Vatskereglerad manovreringsanordning. 17ppfinnare: J. Rodway. Water-regulated maneuvering device. Inventor: J. Rodway.

Foreliggande uppfinning avser en vatsketryckreglerad manovreringsanordning med ett par med kolvar forsedda cylindrar, som var och en aro anslutna till en tryckfluidumkalla och var f Sr sig forenade med anordningar fbr att astadkomma vridningsrorelse i motsatta rildningar hos en manOveraxel. The present invention relates to a liquid pressure controlled actuator with a pair of piston cylinders, each of which is connected to a pressurized fluid source and is associated with means for effecting rotational motion in opposite turns of a maneuvering shaft.

Uppfinningen utmarker sig i huvudsak av en kolv, som är rorlig i en till tryckfluidumkallan ansluten cylinder, och som är anordnad att paverka ett med manoveraxeln forbundet bromsorgan, i andamal att mojlig b - aOra att manoveraxeln blir automatiskt frigjord, nar en av de hada manOvercylindrarna tillfores tryckfluidum for att astadkomma rorelse av manOveraxeln, och automatiskt bromsad, nar tryckfluidumtillforseln upphor. The invention is essentially characterized by a piston which is movable in a cylinder connected to a pressure fluid, and which is arranged to actuate a braking means connected to the control shaft, in the event that it is possible for the control shaft to be released automatically when one of the control cylinders had pressure fluid is supplied to cause movement of the control shaft, and automatically braked when the pressure fluid supply ceases.

Enligt en sarskild utforingsform av uppfinningen är manovreringsanordningen eller servoreglaget anordnat for avstandsreglering genom att cylindrarna var for sig forenas med en tryckfluidumkalla med -ventiler anbragta i forbindningarna vid avlagsna regleringsstallen fOr att tryckfluidet skall kunna ledas till eller fran cylindrarna. According to a particular embodiment of the invention, the maneuvering device or the servo control is arranged for distance control in that the cylinders are individually combined with a pressure fluid source with valves arranged in the connections at the remote control stalls so that the pressure fluid can be led to or from the cylinders.

Fig. 6 shows a working mechanism from the side and Fig. 7 the same seen from below.

I det visade utforingsexemplet Or uppfinningen tillampad p0. anordningar for att manovrera resp. reglera ett motorspjall eller en ventil. Regleringen sker genom de anordningar av aggregatet, som aro askadliggjorda i fig. 2-7. Fran ett holje eller hus 1 utskjuta tva servocylindrar 2 och 3. Den manuella manovreringen av anordningen kan ske medelst en spak eller ett handtag 4, vilket ar anbragt ph en axel 5, som uppbar en arm 6, fran vii-ken utgar en forbindelseledning 7, som Or forenad med spjfillaxeln. Vridningsrorelsen av axeln 5 framkallar oppnings- och stangningsrorelse av spjallet i den utstrackning, som be-nor av vridningsrorelsen och i en riktning motsvarande vridningsriktningen. For aystandsreglering av spjallet anvandas enligt uppfinningen cylindrarna 2 och 3, som var och en har anordningar for att framkalla vridningsrorelse av axeln 5. Denn.a rorelse astadkommes i en riktning fran en kolv 8 i cylindern 2, vilken kolv .arbetar mot verkan av en fjader 46 och har en kolvstang 9, vars Iran kolven vanda ande medelst en tapp 10 Or vridbar pa en havarm 11, som ar fritt anbragt pa axeln 5. Pa havarmen 11 Or vridbart anordnad en sparrhake 12, vars ena arm 13 är anordnad att komma i ingrepp med en fast anordnad tapp 14, under det att den antha armen Or avsedd att samvcrka med ta.nder 15 pa periferien av en av axeln 5 uppburen skiva 16. En med ena anden pa hayarmen 11 fast Udder 45 anligger mot sparrhaken 12 och stravar att trycka den i en riktning f5r ingrepp i tanderna 15. In the exemplary embodiment Or shown, the invention is applied p0. devices for maneuvering resp. regulate a motor damper or a valve. The control takes place through the devices of the unit, which are damaged in Figs. 2-7. From a housing or housing 1 project two servo cylinders 2 and 3. The manual maneuvering of the device can take place by means of a lever or a handle 4, which is arranged on a shaft 5, which carried an arm 6, from which a connecting line 7 emerges. , which Or united with the javelin shaft. The rotational movement of the shaft 5 induces opening and closing movement of the damper to the extent which is due to the rotational movement and in a direction corresponding to the direction of rotation. For position control of the throttle, according to the invention the cylinders 2 and 3 are used, each of which has devices for inducing rotational movement of the shaft 5. This movement is effected in a direction from a piston 8 in the cylinder 2, which piston acts against the action of a spring 46 and has a piston rod 9, the Iran of which the piston is used by means of a pin 10 Or rotatable on a sea arm 11, which is freely mounted on the shaft 5. On the sea arm 11 Or rotatably arranged a ratchet 12, one arm 13 of which is arranged to come in engagement with a fixedly arranged pin 14, while the receiving arm Or is intended to co-operate with teeth 15 on the periphery of a disc 16 supported by the shaft 5. A udder 45 fixed with one end on the hay arm 11 abuts against the ratchet 12 and efforts to push it in one direction for engagement with the teeth 15.

