Abstract
FIELD: fire-fighting, particularly for spraying liquid during fire extinguishment.SUBSTANCE: sprinkler comprises body with orifice closed with valve, deflector having screw with support, fixing locking member and heat-sensitive member of the deflector. Heat-sensitive member is made of shape-memory material. Deflector has hub with orifice for receiving bush so that bush may perform axial displacement. Hub and bush have two misaligned through slots for receiving heat-sensitive member formed as a wire clamp. Closed clamp end is connected with one end of additional L-shaped heat-sensitive member by means of flexible tie. Another end of additional heat-sensitive member is secured to thrust means.EFFECT: simplified structure along with provision of necessary response speed.4 dwg
through an opening (50). a second intraluminal catheter (60) has an elongated first tubular member (63) and a support means comprising a second elongated tubular member positioned in a body vein.
