摘要： The invention relates to a closing cylinder, for motor vehicles in particular, comprising a housing (1). A cylinder core (2) equipped with a blocking channel (22) and spring-loaded tumblers (20,20') is arranged in an inner cylindrical cavity of said housing. When an incorrect key is inserted into the locking channel (22), the blocking protrusions (201) of the tumbler (20,20') engage with a locking groove (13,13') arranged in an element in which the cylinder core (2) is rotatably mounted. When the correct key is inserted, the blocking protusions (201) of the tumblers (20,20') do not go beyond the contour of the cylinder core. Said closing cylinder also has means for coupling the cylinder core (2) with an outlet element (3) when the cylinder core (2) is turned using the correct key and for decoupling the cylinder core (2) from the outlet element (3) of the closing cylinder when the cylinder core (2) is turned using an incorrect key or force. The invention is characterized in that the inner cylindrical cavity of the housing (1) has annular rotatable grooves (11), and in that at least one rib (12), which delimits said annular groove from a side that is located in a direction (o) opposite an axial displacement causing the decoupling of the cylinder core (2) and the outlet element (3), the flanks (130,131) of the blocking grooves extending oin the direction (o) of the axial displacement which causes the decoupling of the cylinder core (2) and the outlet element (3), is interrupted by at least one blocking groove (13), wherein the flanks (130,131) of the blocking grooves extend in the direction (o) of the axial displacement which causes the decoupling of the cylinder core (2) and the outlet element (3).

摘要： Cylinder lock and key combination with a plug (1) rotatably mounted in. a cavity of a cylindrical housing (4), the plug being provided with radial slots (11) arranged in series, each radial slot (11) including two tumblers (2) spring biased in the same direction and provided with side extensions (20) for engagement with a supporting spring, the side extensions (20) being oriented opposite to each other, whereby in certain slots (11) the tumblers (2) are spring biased in one direction and in other slots (11) the tumblers (2) are spring biased in another direction, whereby the tumblers are provided with cord projections (21) protruding into a key channel (10) and engaging corresponding control paths (310, 320, 330, 340) by their control edges (210), the control paths (310. 320, 330, 340) being formed along a longitudinal axis of a key (3) on its wider surfaces, the essential features of which are defined so that the tumblers (2) arranged in series in the odd slots (11) are spring biased in one direction and the tumblers (2) arranged in series in the even slots (11) are spring biased in the opposite direction, whereby their cord projections (21) protrude into the key channel (10) in the direction orthogonal to the sliding motion of the tumblers (2) so that the cord projections (21) are situated in each slot (11) substantially against each other and their lateral control edges (210) adjacent to the side projections (20) cooperate with the control paths (310, 320, 330. 340) formed on the adjacent side walls of the control grooves (31,32, 33, 34) formed in each wider surface of the key (3).
