Definitions

  • the invention relates to a pyrotechnic actuator according to the preamble of claim 1.
  • connection bore or the connection channel can be closed by a closure part.
  • the closure member may be, for example, a screw plug or the like, which is removed for the purpose of the test and used again after the test to seal the space acted upon by the amount of gas of the igniter to the outside.
  • Figure 2 shows a second embodiment in the same view
  • channels 8 which connect a chamber 6 receiving the igniter to a chamber 9, of which at least one wall part is formed by the surface of the piston 2 from which the piston rod 7 protrudes.
  • the igniter 6 is there when inserted into an opening in the housing bottom, which faces away from the housing side, which can be reached by the piston rod 7.
  • the housing 1 is designed as a solid body, for example of two half-shells, with a cavity 3 formed therein for receiving the piston 2, wherein the housing body has the channels 8 or bores which surround the gas outlet of the igniter 6 with the surface of the piston facing away from the housing bottom 2 connect.
  • the connection formed, for example, as a plug connection for the igniter 6 is therefore provided on the side facing away from the piston rod 7 housing side.
  • means are again provided to guide the amount of gas liberated upon ignition of the igniter 6 ' to the side of the piston 2 ' from which the piston rod T protrudes.
  • These means are formed by channels 8 ' which connect a detonator 6 ' receiving chamber of the piston 2 ' with a chamber 9 ' , of which at least one wall portion is formed by the surface of the piston 2 ' from which the piston rod T protrudes.
  • the igniter 6 ' is inserted into an opening at the bottom of the piston 2 ' or the flange 15, which faces away from the piston side from which the piston rod T protrudes.
  • the piston 2 'in this case has the channels 8 ' or bores, which connect the gas outlet of the igniter 6 ' with the piston surface from which the piston rod T protrudes.
  • the connection bore 25 'in the bottom of the piston 2' and in the flange 15 is provided, and the channel 26 'also in the piston 2' is arranged.
  • a valve 24, 24' used which is preferably designed as a check valve.
  • the invention is not limited to the embodiment, but in the context of the disclosure often variable. All new, disclosed in the description and / or drawing single and combination features are considered to be erfindungschert- lent.
