Abstract

Styreanordning for tallerkenventiler av motorer hvor ventilen (14) søkes holdt i en nøytralstilling i avstand fra ventilsetet (17). Etter å ha blitt beveget bort fra nøytralstillingen ved hjelp av en kraftutøvelsesanordning (2) og deretter bare blir påvirket av fjæranordningen (4), blir ventilen satt i en svingebevegelse om nøytralstillingen mellom en lukket stilling og en åpen stilling. Ifølge oppfinnelsen er kraftutøvelsesanordningen (2) en dobbeltvirkende trykkfluidsylinder, hvis stempel (16) inndeler sylinderen i to sylinderrom (24 resp. 25), hvor tilførsel av et trykkfluid til det første sylinderrom (24) beveger ventilen (14) mot stengt stilling. Sylinderens sylinderdel omfatter en kortslutningskanal (18) som munner ut i det første (24) resp. det annet (25) sylinderrom nær de respektive ender av sylinderrommene (24,25), og som kan bli lukket av stempelet (16) og av en i denne anordnet stengeventil (22). Sylinderen omfatter en innløpskanal (60) som ved hjelp av en omkastbar ventil (36) vekselvis skaffer forbindelse mellom det første sylinderrom (24) og en trykkfluidkilde (32) resp. et fluidreservoar (32), og en innløpskanal (50) som ved hjelp av en omkastbar ventil (34) samtidig vekselvis skaffer forbindelse mellom det annet sylinderrom (25) og fluidreservoaret (32) resp. trykkfluidkilden (30). Innløpskanalene (60,50) munner ut i de respektive sylinderrom (24,25) mellom sylinderrommenes ender og munningene (67,69) for kortslutningskanalen (18).Controller for plate valves of motors in which the valve (14) is sought to be held in a neutral position away from the valve seat (17). After being moved away from the neutral position by means of a force exerting device (2) and then only being actuated by the spring device (4), the valve is set in a pivotal movement about the neutral position between a closed position and an open position. According to the invention, the actuating device (2) is a double-acting pressurized fluid cylinder, the piston (16) dividing the cylinder into two cylinder compartments (24 and 25, respectively), where the supply of a pressurized fluid to the first cylinder compartment (24) moves the valve (14) to the closed position. The cylinder portion of the cylinder comprises a short-circuiting channel (18) which opens into the first (24) and (2) respectively. the second (25) cylinder compartment near the respective ends of the cylinder compartments (24,25) and which may be closed by the piston (16) and by a closing valve (22) arranged therein. The cylinder comprises an inlet duct (60) which alternately provides, by means of a reversible valve (36), a connection between the first cylinder chamber (24) and a pressurized fluid source (32), respectively. a fluid reservoir (32), and an inlet duct (50) which, by means of a reversible valve (34), simultaneously alternately provides connection between the second cylinder chamber (25) and the fluid reservoir (32), respectively. the pressure fluid source (30). The inlet ducts (60.50) open into the respective cylinder compartments (24,25) between the ends of the cylinder compartments and the orifices (67,69) for the short-circuit duct (18).
