Definitions

  • the invention relates to a hydraulic control according to the preamble of claim 1.
  • a generic hydraulic control according to EP 24 66 153 A1 provides for the hydraulic consumer in an open neutral position of the three-position proportional directional slide a floating position in which the load-holding valves are acted upon at their Auf Kunststoffen simultaneously with the same control pressures that are tapped by Druckvor Kunststoffungen the directional slide when both proportional magnets are energized simultaneously and the same.
  • the hydraulic consumer is hydraulically blocked in the open neutral position of the directional slide, that the Auf Kunststoffenstra the load-holding valves remain pressure-relieved and shut off the load-holding valves, the proportional solenoids are not energized.
  • the hydraulic consumer is controlled in one direction or the other, only a load-holding valve is acted upon on its control side with a control pressure, which is tapped from the pressurized working line and relatively high.
  • the simultaneously acting control pressures from the pressure pilot controls of the directional slide should also be relatively high, for example about 60 bar, ie, for which both proportional magnets must be energized at the same time and at the same time relatively strong to maximum. This can lead to inappropriate floatation due to improper heating by the proportional solenoids.
  • a logic element for fluids is known that is equipped to provide a NOT function or an "EQUALITY function" with two different sized spools.
  • a "NEVER-NOCH-function” is achieved.
  • NOT function a fluid connection is released from an inlet to an outlet if there is no control pressure or the control pressure does not exceed a certain size.
  • EQUALITY function a flow connection from the inlet to the outlet is released when a control pressure applied is equal to the inlet pressure.
  • a flow connection from the inlet to the outlet is then released, if neither a first nor a second control pressure is applied.
  • the invention has for its object to provide a hydraulic control that is inexpensive and reliable.
  • the hydraulic control should allow the floating position and the hydraulic blocking of the hydraulic consumer with a cost-effective and small-sized three-position proportional directional slide and simple load-holding valves.
  • the logic element interrupts a pressure transmission between the control pressure supply and the control sides of the load-holding valves.
  • the and logic element is structurally simple and reliable and can be easily integrated into the control pressure circuit of the hydraulic control. Simple load-holding valves can be used. The control behavior is stable and yet sensitive.
  • the same control pressures are set on the control sides of the two load-holding valves and thus the load-holding valves are opened in the same way.
  • unequal control pressures are set on the control sides of the load-holding valves in order to control the load-holding valves differently and / or differently from one another, if appropriate also in the direction control of the hydraulic consumer, and not only in the floating position.
  • This is preferably accomplished via different nozzle populations in the connections and optionally also in discharge lines connected to the connections to the tank.
  • the responsive logic element first receives the high control pressure from the control pressure supply, e.g. about 60 bar, releases, but this control pressure is modulated or reduced on the way to Aufberichtseite.
  • the nozzle assembly for example, a user-specific adjustment of the Auf Kunststoff s and / or maximum Auf Kunststoffrargues each load-holding valve can make.
  • the and logic element is associated with a discharge relief to the tank comprehensive pressure relief at least for the connections to the Auf Kunststoffen the load-holding valves.
  • a discharge relief to the tank comprehensive pressure relief at least for the connections to the Auf Kunststoffe the load-holding valves.
  • About this pressure relief at least the Auf Kunststoffhestra the load-holding valves are relieved, for example, when the hydraulic consumer must be hydraulically blocked, ie the load-holding valves or one must reliably hold a load.
  • the pressure relief is even incorporated into the logic element and so that the logic element in the control pressure circuit fulfills a further function, in which it also provides for the pressure relief when the operating situation requires it.
  • This is effected particularly advantageously by means of a discharge function monitoring, derived from the response of the logic element on the two simultaneously applied control pressure signals slide function in the logic element. For example, if the float position is set, the discharge line is automatically disconnected from the tank.
  • the pressure relief could also take place in another way and separated from the logic element, for example with a nozzle in the discharge line and / or with a relief switching valve, which is deliberately actuated to relieve.
  • a particularly cost-effective and simple limitation has, for example, a screw-adjustable limit stop for the opening stroke of the load-holding valve, which is optionally adjustable from the outside, or a replaceable but built-in limit stop, such as a spacer or a spacer.
  • an unlocking plunger is loaded by spring force in the closing direction of the check valve, and is provided between the actuating piston a relative idle stroke between these limiting coupling. To unlock the check valve, this idle stroke must first be overcome by the other actuating piston.
  • the one actuating piston is a pot piston which can be moved in a first control pressure chamber over a limited stroke and which preferably carries the other one designed as a solid piston, actuating piston axially slidably receives in a limited between the actuating piston second control chamber and contains a Leerhubanschlag for the other actuating piston as a coupling.
  • the other actuating piston ultimately actuates the plunger to unlock the check valve, but only if both actuating pistons are simultaneously acted upon in each case with a control pressure signal in the first and second control pressure chamber.
  • the series arrangement of the actuating piston ensures that when only applying a control pressure, the check valve is not unlocked.
  • a particularly expedient embodiment is characterized by a 2/2-way slide function, which is incorporated for the one actuating piston in the and logic element.
  • This slide function is used to release a pressure relief to the tank when the check valve is not or no longer unlocked.
  • Pressure medium from control pressure lines which must be relieved of pressure in this phase of operation, takes the path via the open slide function through the logic element to the tank.
  • the first control pressure chamber may be provided with a spool bore portion for a spool end of the one actuating piston.
  • the spool bore portion may be bounded by a sealing ring in the axial direction.
  • At this slide bore section of the tank and a discharge relief required for discharge or one side of the check valve are connected. Via the slide function, the discharge line and the tank can be connected or disconnected. In this way, the logic element in a hydraulic control assumes another function.
  • the check valve is acted upon in the reverse direction with control pressure from a control pressure supply to a hydraulic control.
  • the non-return valve is unlocked via both actuating pistons, it connects the control pressure supply with at least one connection to a pressure-dependent operable valve, preferably a load-holding valve openable against spring force in the hydraulic control.
  • a pressure-dependent operable valve preferably a load-holding valve openable against spring force in the hydraulic control.
  • Structurally and manufacturing technically simple and logic element is designed as Einschraubventil that can be used in a block bore.
  • the and logic element can of course be designed in block design as a separate assembly.
  • Fig. 1 In the block diagram of Fig. 1 is of a hydraulic control H, which optionally has a plurality of sections and for the sections together a pump line P, a return line R (to a pump / tank assembly) and to a control pressure supply (not shown) connected control pressure line Z, a section for controlling a double-acting hydraulic consumer V, eg a hydraulic cylinder shown.
  • the control pressure line Z is for example from a (not shown) control pressure pump or via a (not shown) Pressure reducing valve supplied by the pump line P with a substantially constant control pressure of eg about 60 bar, with which a control pressure circuit 10 is fed.
  • the hydraulic consumer V can be connected to at least P, R via working lines A, B and a three-position-way proportional slide W (4/3 slide valve).
  • the directional slide W has two proportional magnets 4, 6, each of which actuate a pressure feedforward control 5, 6 for adjusting a piston slide between three control positions or from a neutral position into two control positions and against the force of a spring arrangement fixing the piston slide in the middle neutral position.
  • pressure feedforward controls 5, 7, for example pressure reducing valves (not shown) are included, which set in accordance with the energization of the respective proportional solenoid 4, 6 on the spool a certain control pressure, which is regulated for example between 0 and about 60 bar.
  • the control pressure acting on the piston slide can be lower than that of the control pressure supply Z even at maximum current supply.
  • the pressure pilot controls 5, 7 are connected via a control line 8 to the control pressure supply.
  • a feed regulator 3 may be provided between the pump line P and the directional slide W.

