Claims
- 1. Apparatus for the thermal and electrical initiation of fire protection devices comprising a housing with a displaceable support member and an abutment means provided therein, blocking means being disposed between said displaceable support member and said abutment means, said displaceable support member being biased against said blocking means in the direction toward said abutment means, said blocking means being responsive to the exceeding of a predetermined temperature for enabling displacement of said displaceable support member for initiating a fire protection device, said abutment means being constructed as a plunger means displaceable within said housing in the direction towards said displaceable support means, and an electrically actuatable compressed-gas-generating igniter means being disposed on the side of the plunger means facing away from said blocking means for producing compressed gas to cause displacement of said plunger means toward said blocking means, said electrically actuatable igniter means including at least one electrical lead extending outwardly from said housing, and further comprising means for sealing at least the housing in the zone of the plunger means and said at least one electrical lead from outside influences.
- 2. Apparatus according to claim 1, wherein said blocking means is responsive to displacement of said plunger means for at least one of changing the shape thereof and removal thereof from the blocking position so as to permit displacement of said displaceable support means in the direction toward said plunger means for initiating a fire protection device.
- 3. Apparatus according to claim 1, further comprising a cap-like locking means for receiving the electrically actuatable igniter means therein, said locking means being connected with said housing so that said at least one electrical lead extends outwardly therefrom, said plunger means having an end portion facing away from the blocking means guided for movement within said locking means.
- 4. Apparatus according to claim 3, wherein said locking means and said housing are cylindrical members and said plunger means is a cylindrical member, said locking means being threadedly secured to said cylindrical housing.
- 5. Apparatus according to claim 1, wherein said plunger means is provided with a cylindrical outer surface having an offset annular shoulder portion, said annular shoulder being supported on a counter surface of said housing in the direction toward said electrically actuatable igniter means.
- 6. Apparatus according to claim 3, wherein said plunger means is provided with a cylindrical outer surface having an offset annular shoulder portion, said locking means being provided with an annular end face disposed within said housing, said annular shoulder of said plunger means being supported on said annular end face of said locking means in the direction toward said electrically actuatable igniter means.
- 7. Apparatus for the thermal and electrical initiation of fire protection devices comprising a housing with a displaceable support member and an abutment means provided therein, blocking means being disposed between said displaceable support member and said abutment means, said displaceable support member being biased against said blocking means in the direction toward said abutment means, said blocking means being responsive to the exceeding of a predetermined temperature for enabling displacement of said displaceable support member for initiating a fire protection device, said abutment means being constructed as a plunger means displaceable within said housing in the direction towards said displaceable support means, and an electrically actuatable compressed-gas-generating igniter means being disposed on the side of the plunger means facing away from said blocking means for producing compressed gas to cause displacement of said plunger means toward said blocking means, a cap-like locking means for receiving the electrically actuatable igniter means therein, said locking means being connected with said housing, said plunger means having an end portion facing away from the blocking means guided for movement within said locking means, said igniter means including at least one electrical lead extending outwardly from one of said housing and said locking means, and further comprising means for sealing at least one of said housing and said locking means in the zone of said plunger means and in the zone of said at least one electrical lead from outside influences.
- 8. Apparatus according to claim 7, wherein said means for sealing includes a sealing ring disposed between a counter surface of at least one of said housing and said locking means and an offset annular shoulder portion of said plunger means for sealing in the zone of said plunger means, and a sealing material disposed in the zone of said at least one electrical lead.
- 9. Apparatus according to claim 8, wherein said sealing material includes a sealing compound within one of the housing and locking means and a hose member extending over at least one of said housing and said locking means in the zone of at least a portion of said at least one electrical lead.
- 10. Apparatus according to claim 1, wherein said blocking means is a container with a fluid filling for destroying the container upon exceeding the predetermined temperature.
- 11. Apparatus according to claim 10, wherein said container is a glass vessel.
- 12. Apparatus according to claim 7, wherein said blocking means is a container with a fluid filling for destroying the container upon exceeding the predetermined temperature.
- 13. Apparatus according to claim 6, wherein said means for sealing includes a sealing ring disposed between the annular end face of said locking means and said annular shoulder portion of said plunger means for sealing in the zone of said plunger means, and a sealing material disposed in the zone of said at least one electrical lead.
- 14. Apparatus according to claim 13, wherein said sealing material includes a sealing compound within one of the housing and locking means and a hose member extending over at least one of said housing and said locking means in the zone of at least a portion of said at least one electrical lead.
- 15. Apparatus according to claim 14, wherein said blocking means is a container with a fluid filling for destroying the container upon exceeding the predetermined temperature.
- 16. Apparatus according to claim 15, wherein said container is a glass vessel.