Motsatt riktade tander 15a Oro anordnade pa skivan 16 i ett lage, diametralt motsatt tanderna 15, och aro avsedda att paverkas av en sparrhake 12a, som an paverkbar fran cylindern 3 genom exakt liknande forbindningar som de i samband med cylindern 2 beskrivna. Opposite teeth 16a are arranged on the disc 16 in a low, diametrically opposite teeth 15, and are intended to be actuated by a ratchet 12a, which can be actuated from the cylinder 3 by exactly similar connections as those described in connection with the cylinder 2.

I det »oppna» eller overksamma laget enligt fig. 2 aro bada sparrhakarna 12, 12a ur ingrepp med skivan 16 genom all armarna 13, 13a Oro paverkbara av tapparna 14. Den genom den ovan beskrivrm anordningen medgivna graden av rOrelse Or begransad darigenom, att anden av resp. kolv kommer till an-slag mot ett ringformigt utsprang eller an-slag 17 pa huset 1. I a.ndamal att rthelse av skivan 16 och spjallet skall forhindras, nar sparrhakarna 12 och 12a aro ur ingrepp med skivan 16, Or en broms anordnad, bestaende av en flans 18 (fig. 4), som Or fast vid axeln 5 och avsedd att komma i kontakt med en 2— — skiva 19 av friktionsmaterial, vilken skiva medelst skruvar 20 dr fast vid en innervagg ph huset 1. Den erforderliga belastningen mellan flansen 18 och friktionsskivan 19 astadkommes genom en cylinder 21, forsedd med en kolv 22 med en spindel 23, som axiellt phverkar ena anden av axeln 5 for att astadkomma en belastning pa dennas ande, n.ar cy- lindern 21 ãr under tryck genom komprime- rad luft frail matningskallan, vilken luft är avsedd att paverka kolvarna i cylindrarna 2 och 3. Detta tryck Or tillrackligt for .att gra axeln 5 styv vid rOrelse, sh' att den icke glappar bakat under verkan av de latta fjadring- arna av spjallet eller under vibration, men den ãr icke styv f8r att kunna manovreras for hand medelst spaken 4, om sa erfordras. In the "open" or inactive layer according to Fig. 2, both the pivot hooks 12, 12a are out of engagement with the disc 16 through all the arms 13, 13a. They can be affected by the pins 14. The degree of movement allowed by the device described above is limited by spirit of resp. piston comes into abutment against an annular projection or abutment 17 on the housing 1. In this case, the movement of the disc 16 and the damper must be prevented when the ratchets 12 and 12a are out of engagement with the disc 16, or a brake is provided. consisting of a flange 18 (Fig. 4), which Or is fixed to the shaft 5 and intended to come into contact with a 2— - disc 19 of friction material, which disc is fixed by means of screws 20 dr to an inner cradle ph the housing 1. The required load between the flange 18 and the friction disc 19 is provided by a cylinder 21, provided with a piston 22 with a spindle 23, which axially acts on one end of the shaft 5 to provide a load on its spirit, when the cylinder 21 is under pressure through compressed air from the feed head, which air is intended to actuate the pistons in cylinders 2 and 3. This pressure is sufficient to make the shaft 5 rigid in motion, so that it does not loosen baked under the action of the light springs of the damper or under vibration, but the ã is not rigid to be able to be maneuvered by hand by means of the lever 4, if required.

Fig. 3 visar ett lage av anordningen, vid vil- ken kolven 8 har paverkats f8r att forflytta skivan 16 ett tandmellanrum, varvid sparr- haken 12a resp. dess arm 13a Mlles i overkhamt lase genom ingrepp mot tillhorande tapp 14. Fig. 3 shows a layer of the device, at which the piston 8 has been actuated to move the disc 16 a tooth gap, the ratchet hook 12a resp. its arm 13a Mlles in overkhamt lase by engaging the associated pin 14.

