The invention relates to automatic regulation and can be used in pneumatic automation systems for machines and installations of various purposes.

The purpose of the invention is to increase the accuracy and improve the dynamic characteristics of the controller.

FIG. 1 shows a regulator with a sensing element of a pneumatic sensor in the form of a bellows; in fig. 2 - the same, in the form of a membrane; in fig. 3 - section A-A in FIGS. 1 and 2 (choke, section).

The regulator includes a housing 1 with an inlet 2 and an outlet 3 chambers connected respectively with inlet A and outlet B with chambers between which there is a seat 4 of a podrzhgzhinenny valve 5 placed in the inlet chamber and connected via a rod 6 with a spring-loaded sensing element of the regulator , made in the form of a membrane 7 with a rigid center 8, loaded with a spring 9, equipped with an adjusting screw tO and forming a damping chamber C with the body, separated from the output chamber B by a partition 11 in which the throttle is installed In the form of a split sleeve, the component elements 12 of which are conjugated along diametrical planes and installed with the possibility of radial movement, the outer cylindrical surfaces of the component elements 12 matching with the elastic elements installed in the partition made in the form of plate springs 13. In the hole of the sleeve there are cone

in the form of a set of plates 14 mounted on a movable base 15 connected with a sensitive element 16 of a pneumatic sensor placed in the outlet cavity and forming a measuring chamber D with the housing, which communicates through the opening 17 with the inlet chamber. The sensitive element of the air sensor can be made in the form of

0 bellows, one end of which is bonded to the body, and the other with a movable base 15, or in the form of a membrane fixed in the body: with a rigid center (figure 2), with the movable

 The base 15 is formed by a rigid center of the membrane.

The regulator works in the following way.

With closed output channel 3 in

 the output chamber B the gas pressure increases due to the flow of gas from their input chamber A through the annular gap between the seat 4 and the valve 5. Accordingly, the pressure in the damping chamber increases due to the flow of gas flowing from the output chamber B between the plates 14 through the sleeve 12 into it. in the partition 11. In this case, the diaphragm 7, the stem 6 and the valve 5 move downwards and the valve 5 sits on the seat 4, stopping the passage of gas to output chamber B.

When opening the output channel 3, the gas pressure in chambers B and C decreases due to the flow of gas from chamber C to chamber B through sleeve 12. At this 1.1 membrane 7, rod 6 and valve 5 move upwards. Between the valve 5 and the seat 4, an annular

the gap through which the gas from the inlet chamber A through the bore of the seat 4 enters the outlet chamber B and then through the outlet channel 3 to the consumer.

With increasing gas pressure in the inlet chamber A, it through the opening 17 and the cavity D acts on the sylphon or the membrane 15, and the cone consisting of the plates 14 moves

characteristics of the regulator, it is equipped with a pneumatic sensor placed in the output chamber, and the sensitive element of the pneumatic sensor forms with the body a measuring chamber which communicates with the input gauge, the throttle is made in the form of a split sleeve, the components of which are interconnected along the diametrical planes and mounted with the possibility of radial movement, moreover, the external cylindrical surfaces of the component parts of the split bushing sleeve (throttle) 12, which, having overcome the force of the leaf springs 13, increase the area of the passageway-15 of the coupling with the bushings located in the cross section. When the town decreases, the elastic elements and at the outlet pressure the cone moves upwards, the components of the sleeve are displaced inwards, reducing its passage angle

This reduces the output pressure pulsations.
