Description

Druckübersetzer für hydraulische Drucksysteme. Pressure intensifier for hydraulic pressure systems.

Die Erfindung geht von der Aufgabenstellung aus, einen einfach herstellbaren und einen einfach betreibbaren Druckübersetzer derjenigen Kundschaft (zoBo für Baumaschinen) anbieten zu können die Geräte mit höchstmöglichen Drücken betreiben will9 ZoBo mit Drucken von 400 bis 500 atüO Diese Gelegenheit bietet der Erfindungsgegenstand, der dadurch gekennzeichnet ist, dass er einen oder mehrerer axparlallel zu einem angetriebenen Drehschieber angeordnete, durch Blüssigkeitsdruck axialverschiebbare, und entgegen dieses Druckes federbelastete Differenzkolben aufweist, so dass die Hubräume der kleineren der Kolben in der Hubraumfüllstellung an ein Hochdrucksystem (zoBo an das Drucksystem der grösseren Kolben der Differenzkolben) angeschlossen sind, während die Hubräume der grösseren der Kolben vom Drehschieber im Wechsel an einem Mitteldrucksystem und an einer VorratsbehälterJeibung angesteuert sind0 Die Erf.indungr ha-t folgendes Denken allen Bedenken übergeordnet: a) Es sollen hohe Drücke erzielt werdehO b) Es sollen nur wenige Hauptteile vorhanden sein, nämlich ein Gehäuse, die Differenzkolben und der Drehschieber samt kleinem Antriebsmotor.The invention is based on the object of providing an object that is easy to manufacture and an easily operated pressure intensifier for those customers (zoBo for construction machines) to be able to operate the devices with the highest possible pressures 9 ZoBo with Printing from 400 to 500 atüO This opportunity is offered by the subject of the invention, which is characterized in that it has one or more axparallel to a driven rotary valve, axially displaceable by fluid pressure, and has spring-loaded differential pistons against this pressure, so that the Displacement of the smaller of the pistons in the displacement filling position on a high pressure system (zoBo connected to the pressure system of the larger pistons of the differential pistons) are, while the displacements of the larger of the pistons of the rotary valve alternate are controlled on a medium-pressure system and on a storage tankJeibung0 The invention has put the following thinking above all concerns: a) High pressures should be achieved. B) There should only be a few main parts be, namely a housing, the differential piston and the rotary valve including small Drive motor.

c) Das Gehäuse musss von Bohrwerken einfach aufnehmbar seine Die Zeichnung zeig-t ein zOBo für eine Farbstoffverspritzanlage bekanntes Ausführungsbeispiel in einem Axialschnitt, Der Druckübersetzer ist für einen Hochdruckanschluss an sechs zum Drehschieber 2 konzentrisch angeordnete Uebersetzer- bzw, Differenzkolben 3a, 3b. Diese sieben Teile sind samt Stopfen für die Kolbenkammern axparallel im Gehäuse 1 angeordnet0 Der die Steuerkanäle D auSweisenJe Drehschieber wird von einem Elektromotor gedreht.c) The housing must be easy to pick up by boring mills. The drawing shows a zOBo known embodiment for a dye spraying system in an axial section, the pressure intensifier is for a high pressure connection to six to the rotary valve 2 concentrically arranged transmission or differential piston 3a, 3b. These seven parts, including plugs for the piston chambers, are axparallel in the housing 1 arranged 0 which have the control channels D Each rotary valve is driven by an electric motor turned.

Die Differenzkolben 3a, 3b sind axial beweglich und durch Drcutfedern 11 belastete welche bestrebt sind, die Differenzkolben an die Zapfen 7 der Stopfen 4 anzulegen, 1 sind die Hubräume der Kolben 3a und W die Hubräume der Kolben 3b.The differential pistons 3a, 3b can move axially and are actuated by pressure springs 11 loaded which strive to attach the differential piston to the pin 7 of the stopper 4, 1 are the displacements of pistons 3a and W are the displacements of pistons 3b.

Eines der beiden Lager 5, 6 des Drehschiebers steckt im Verteilerraum Ro Der Verbindungskanal N verhindert diesen Verteilerraum mit dem Raum M, der das Lager 6 enthält und mit dem Mit-teldruck führenden Verteilerkanälen E des Drehschiebers0 Das Gehäuse 1 enthält Rücklaufsicherungen (Rückschlagventile 10 und 1>ruckfedern 11) im Hochdrcukzweig vor dem H@chdruckauslauf H.One of the two bearings 5, 6 of the rotary valve is in the distributor space Ro The connecting duct N prevents this distribution space with the space M, which is the Bearing 6 contains and with the medium pressure leading distribution channels E of the rotary valve 0 The housing 1 contains non-return valves (check valves 10 and 1> return springs 11) in the high pressure branch in front of the high pressure outlet H.

Esbedeutet der Pfeil A der Steuerdruckzuflusss der Pfeil B der Vorratsbehälterabfluss, der Pfeil K den Mitteldruckzulauf und der Pfeil H den Hochdruckzulauf, während R und G Ringräume sind0 Das Steuerdruckmittelsystem besteht demnach aus einer Pumpe, den Räumen D9 A, R9 B9 T und dem Vorratsbehälter, während das Arbeitsdrucksystem einen Kreislauf aus einer Pumpe9 den Räumen K, M, W, H und den und den Arbeitserzeugern vorsieht,The arrow A means the control pressure inflow, the arrow B the reservoir outflow, the arrow K the medium pressure inlet and the arrow H the high pressure inlet, while R and G are annular spaces 0 The control pressure medium system therefore consists of a pump, the rooms D9 A, R9 B9 T and the storage tank, while the working pressure system a circuit from a pump9 the rooms K, M, W, H and the and the work producers provides
