- a negative housing is a receptacle that connects a foreign body with a sensitive element.
- the regulator also contains a bottom made in the form of a disk, which serves as a wall between the low pressure and the damping chamber, and other short-circuited periods; By doing this, the damping camera communicates with a completely low pressure through ⁇ ⁇ 97/28495sky ⁇ / ⁇ 6 / 00286

- the parameter is higher in terms of expression (1), because the higher the maximum pressure, the lower the pressure, the more it is used. This condition is associated with the necessary reduction of the outgoing pressure due to a change in pressure at the inlet of the regulator, which, in turn, increases the volume of the damping chamber. An increase in the volume of the damping camera to ensure stable operation of the regulator will increase the cross-section of the damping gap.
- Parameter ⁇ ) occurs in the denominator of expression (1), because the larger the gas consumption at the outlet of the regulator, the stronger the ejection effect and the smaller the consumption cross-section is to avoid
- the values of the coefficient ⁇ are divided by the experimental way for different ratios ⁇ / ⁇ ⁇ * and are in the range (0.03 ... 1, 93) * 10 l s * m 5 / kg.
- ⁇ coefficient ⁇ ⁇ 0.03 * 10 ⁇ 2 s * m 5 / ⁇ g i.e. Due to insignificant gaps between the connector and the connector, the gas does not accelerate to fill the damping chamber (or to escape from the damping chamber) due to changes in gas the degree of regulation is reduced.
- the values of the coefficient ⁇ g that bind these parameters are divided by an experimental path and are in the range 0.01 ... 0.50.
- ⁇ coefficient ⁇ ⁇ 0.01 ⁇ . e. with insignificant gaps between the plug and the connector, the gas does not accelerate to fill the damper chamber (or to escape from it) due to changes in the gas flow, i.e. Pressure feedback is not provided, resulting in a change in the outlet pressure. The accuracy is reduced by this. ⁇ 97/28495 ⁇ / ⁇ 6 / 00286

- This business area is narrowed down by the direction of the external drive, as well as by the invention.
- the most convenient way is to ensure that high pressure is exerted for the pressure gauge, that is installed, and it is easy to install, and it can be removed.
- the viable option is the performance of the saddle for one whole and the connection is disconnected. With this, the hermeticity of the area of high pressure rises, and the number of regulator parts decreases. In order to reduce the size of the regulator and its metal, it is necessary to use the various free channels in the free-channel environment.
- the membrane of the sensible element is integrally larger, it is slightly smaller.
- the latter is particularly important for the mass production and use of it for the manufacture of other non-ferrous metals.
