  • the solenoid valve is opened for a predetermined period of time and the solenoid inlet nozzle having a determined section, the fuel is thus metered.
  • the seal ensuring the tightness of the solenoid valve-cartridge connection should be changed regularly. Now, it turns out that changing such a joint is a complicated operation which, in practice, is never performed.
  • the invention proposes to facilitate the operation of changing the gasket of the connection between the fuel cartridge and the gas inlet solenoid valve compressed in the device.
  • the invention relates to a coupling for, on the one hand, a nozzle male ejection of a fuel cartridge for supplying compressed gas to a compressed gas fastening apparatus and, secondly, an intake nozzle of a compressed gas inlet device in the apparatus, comprising sealing means for sealing the connection between the two ends, characterized in that, the tip of the compressed gas inlet device being also a male end, the connector comprises a female seal holder arranged to receive the two male end pieces and the sealing means are arranged to extend on both sides of the joint plane of the two male end caps and surround them
  • the invention therefore consists in relocating the seal which is no longer integrated in the intake tip as in the prior art, but carried by a seal holder that can be easily changed at each cartridge change. fuel.
  • the invention relates to a connector for connecting two end pieces, comprising sealing means, characterized in that, the two end pieces being male, it comprises a female seal holder arranged to receive the two male end pieces and the sealing means are arranged to extend on either side of the joint plane of the two male ends.

  • the sealing means may comprise a sleeve-shaped gasket arranged to surround the two male ends.
  • the seal may include an internal gas retention groove.
  • the sealing means may also comprise two O-rings respectively intended to surround the two male ends.

  • a circular lip 21 extends in the extension of the outer cylindrical wall of the cartridge 20, at one end thereof.
  • the solenoid valve 30, of generally cylindrical shape comprises an intake duct 31 communicating, at one of its ends, with an intake nozzle 32, with the interposition of a filter 33, and at its other end with a metering chamber 34.
  • the solenoid valve 30 also comprises an exhaust duct 35, connected at one of its ends to an exhaust nozzle 36 and, at its other end, to the metering chamber 34.
  • intake ducts 31 and exhaust 35 open into the metering chamber 34 respectively by two orifices arranged opposite one another.
  • a spring washer 37 integral with a sealing gasket 38, is mounted inside the metering chamber 34, by introducing its outer peripheral edge into a slot in the inner wall of the chamber 34.
  • the solenoid valve 30 further comprises an electromagnet 39 under which the shutter gasket 38 can move from an intake position to an exhaust position, by slight deformation of the spring washer 37.
  • intake the seal 38 closes the orifice of the exhaust duct 35 while the inlet of the intake duct 31 is disengaged, and in the exhaust position, the seal 38 closes the orifice of the duct intake 31 while the opening of the exhaust duct 35 is clear.
  • the inlet end 32 of the solenoid valve is a male end surrounded by a sleeve here providing four lateral slots and intended to receive a chimney 3 of the coupling, as will be explained below.
  • the coupling comprises a female seal holder 1 intended to receive the male ejection nozzle 23 of the fuel cartridge 20 and the male intake tip 32 of the solenoid valve 30.
  • the seal holder 1, monobloc and plastic comprises a flat support base 2, here substantially rectangular, supporting the chimney 3 housing a seal 11, open at both ends and extending the along an axis 15 perpendicular to the support base 2, on one side thereof.
  • the free end edge 4 of the chimney 3 is folded at right angles towards the inside of the chimney 3 and forms an opening for the passage of the intake end piece 32 of the solenoid valve 30, having a section substantially equal to that of the tip 32.
  • the spacing between the two legs 5, 6 is substantially equal to the inside diameter of the lip 21 of the fuel cartridge 20.
  • the two legs 5, 6 are each provided, at their free end, with a hook intended to hook onto the inner wall of the lip 21.
  • the support base 2 comprises two pairs of support fingers 7-10, extending in the plane of the base 2.
  • the two fingers 7-8 (9-10) of each pair are located on both sides. other of the connecting end of one of the legs 5, (6) with the base 2, beyond the plane in which the leg 5 (6) extends with respect to the axis 15.
  • the seal 11 housed in the chimney 3 here has a sleeve shape and has an internal groove 12 for retention of leakage gas.
  • the seal 11 is locked between the free end of the flanged end 4 of the chimney 3 and a retaining ring 13 introduced into the chimney 3 through its opening through the support base 2.
  • the retaining ring 13 comprises an inner wall 14 having a frustoconical portion flaring outwardly of the chimney, intended to facilitate the guiding of the ejection nozzle 23 of the fuel cartridge 20 when introduced into the chimney 3, and another portion 14 ', adjacent to the gasket 11, of cylindrical shape, with a section substantially equal to that of the ejection nozzle 23, and intended to guide and hold the nozzle 23.
  • the fixing legs 5, 6 are inserted inside the lip 21 of the cartridge 20, until the bearing fingers 7-10 abut against the lip 21.
  • the ring 13 projects slightly out of the chimney 3 and bears against the base 24, thus ensuring the maintenance of the seal 11 in position within the chimney 3.
  • the seal 38 of the solenoid valve 30 is in the intake position. In this position, compressed gas escapes from the fuel cartridge 20 through the ejection nozzle 23, enters the solenoid valve 30 through the intake nozzle 32 and fills the metering chamber 34, after passing through through the filter 33 and in the intake duct 31.
  • the seal 11 seals the connection of the two ends 23, 32. In case of possible gas leakage, it is housed in the internal groove 12 of the seal which, in any case, is of limited volume.
  • the exhaust tip 36 is connected to the combustion chamber.
  • the electromagnet 39 is actuated by the action of which the spring washer 37 is deformed slightly by moving the seal 38 from its intake position to its exhaust position.
  • the gas contained in the metering chamber 34 then escapes towards the exhaust tip 36, through the exhaust duct 35.
  • the electromagnet 39 is stopped and the shutter seal returns to the intake position.
  • the shutter gasket 38 is thus driven in a reciprocating movement between its inlet position and its position. exhaust.
  • the gasket 11 in the form of a sleeve could be replaced by two O-rings 16, 17, respectively intended to surround the two male end pieces 23, 32 and thus to extend on either side of the plane of joint of the two end pieces 32, 33.
  • a spacer piece 18 is inserted between the two seals so as to position them correctly, as shown in FIG. figure 5 .