  • B leads between the load-holding valve 11, 12 and the directional slide W a control line 15 and 16 to a shuttle valve 17 and 18, from which control lines 19 and 20 lead to the Aufberichtier 47, 48.
  • control lines 23, 24 are further connected, which are connected together via a control line 25 to the logic element L and in which a pilot-operated check valve 26 is included.

  • the direction control of the hydraulic consumer V in FIG. 1 to the left is effected by energizing the other proportional magnet 4, so that the load-holding valve 11 is opened by control pressure in the control line 16 tapped off from the working line B.
  • the AND logic element L does not respond, because then only the control line 2 control pressure leads, while the control line 1 is depressurized.

  • a floating position is required for the hydraulic consumer V or the implement operated by it, ie, both admission chambers of the hydraulic consumer V are to be connected to the tank R.
  • the hydraulic control H contains only a three-position directional slide W, this fourth position is still adjustable as a floating position on the open neutral position by both load-holding valves 11, 12 are turned on. This is done by the and logic element L.

  • Only at the same time and in about the same control pressure signals in the control lines 1, 2 adds the And logic element L this control pressure signals and unlocks the check valve 26 so that the control pressure from the control line 9 from the logic element L on the Control line 25, the control lines 23, 24, which then switching switching shuttle valves 17, 18 and the control lines 19, 20 is brought to the Aufberichtbloquest 47, 48, and the load-holding valves 11, 12 als mortt (floating position).
