Description

Op'i pfinnelsen vedrører en fremgangsmåte for kontrolleringI !' av trykket i et kammer som inneholder en væske eller et fluidum^i gassform. ] Op'i the invention relates to a method for controlling !' of the pressure in a chamber containing a liquid or a fluid in gaseous form. ]

Kontrollering av trykket hos en væske eller en gass som bI e-<i>' finner seg i et kammer utføres ved å justere et strømnings-tverrsnitt. Størrelsen av dette strømningstverrsnitt er!av-j hengig av trykket for det fluidum som befinner seg i kammer-""i i<1>et og av størrelsen av en justerbar fjærspenning. Et eksem-! pél pa dette er en reduksjonsventil. En ulempe ved denne I „ I i kjente fremgangsmåte er det faktum, at en variasjon av det valgte trykk kun er mulig ved variering av fjærspenningeri. Koi stbare kontrollorganer kreves når denne fremgangsmåte an-vendes i et automatisk kontrollsystem. Controlling the pressure of a liquid or a gas which bI e-<i>' is found in a chamber is carried out by adjusting a flow cross-section. The size of this flow cross-section is dependent on the pressure of the fluid located in the chamber and on the size of an adjustable spring tension. An eczema-! point on this is a reduction valve. A disadvantage of this known method is the fact that a variation of the selected pressure is only possible by variation of the spring tension. Costly control devices are required when this method is used in an automatic control system.

Oppfinnelsen har til formål å redusere ulempene ved den j j kjI ente fremgangsmåten. ■ I denne hensikt omfatter nevnte Jci am-!i mer minst et tilførsels- eller uttømningsorgan, som ofte j vekselvis, åpnes og lukkes. På denne måte kan trykket som j'hersker i kammeret økes eller minskes. Ettersom mengden av ! fluidum pr. tidsenhet kan kontrolleres lettere ved periodisk! å åpne og lukke nevnte tilførsels- eller uttømningsorgan ennj [evtoaFvegirrf I /yd hedmkeekleengen t glaet nikor g gohpsovmnpav nats åriåtvdndeiuæ. d gn ehest ■ kerein e tlffoeøibrg n elrgelvaue lsv akkebr roraiåpepvar pgnansfise jfionrsngn eetnmrerean ygl. v kasnakeÅv egn . t psmnnkeeåsav- ttn rne øotame g nfonvolr eirunnkkgdgkoasenten s vtfmrkeraroeekrn d lvslnvbeerniertislenetgng n ne, ies arvei'■,!, The purpose of the invention is to reduce the disadvantages of the j j kjI ent method.

Denne valgte mengde er den bestemte mengde som krev-j es for frembringelse av denønskede varmemengde for prosessen 1.

This amount per unit of time depends on the measured pressure in the chamber 6 when one has a constant flow cross-. • i In average at the outlet. The pressure in the chamber 6 is determined by the amount of fluid that is supplied to the chamber 6 through the supply device! 5 which is formed by a control body. This control body
