1. A method of adjusting pressure in the volume (52) in the vacuum system, the method comprising the following steps: a) determination of the values (4) of the pressure being a measure of pressure in the volume (52) at different times, and the recording of certain pressure values, b) determining a maximum (12) and the minimum value (14) among the recorded pressure values, c) determining the quantity (16) of the difference of maximum (12) and the minimum value (14), g) comparing the magnitude (16) of the difference with a predetermined first limit value and e) activating the pump for pumping Ms dkosti from the volume (52) if the magnitude (16) of the first difference above a predetermined limit znacheniya.2. The method of claim. 1, characterized in that the pressure value is recorded on the principle of First-in-first-out (first in, first out), wherein the record is only a predetermined maximum number of values davleniya.3. A method according to Claim. 1 or 2, characterized in that the maximum value (12), the minimum value (14) and the magnitude (16) of the difference determined at different points in time, wherein steps d) and e) are performed for each certain value the pressure difference. 4. A method according to claim. 3, characterized in that the maximum value (12), the minimum value (14) and the magnitude (16) of the difference is determined at regular time intervals, preferably, after recording each value davleniya.5. A method according to Claim. 1 or 2, characterized in that the pump (56) is deactivated when the magnitude (16) of the difference becomes smaller than the first predetermined limit znacheniya.6. A method according to Claim. 1 or 2, characterized in that the pressure in the volume (52) is increased if value (16) of the difference is less than a second predetermined limit znacheniya.7. A method according to claim 1 or 2, wherein the additional steps of: e.) Calculating the mean value (8)1. Способ регулировки давления в объеме (52) в вакуумной с
