connected with nozzle of respective setter where inlet of one shut-off device is connected with connecting point of upper and lower lever setters; inlet of last shut-off device is connected with atmosphere and nozzle of each one-diaphragm setter is connected with its blind chamber. EFFECT: increased number of frequencies and extended field of application. 3 cl, 1 dwg
