 EMI1.1 
 



   An hydraulischen Aufzügen mit elektrischer Steuerung besteht schon bei mittleren Fahrgeschwindigkeiten der Übelstand, dass neben unsanften Abstellgeschwindigkeiten und damit verbundenen   Stössen     hauptsächlich   das Anhalten bei stark wechselnder Belastung ein ungenaues ist. Da der Fahrstuhl immer in der gleichen Entfernung vor der Haltestelle den Abschluss des Steuerschiebers einleitet, jedoch der von diesem Zeitpunkt an von dem   Fahrstuhl   noch zurückgelegte Auslaufweg ganz von den bestehenden Widerständen bezw.

   Belastungen abhängt, so muss er je nach der Belastung verschieden gross ausfallen.   So z.   B. würde bei Vollast der Fahrstuhl nicht ganz bis zur Haltestelle gelangen, während er ohne Belastung um ein entsprechendes   Stück   darüber   hinausfährt.   



   Diesem Umstande zu begegnen, soll nachfolgende neue Ausführung dienen, indem der Abschluss des hydraulischen Steuerapparates nicht auf einmal, sondern in Abstufungen erfolgt, in der Weise, dass ein Mechanismus den vollständigen Abschluss erst zulässt, wenn die Fahrstuhlgesehwindigkeit auf ein geringes   Mass   gebracht ist, bei dem die Geschwindigkeitsdifferenz zwischen Vollast und kleiner Belastung gegen vorher eine bedeutend kleinere wird und so ein   genaueres   Anhalten stattfindet. 



     I)     ir   Zeichnungen stellen ein Ausführungsbeispiel für den Erfindungsgegenstand dar. Die Fig. 1 bis 3 sind achsiale Schnitte, Fig. 4 ist ein Diagramm. 



   Der Steuerschieber S wird von einer Vorsteuerung V aus mittels Druckwassers, Druckluft oder eines sonstigen Betriebsmittels und die Vorsteuerung wiederum durch Schliessen des   Stromkreises für Sreuermagnet 7   vom Fahrstuhlinnern aus betätigt. Vor Ankunft im gewünschten Stockwerke wird der Stromkreis für Steuermagnet 1 wieder unterbrochen, der Hauptsteuerschieber S dadurch umgesteuert, so dass er zurückgeht, aber nur soweit, bis seine Stange an den

 EMI1.1
 



   In hydraulic elevators with electrical control, even at medium travel speeds, there is the disadvantage that, in addition to rough parking speeds and the associated bumps, it is mainly the stopping under strongly changing loads that is an imprecise one. Since the elevator always initiates the completion of the control slide at the same distance in front of the stop, however, the discharge path still covered by the elevator from this point on is completely dependent on the existing resistances respectively.

   Depending on the loads, it must be different in size depending on the load. So z. B. at full load, the elevator would not get all the way to the stop, while it goes beyond it by a corresponding piece without load.



   The following new version is intended to counter this circumstance by closing the hydraulic control apparatus not all at once, but in stages, in such a way that a mechanism only allows complete closure when the elevator speed is brought to a low level where the speed difference between full load and low load compared to the previous one becomes significantly smaller and so a more precise stop takes place.



     I) ir drawings represent an embodiment for the subject of the invention. FIGS. 1 to 3 are axial sections, FIG. 4 is a diagram.



   The control slide S is actuated by a pilot control V by means of pressurized water, compressed air or some other operating medium, and the pilot control in turn is actuated by closing the circuit for Sreuermagnet 7 from inside the elevator. Before arriving at the desired storey, the circuit for control magnet 1 is interrupted again, and the main control spool S is reversed so that it goes back, but only until its rod reaches the