For att anordningen skall latt fungera under belastning, d. v. s. nar den paverkas frau avstand, kan till den undre sidan av kolven 22 rnatas komprimerad luft direkt frail endera av servocylindrarna 2 eller 3 genom en omkastningsventil av liten dimension, varvid det framkallade trycket stravar att motverka eller upphava luftens tryck i den yttre anden av cylindern 21. Ornkastningsventilen är i detalj visad i fig. 5 och har en eylindrisk kanal 24 med en grenledning 25, som gar till den undre sidan av kolven 22, Inuti kanalen 24 Or anbragt en ventil 26, bildad av ett metallstycke foretradesvis hrons och forsedd med ett plant sate av syntetiskt gummi, som Or fast pa lampligt satt i en urtagning i varje ande. In order for the device to operate under load, i.e. when it is actuated from a distance, compressed air can be discharged to the lower side of the piston 22 directly from either of the servo cylinders 2 or 3 through a small dimension reversing valve, the pressure developed trying to counteract or raise the pressure of the air in the outer spirit of the cylinder 21. The bounce valve is shown in detail in Fig. 5 and has a cylindrical channel 24 with a branch line 25, which goes to the lower side of the piston 22. Inside the duct 24 Or arranged a valve 26, formed from a piece of metal preferably rhombus and provided with a flat set of synthetic rubber, which Or fixedly fitted in a recess in each spirit.

I fig. 5 Or ventilen 26 visad i det lOge, den intager, nar cylindern 3 Or i verksamhet. In Fig. 5, the valve 26 is shown in the position it occupies when the cylinder 3 Or is in operation.

Komprinnerad luft frau regleringsstallet till- likes cylindern genom en bussning 27 (fig. 6). Den komprimerade luften passerar via en led- ning 28 till kanalen 24 och driver ventilen 26 till det i fig. -visade laget, vid vilket den kommer till anliggning mot ett av sina saten, vid 29, och forhindras all lackning till eller frau cylindern genom forbindelseledningen 30. Den genom ledningen 28 strommande komprimerade luften kan emellertid verka genom grenledningen 25 till att forflytta kolven 22 utat i dess cylinder och avlasta axeln 5 for manovrering. Compressed air from the control housing is also applied to the cylinder through a bushing 27 (Fig. 6). The compressed air passes via a line 28 to the duct 24 and drives the valve 26 to the layer shown in Fig., At which it comes into abutment against one of its sets, at 29, and all varnishing to or from the cylinder is prevented by the connecting line 30. However, the compressed air flowing through the line 28 can act through the branch line 25 to move the piston 22 outwards in its cylinder and relieve the shaft 5 for maneuvering.

Forbindelserna far avstandsregleringsandamai visas i fig. 1. I denna angi-ver 31 en f8r- bindelseledning Iran en kalla for komprimerad lufttillforsel, vilken ledning Or uppdelad i Ire ledningar 32, 33 och 34, varvid ledningarna 32 och 33 leda den komprimerade luften till bussningarna 27 i cylindrarna 2 och under det att ledningen 34 leder en strOm av komprimerad luft direkt till anden ay cylin- dern 21, med vilken ledningen 34 Or forenad vid 35 (fig. 4). The connections for distance control are shown in Fig. 1. In this, a connecting line to Iran indicates a cold compressed air supply, which line Or is divided into Irish lines 32, 33 and 34, the lines 32 and 33 directing the compressed air to the bushings. 27 in the cylinders 2 and while the conduit 34 conducts a stream of compressed air directly to the end of the cylinder 21, with which the conduit 34 is joined at 35 (Fig. 4).

Regleringen sker genom tvh ventiler 36, 37 (fig. 1). Den ena av dessa Or visad i sektion och har en spindel 38 med en del N ay forminskad diameter, sh. att nar spindeln.ar nedtryckt, kanalerna 40 och 41 sta i fOrbindelse med varandra, f Or att komprimerad luft skall kunna stromma till den ifragakomma.nde servocylindern. Spindeln 38 utskjuter ovanfOr ventilhuset och Or darstades forsedd med en knapp 42 fOr manuell paverkan samt med en flans 43, mellan vilken flans och det fast anordnade huset en fjader 44 Or anordnad far att hied ora spindeln 38 till det 0 ritningen visade laget, nar knappen 42 Or utlost. Emellertid Or det givet, att denna utforingsform av regleringsventilen endast Or angiven som ett exempel, dO manga andra kanda ventiltyper kunna vara lika lampade for andamalet i fraga, vilkas utformning bestammes av olika forhallanden och omstandigheter. The control takes place through two valves 36, 37 (fig. 1). One of these Or shown in section and has a spindle 38 with a part N ay reduced diameter, sh. that when the spindle is depressed, the ducts 40 and 41 are connected to each other, so that compressed air can flow to the relevant servo cylinder. The spindle 38 projects above the valve body and is instead provided with a button 42 for manual actuation and with a flange 43, between which flange and the fixed housing a spring 44 is arranged to guide the spindle 38 to the position shown in the drawing, when the button 42 Or triggered. However, it is a given that this embodiment of the control valve is only given as an example, as many other known valve types may be equally suitable for the spirit in question, the design of which is determined by different conditions and circumstances.

