ABSTRACT:
The locking cap for fuel tanks is provided with electro-mechanical locking means whereby the cap can be unlocked by remote control. The cap comprises a body member having a lid pivotable thereon. A spring-urged pivotable locking device on said body engages a spindle attached to the underside of the lid to hold the latter in a locked position. A spring-urged locking slider engageable with a stop formed on said locking device is controlled by a pair of pivoted armatures which are articulated to said slider.
On energization of a U-shaped electromagnet attracting the armatures the latter effect disengagement of the slider from the locking device which releases the spindle thus unlocking the lid.
