<p>The jet-protection sleeve for injectors has at the end in which the injector is inserted two angular slots (2). With the two lugs on the injector these form a bayonet coupling. The sleeve can have a plastics portion (3) enclosed by a lead cylinder (4) near the column of liq. from the injector. A collar (7) at the end furthest from the slot is of the same external dia. as the lead cylinder, which lies against it. The collar can be arranged to unscrew, allowing lead cylinders of different wall thicknesses to be fitted.</p> |
