Definitions

  • the invention is based on a pneumatic directional valve after specified in the preamble of claim 1 Genus.
  • Such a pneumatic directional control valve is already known which is designed as a monostable 5/2 valve, wherein whose longitudinal slide is pilot-controlled by a 3/2 solenoid valve becomes. Switching the longitudinal slide into one Work position is only effective as long as the Magnet in the pilot valve is energized and one Actuating piston with a larger effective diameter Pressure applied. The reset of the longitudinal slide the working position to its stable starting position takes place inevitably after the pilot valve is switched off by an air spring, which includes a return piston with a smaller one effective diameter constantly acted upon by the inlet pressure becomes. The longitudinal slide is thus actuated by a differential piston, the return mechanism for Achievement of a monostable function purely pneumatic is working.
  • FR-A-2 495 269 is also a generic, pilot operated pneumatic changeover valve for known monostable construction, in which the Reset mechanism for the longitudinal slide with Differential piston from a pneumatic spring and from a mechanical spring.
  • This changeover directional valve has the same disadvantages as that Changeover valve described above with pure pneumatic reset mechanism.
  • a pneumatic changeover directional valve known, which is designed as a 5/3 valve.
  • Be Longitudinal slide valve which is sealed by sealing rings fixed to the housing is by a double-acting return device in centered and can be from one double-acting control piston in both directions be deflected.
  • the actuating piston has different sizes effective areas that alternate via two pilot valves are acted upon.
  • This directional valve does not teach monostable design and its control piston can not be as Differential piston drive act.
  • the pneumatic directional valve according to the invention with the has characteristic features of the main claim in contrast, the advantage that it is in such directional valves for a safe switching behavior a lower one Breakaway pressure enables.
  • a lower one Breakaway pressure By releasing the pressure on the return piston during the first phase of the movement of the longitudinal slide this movement already takes place with one lower pressure at the actuating piston.
  • the return piston After The adhesive forces are overcome before the movement begins Longitudinal slide against the correspondingly lower ones required forces of sliding friction and Reset mechanism moved towards working position, the return piston only in the course of the stroke of Longitudinal slide is loaded with pressure. In this way shorter switching times can also be achieved with the monostable Achieve directional valve.
  • this design enables the Directional control valve also has a smaller effective diameter Actuating piston, which is particularly the case with small valves has a favorable effect, in which the longitudinal slide is often only has a diameter of a few millimeters. Further also leads to a smaller stroke volume on the actuating piston a faster pressure reduction and thus a shorter one Switch-back time of the directional valve.
  • the directional valve can be furthermore in a particularly simple and inexpensive manner using existing components produce.
  • Figures 1 and 2 each show one Longitudinal section through a first or second Embodiment in a simplified representation.
  • FIG. 1 shows a longitudinal section through a pneumatic Directional control valve 10, which as a piloted, monostable 5/2 valve is formed.
  • the directional valve 10 has a Valve housing 11 in which a continuous Slider bore 12 a tight and sliding Longitudinal slide 13 picks up.
  • the slide bore 12 are five chambers formed by annular extensions, of which the central one serves as inlet chamber 14 the two sides of which are first (15) and second Consumer chamber (16), while the outside first and second return chamber (17 and 18) themselves connect.
  • These chambers 14 to 18 are in corresponding Way with an inlet port 19, a first and a second Consumer connection 21, 22 and a first or second Return port 23, 24 connected, all in Valve housing 11 are led out downwards.
  • valve housing 11 On the left end face 25 of the valve housing 11 is a Piston housing 26 installed, inside of it Actuating piston 27 arranged for the longitudinal slide 13 is.
  • the piston housing 26 is also by a Intermediate plate (28) closed on the one to Pilot control 3/2 solenoid valve 29 is attached.
  • On its other end face 31 is through the valve housing 11 completed a lid 32.
  • the solenoid valve 29 has a pressure port 33, which a control line 34 with the inlet chamber 14 in Valve housing 11 is connected.
  • a drain port 35 of the solenoid valve 29 is via a drain channel 36 with the first return port 23 in connection.
  • a tax connection 37 of the solenoid valve 29 is with a first pressure chamber 38 in connection, which is formed in the piston housing 26 and from the intermediate plate 28 or the slidably mounted Actuating piston 27 is limited.
  • the actuating piston 27 has a much larger diameter than that Outside diameter of the longitudinal slide 13 and has one for Sealing of the pressure chamber 38 serving lip seal ring 39 on.
  • the longitudinal slide 13 is designed for a 5/2 function and has five piston sections 41 to 45 for this purpose on, at the central third piston section 43 two sealing rings 46 are arranged while the others Piston sections 41, 42 and 44, 45 each have one have similar sealing ring 46.
  • longitudinal slide 13 Between the middle Piston section 43 and the second adjacent to the left Piston section 42, longitudinal slide 13 has a first Ring groove 47 on which in the drawn Starting position of the longitudinal slide 13 of the first Consumer connection 21 with the first return connection 23 connected is.
  • the longitudinal slide 13 between the middle piston section 43 and the adjoining right, fourth piston section 44 has a second annular groove 48 which in the drawn position of the longitudinal slide 13 the inlet connection 19 with the second consumer connection 22 communicates.

  • a control channel 53 which is formed by the Front of the fifth piston section 45 goes out and in the first annular groove 47 opens. In this way he connects the second pressure chamber 51 with the first consumer connection 21.
  • the effective area of the return piston 49 corresponds the outer diameter of the longitudinal slide 13 so that the Reset piston 49 and the actuating piston 27 together form a differential piston, with the help of the Longitudinal slide 13 is deflectable.
  • the operation of the directional valve 10 is as follows explained: The pilot operated, monostable 5/2-way valve 10 is shown in its initial position, which also as Rest position is called.
  • the one used for pilot control Solenoid valve 29 is not energized, thereby Pressure port 33 is blocked. Of that in the inlet connection 19 pressure pending becomes the control pressure supply Via the control line 34 pressure medium branched off, this However, pressure is blocked in the pressure connection 33.
  • the 3/2-way solenoid valve 29 relieves the first Pressure chamber 38 via the control connection 37, the drain connection 35 and the drain channel 36 to the first return port 33.
  • the longitudinal slide 13 is thus only by the force of the Return spring 52 in the drawn starting position held, the second pressure chamber 51 via the control channel 53 has connection to the first consumer connection 21, which in turn in this starting position for the first Return port 23 is relieved. The longitudinal slide 13 is thus stabilized in the drawn starting position.
  • the longitudinal slide 13 from the drawn starting position to the right into a Working position, not shown, are shifted.
  • the pilot valve 29 switched over, the Pressure port 33 is connected to the control port 37, while the connection to the drain port 35 is interrupted becomes.
  • the pressure branched off from the inlet connection 19 can increase now via the control line 34 and the open solenoid valve Build 29 in the first pressure chamber 38, where he on the Actuating piston 27 acts.
  • the force of the actuating piston 27 pushes the longitudinal slide 13 because of its larger size area under pressure compared to the force of the Return piston 49 and the spring 52, of the drawn Starting position in his working position.
  • the first consumer connection 21 is thus alternately depending on the switching position of the Longitudinal slide 13 with the inlet connection 19 or the exhaust air 23 connected.
  • Breakaway pressure also leads to shorter switching times of the Directional control valve 10.
  • This can also be connected to the effective one Diameter of the actuating piston 27 designed smaller become.
  • the smaller stroke volume in the first pressure chamber 38 also enables faster pressure reduction and thus a shorter switch-back time of the valve.