Nar endera av regleringsventilerna 36 och 37 paverkas, framkallar den genom en av ledningarna 32 och 33 strommande komprimerade luften att endera av kolvarna fOrflyttas at hoger. Under forutsattning att ventilen 36 har paverkats, framkallar kolvrOrelsen en svangningsrorelse hos havarmen 11 i urvisarriktningen omkring axeln 5. Genom denna rorelse frigives sparrhaken 13 fran ingreppet med tappen 14 och kan den under verkan av sin fjader 45 foras till ingrepp med den lampliga tanden ph. skivan. 16, varigenom alltsa havarmen 11 och skivan 16, vilken. senare Or pakilad ph axeln 5, forflyttas som en en-het (fig. 3) for att oppna spjallet till det vinkelforhallande, som motsvarar det tillatliga slaget av kolven 8, begransat ay anslaget eller utsprhnget 17. When either of the control valves 36 and 37 is actuated, the compressed air flowing through one of the lines 32 and 33 causes one of the pistons to be moved to the right. Assuming that the valve 36 has been actuated, the piston movement induces an oscillating movement of the sea arm 11 in the counterclockwise direction about the axis 5. Through this movement the ratchet 13 is released from the engagement with the pin 14 and can be brought into engagement with the suitable tooth ph. the disc. 16, whereby thus the sea arm 11 and the disc 16, which. later Or pakilad ph shaft 5, is moved as a unit (Fig. 3) to open the damper to the angular ratio corresponding to the permissible stroke of the piston 8, limited by the stop or projection 17.

Vid frigivande av mano-verventilen vid regleringsstallet avgar luft frail servoeylindern, och dess kolv 8, kolvstang 9 och havarmen 11 aterga till det kippna» laget under verkan ay fjadern 46, varvid sparrhaken 12 bringas ur ingrepp med den tandforsedda skivan ph grund ay att sparrhaken ater bringas till ingrepp med tappen 14. Darvid blir bromsen 18, 19 verksam for att sakra axeln 5 mot rorelse. DO luften maste avga, innan servokolven kan atervanda till det »oppna) laget, avlagsnas Oven luften fran den undre sidan av kolven 22. Upon release of the control valve at the control stall, air from the servo cylinder, and its piston 8, piston rod 9 and the lever arm 11, return to the tilted action under the action of the spring 46, whereby the ratchet 12 is brought into engagement with the toothed disc ph due to the ratchet brought into engagement with the pin 14. Thereby the brake 18, 19 becomes effective to secure the shaft 5 against movement. DO the air must be released before the servo piston can return to the "open" layer, the oven air is removed from the lower side of the piston 22.

Vid den askadliggjorda konstruktionen Or skivan 16 forsedd med tva tander f Or anvand- ning i varje riktning, d. v. s. den fullstandiga rorelsen av spjallet kan astadkommas i tvh. steg, t. ex. fran tomgangshastighet till halv hastighet och frail denna senare till full has- tighet. Detta fordrar tvh. manovrar hos den ifragakommande regleringsventilen 36 eller 37, varvid den forsta operationen framfor ski-van medelst en tand och darigenom forflyttar spjallet frau tomgangslage till halv has- — —3 tighet, under det att den andra manovern svanger skivan 16 medelst dess andra laud och aven bringar spj Met fran laget med halv hastighet till dylikt riled full hastighet. Likaledes aro tva operationer av den andra regleringsventilen nadvandiga for att paverka den andra servocylindern till att aterfora spjallet till helt stangt lage i tva steg. Det fir givet, att genom att man akar antalet Under pa skivan 16, app araten kan tilldelas varje onskat antal manoversteg mellan overksamt och fullt verksamt lage, varvid antalet steg bestammes av den apparattyp, som skall utsattas for avstandsregleringen. In the ash-damaged structure, the disc 16 is provided with two teeth for use in each direction, i.e. the complete movement of the damper can be achieved in two directions. rose, e.g. from idle speed to half speed and frail this latter to full speed. This requires tvh. maneuvers of the control valve 36 or 37 in question, the first operation in front of the disc by means of a tooth and thereby moving the throttle from idle to half speed, while the second maneuver swings the disc 16 by means of its second sound and also brings sc Met from the team at half speed to such riled full speed. Likewise, two operations of the second control valve are necessary to actuate the second servo cylinder to return the throttle to the fully closed position in two steps. It is a given that by increasing the number of Under on the disk 16, the apparatus can be assigned any desired number of maneuvering steps between idle and fully operative mode, the number of steps being determined by the type of apparatus to be subjected to the distance control.
