Abstract

Til fjernvising av stillingen til det bevegelige element (7) i en dobbeltvirkende, trykkmedlumpåvirket hydraulisk Innstillingsmotor (6), hvor det til denne er forbundet to styreledninger (A2,B2) for trykkmediuintll- førsel og -bortledning for å påvirke det bevegelige element (7) til bevegelse i en åpneretnlng eller en lukkeretnlng, benyttes en volummåler (3) med en kapasitet passende til innstillingsmotorens (6) slag- volum. De to styreledninger (A2,B2) kan over en flerveisventil (2) koples til henholdsvis en trykk- ledning (P) og en tankledning (T), eller i en nøytral ____________________ stilling begge til tankledningen (T). Volummåleren (3) er koplet på en slik måte til flerveisventilen (2), at den i begge arbeidsstillinger, Innkoples i den med tankledningen (T) forbundne styreledning, mens den avsperres i den nøytrale stilling. De to styre- ledninger er tilsluttet innstillingsmotoren over pilotstyrte kontraventilarrangementer (4), som hver i den nøytrale stilling forhindrer passasje av trykk- medium fra innstillingsmotoren til styreledningene, samtidig med at det i arbeidsstillingen først åpnes for tilbakeføring av trykkmedium til tanken, etter at det i den trykkpåvirkede styreledning er oppbygget et til- strekkelig arbeidstrykk.
