<p>A lock mechanism comprises a housing having a bore therein, a sleeve located within said bore, means for indexing said sleeve within said bore at a selected angular disposition in relation to said sleeve, a rotor which is rotatably mounted and axially slidable within said sleeve, said rotor having a longitudinally extending key slot, pistons slidable within bores in said sleeve and rotor between a first position where said sleeve and rotor are coupled together for simultaneous rotation and a second position on insertion of a key in said slot, and a control element for effecting movement of mechanism to be controlled. The rotor is movable axially from a first position where it is disengaged from said control element and a second position where it drivably engages said control element.</p> |
