Description

Дл  суммировани  величин, заданных давлени ми, примен ют пневматические суммирующие устройства, содержащие две камеры, разделенные меА5браной со штоком и соединенные с входными и выходными каналами.To summarize the values given by pressures, pneumatic summation devices are used, containing two chambers separated by a membrane with a rod and connected to the input and output channels.

Предлагаемое устройство отличаетс  от известных устройств подобного рода тем, что оно содержит два р да входных патрубков с дроссел ми, причем один из р дов патрубков соединен общим воздухопроводом с одной камерой, а другой р д - с другой камерой, - кроме того, в устройстве имеетс  воздухопровод, соедин ющий с одной из камер выходной канал устройства.The proposed device differs from the known devices of this kind in that it contains two rows of inlet nozzles with throttles, with one of the rows of nozzles connected by a common air duct to one chamber, and the other p to the other chamber, in addition to There is an air duct connecting the output channel of the device to one of the chambers.

Така  конструкци  устройства обеспечивает возможность алгебраического суммировани  р да величин посредством однокаскадного устройства .Such a device design provides the possibility of algebraic summation of a number of values by means of a single-stage device.

На чертеже изображена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.

Устройство содержит пневмосистему, состо щую из двух камер / и 2, разделенных мембраной 3 со штоком 4, и позвол ет осуществл ть операцию суммировани  по формуле:The device contains a pneumatic system consisting of two chambers / and 2, separated by a membrane 3 with a stem 4, and allows the summation operation according to the formula:

Р.,„-- SP,- Е Р,,R., „- SP, - ER,

где: - выходное, а Р и PS - входные давлени .where: - output, and P and PS - input pressure.

Воздух под входными давлени ми PI, Р2,РП через дроссели 5 подаетс  в камеру 1, где давлени  суммируютс . Точность суммировани  обеспечена применением специального компенсационного дроссел  6, дающего проток в атмосферу. Аналогично воздух под входными давлени ми -Р„ + 1 .Рл+2 . . .2/1-1 соответствующи: 1и отрицательным слагаемым, подаетс  через дроссели 7 и компенсационный дроссель 8 в камеру 2. Здесь также происходит суммирование давлений .Air under the inlet pressures PI, P2, RP through chokes 5 is supplied to chamber 1, where the pressures are added up. The accuracy of the summation is ensured by the use of a special compensating throttle 6, which gives a channel to the atmosphere. Similarly, the air under the inlet pressure mi-R + 1. R + 2. . .2 / 1-1 are the corresponding: 1 and the negative term, fed through the throttles 7 and the compensation throttle 8 to chamber 2. Here also the summation of pressures takes place.
