Definitions
- the invention relates to an electromagnetically actuated Pilot valves with small nominal widths to be controlled hydraulically Actuated directional valve, in particular proportional directional valve.
- pilot valves on the side of the directional valve housing attach the pilot valves as cartridge assemblies train and parallel to the actuating axis of the control piston screw the directional valve into the directional valve housing and the pilot valves through separate holes in the directional valve housing connect hydraulically to the directional control valve.
- Such Training and arrangement of the pilot valves in the directional control valve housing requires complex production of the connecting holes, especially since they are sealed leak-free and pressure-tight on the outside Need to become.
- the pilot valves are concerned are proportional adjustable throttle valves with only two Connections.
- the object of the invention is therefore to provide training and to arrange the pilot valves on the directional control valve, which an inexpensive manufacture of the directional control valve with pilot valves guaranteed especially in large series production. This is achieved with the features of claim 1.
- 1 is the cast housing of the directional control valve designated, in a through bore 2, a control piston 3 records.
- the control piston is at its end faces 3a, 3b fixed by springs 4, 5 in its starting position shown.
- the Springs are supported with their ends facing away from the control piston on hollow end screws 6, 7.
- the face of the control piston limit control rooms to which control fluid can be applied 8, 9, the channels 10, 11 with the respective exit spaces 12, 13 of the electromagnetically actuated as cartridges trained pilot valves 14, 15 are connected.
- the Pilot valves are designed as pressure control valves and in corresponding recesses 16, 17 screwed into the cast housing 1.
- the control pressure acting in the control rooms 8, 9 shifts the Control piston 3 against the force of the respective spring 4, 5, wherein depending on the direction of displacement of the control piston, the consumer connection duct 20 either with the pump or the tank connection P, T is connected.
- the actuation axes 21, 22 of the pilot valves run parallel to each other and perpendicular to the actuation axis 23 of the control piston 3. This results in a special simple ducting for the supply and discharge of the Control fluid to and from the pilot valves.
- standing connection bores 25 of the pilot valves are on cast channels 26, 27 running parallel to each other Cast housing adapted, the supply channel 26 with the control pressure medium source P1 and the tank channel 27 with the tank T in Connection is established.
- the supply channel is a transverse one channel-shaped recess 30 with the through hole 2 for the control piston 3 connected.
- the control piston 3 is at the junction 3c tapers in a neck shape and therefore points to it Set up a smaller diameter. This results in a control edge 3d, with a corresponding control edge 2d the through hole cooperates.
- the control edge 2d results by extending the through hole to a control room 32, via a connecting channel 31 with the control room 33 of a control piston 34 for a check valve Holding piston 35 for the consumer, not shown communicates.
- the control piston has a blind bore 34a with two radially running bores 34b, 34c, the control chamber 33 of the control piston via the bore 34b with open control edge 3d of the control piston 3 control fluid can be fed from the connecting channel 31 and via the bore 34c acting as a throttle small diameter to Resetting the control piston control fluid from the Control room 33 for the connection to the tank connection T. Room 37 should be displaced.
- the control piston 3 has grooves milled in the control piston formed control edges 3e, 3f, depending on the direction of displacement of the control piston the connection of the holding piston 35 control room 38 connected to the consumer with that associated with the work equipment source P. Control room 39 or with that connected to the tank Establish control room 40.
- actuating one actuating magnet at a time of the pilot valve in question is one of the supplied electrical current corresponding control pressure at the pilot valve 14, 15 set in the control room concerned 8, 9 of the control piston 3 the latter against the force of each opposite spring 4, 5 moves, to the extent that the increasing spring force corresponds to a control pressure.
