Definitions

  • the invention relates to a 5/3 valve according to the preamble of claim 1.
  • 5/3 valves have five connections (one pressure medium supply connection, two consumer connections and two pressure medium discharge connections) and can take up three switching positions (in the one alternative, the pressure medium supply connection is connected to both consumer connections in the first switching position, in the second switching position only to one consumer connection and in the third switching position only with the other consumer connection; in a second variant, in the first switching position both consumer connections are connected to the associated pressure medium discharge connections, in the second switching position only one consumer connection and in the third switching position only the other consumer connection).
  • the previously known 5/3 valves are designed as slide valves.
  • the control device which is displaceable in the valve housing, contains an elongated valve body which has a plurality of control surfaces and which produces the connections mentioned in the three switching positions.
  • the main disadvantage of these known 5/3 valves, designed as slide valves, is their high manufacturing costs and their relatively short life.
  • the invention is therefore based on the object of developing a 5/3 valve which is distinguished by a particularly simple construction, a long service life and a small space requirement.
  • the invention therefore realizes for the first time a slide valve as a 5/3 valve. It is characterized by a particularly simple and space-saving design, it being of particular importance for the economical production that largely basic elements of known 3/2 valves can be used. Another advantage is the long service life in comparison to slide valves, which can be achieved by designing the valve according to the invention as a slide seat valve.
  • the invention is illustrated in the drawing, for example. 1 and 2 each show a section through an embodiment of the valve according to the invention.
  • the valve housing 1 of the 5/3 valve shown in FIG. 1 contains a central bore 2 into which cross bores 3, 4, 5, 6 and 7 open.
  • the cross bore 3 forms a pressure medium supply connection P
  • the cross bores 4 and 5 are consumers Connections A and B
  • the transverse bores 6 and 7 represent pressure medium discharge connections R and S.
  • the chambers of the bore 2, into which the transverse bores 3 to 7 open, are designated 8 to 12.
  • the bore 2 is closed at both ends by covers 13 and 14, respectively.
  • Another bore 15 running in the longitudinal direction of the valve housing 1 is connected to the chamber 8 through a bore 16 and is closed near its ends by a ball 17, 18 each.
  • the regions 15a, 15b of the bore 15 located outside the balls 17, 18 open into chambers 19, 20.
  • control bodies 21, 21 ⁇ which are of the same design, so that only the control body 21 is described in detail below (the corresponding parts of the control body 21 ⁇ are denoted by the same reference numerals, with the addition of a dash ).
  • the control body 21 carries a one-piece sealing element 22, which forms two sealing surfaces 22a, 22b.
  • the sealing surface 22a interacts with a valve seat 23 and the sealing element 22b with a valve seat 24.
  • control body 21 is connected to a control piston 25, which carries a sealing element 26 on its circumference and is guided so as to slide in the outer region of the bore 2.
  • the inner end 27 of the control body 21 is provided with a bore 27a, into which a guide pin 28 engages in a form-fitting manner but in a slidable manner.
  • a guide pin 28 engages in a form-fitting manner but in a slidable manner.
  • the two control bodies 21, 21 ⁇ are slidably connected at their mutually facing inner ends, so that they can be moved independently of one another.
  • pilot control elements 29, 29 ⁇ which are of the same design, so that the description of the pilot control element 29 is sufficient (here too, corresponding parts of the pilot control element 29 ⁇ are identified by the same reference numerals, with the addition of a dash).
  • the pilot element 29 is a 3/2 valve with three connections and two positions. It contains a movable valve body 31 in a valve housing 30, which can be moved between an upper and lower switching position by means of a magnetic coil 32. In the lower switching position shown in FIG. 1, the valve body 31 closes a bore 34 adjoining the bore 15 with a sealing element 33, while the connection between a bore 35 adjoining the region 15a and a vent bore 36 is released. In the upper switching position, however, a sealing element 37 closes the vent hole 36, while the connection between the holes 34 and 35 is released.
  • the two pilot elements 29, 29 ⁇ are not actuated.
  • the chambers 19, 20 are consequently vented through the holes 35, 36 and 35 ⁇ , 36 ⁇ .
  • the air pressure present in the chambers 8, 9 and 10 presses the two control bodies 21, 21 ⁇ outwards, so that the sealing surfaces 22a, 22 ⁇ a rest sealingly on the valve seats 23, 23 ⁇ .
  • the pressure medium supply connection P is thus connected to the two consumer connections A and B.
  • the control body 21 ⁇ is moved to the left in a corresponding manner by the control piston 25 ⁇ , so that the consumer connection A is shut off from the pressure medium supply connection P and connected to the pressure medium discharge connection R.
  • the basic position of the pilot control elements 29, 29 ⁇ and accordingly the basic position of the control bodies 21, 21 ⁇ is different in FIG. 2.
  • the ventilation bores 36, 36 ⁇ of the pilot control elements 29, 29 ⁇ are closed by the sealing elements 37, 37,, whereas the bores 34, 35 and 34 ⁇ , 35 ⁇ are connected to one another.
  • the chambers 19, 20 are consequently ventilated, so that the control pistons 25, 25 ⁇ push the control bodies 21, 21 ⁇ inwards.
  • the control bodies 21, 21 ⁇ therefore release the connection between the two consumer ports A and B with the associated pressure medium discharge ports R and S.
  • the control body 21 moves to the left out, so that the consumer port B is connected to the pressure medium supply port P.
  • the connection between the consumer connection A and the pressure medium supply connection P is established when the pilot control element 29zuf is actuated.
  • the pressure medium supply to the chambers 19, 20 does not necessarily have to take place via the pilot elements 29 or 29 ⁇ shown, but can also be derived from another controllable pressure medium source.
  • the basic position of the two pilot control elements 29, 29 ⁇ is present, for example, when the solenoid 32 is supplied with current.
  • the pilot control element is then actuated or switched over by a power interruption.
