Definitions

  • the invention relates to a solenoid-operated valve, especially hydraulic valve, according to the generic term of claim 1.
  • solenoid-operated hydraulic valves for example in machine tools.
  • the solenoid valves take on the control function of arranged on the machine tools
  • Functional devices for example, are here Transport movements or clamping functions and similar called.
  • the valve has a base body on both sides attached electromagnets with a pistons arranged inside the base body Active connection. Whichever of the two magnets is activated, the Magnetic force of the pistons in one way or another Direction moves and there are flow openings free, through which then, for example Hydraulic fluid in different directions can flow, which in turn the movements the facility mentioned by, for example Piston cylinder units causes.
  • the electromagnets are preferred from a central point an operating device controlled, wherein each of the two magnets via an electrical device connector and what is there electrical connection cable with the control device connected is.
  • FR-A-2 617 565 discloses a valve according to the preamble of claim 1, which on opposite sides of its body each has an electromagnet.
  • To the Electromagnets are pin-like electrical connections arranged perpendicular to the longitudinal extent of the base body, the in recordings of an oil-carrying channel having the connecting plug.
  • Disadvantageous is that the valve has high manufacturing accuracy required to juxtapose the connectors of the Electromagnets with the receptacles of the connector, due to the length tolerances of each Components. Furthermore, maintenance or replacement work on the valve with great effort connected because hydraulic fluid through the oil-carrying channels can leak.
  • the invention has for its object a magnet-actuated Valve of the generic type create that is simple and without big Wiring effort can be installed.
  • the object is achieved by that the connector on two opposite one another Sides with plug contacts, arranged between the electromagnets and -be Fixing the electromagnets on the base body of positioned on axial end faces of the electromagnets, engaging in the plug contacts Contact pins fixed in position and with the electromagnets is electrically connected.
  • a solenoid operated valve in particular Hydraulic valve
  • the two electromagnets has a guided in a base body Can lead pistons to different switching positions, thus connected and controlled via only one cable can be. This ensures that both magnets controlled via a connector can be the one with only one cable with one Operating device is connected.
  • the valve is characterized in particular by a simple and easy to assemble.
  • By the contact pins of the electromagnets will be at their simultaneously create a holder for the connector realized.
  • additional connectors or distributors avoided.
  • the connector is designed as a separate unit and also, preferably above, the base body of the valve is arranged.
  • the separate Training of the connector is advantageous achieved that a pre-wiring with the connection cable and the connector and the solenoid valve to be connected can be completed later.
  • the Connector has integrated light-emitting diodes, which, for example, the current switching state of the Show solenoid valve. This can be achieved that are immediately recognized by an operator can, for example, whether the solenoid valve is in is in an open or closed position, with the magnets on both sides each position must be assigned beforehand.
  • FIG. 1 shows a generally designated 10 schematically shown electromagnetic hydraulic valve.
  • the valve 10 has a base body 12 the laterally opposite electromagnet 14 and 16 are arranged.
  • the valve 10 also has one above the base body 12 with a Connection cable 20 connected connector 18.
  • the connector 18 and the base body 12 have parallel areas and own preferably an identical outer dimension.
  • To the, associated with the electromagnets 14 and 16 End faces of the connector 18 has this Plug contacts 22.
  • Assigned to the plug contacts 22 have the electromagnets 14 and 16 contact pins 24 on.
  • the adjoining the base body 12 End faces 13 of the electromagnets 14 and 16 are extended beyond the base body, see above that the electromagnets 14 and 16 an area 15th have in which the contact pins 24 are arranged are.
  • FIG. 1 shows the valve 10 in the assembled Condition in side cut, with the connector 18 is shown schematically.
  • the electromagnets 14 and 16 are mirror images constructed identically. They have a coil 30 which encloses an anchor 32.
  • the anchor 32 is against the force of a restoring element, preferably a spring 34, movable in the axial direction.
  • the base body 12 of the valve 10 has in its Inside one movably guided in a channel 25 Piston 26.
  • the channel 25 or the piston 26 is aligned thereby with those in the electromagnets 14 and 16 guided anchors 32.
  • the base body 12 also has Inlet and outlet openings 28 and one Connection channel 29 on.
  • the electromagnetic valve has the following function from, with the explanation of the actual Valve action only in the most essential is restricted.
