Document Type and Number:
Japanese Patent JP2002526699
Kind Code:
A
Abstract:
The invention relates to a closing cylinder comprised of a cylinder core (10) which is rotationally accommodated in a cylinder housing (20), and which has a profiled axial boring (11). An axially parallel roll body (25) is arranged in said closing cylinder and is always guided with a partial cross-section (26) in a radial opening (14) of the cylinder core. According to whether an initial position of rotation or a key rotation exists, the blocking element (25) either runs into an inner groove (24) of the cylinder housing (20) or into a marginal recess (34) of a group of rotating discs (30) which are arranged in a profiled axial boring (11) of the cylinder core (10). In order to increase the useful life of the closing cylinder, the invention provides that a spring element (50; 28, 50') is arranged at least between one of the rotating discs (30) and the cylinder core (10). The spring load resulting therefrom blocks, via a blocking surface provided on the rotating disc (30), the blocking element (25) in the cylinder housing (20) in a manner which prevents rotation. The cylinder core (10) comprises, with the axial section thereof serving to accommodate the rotating discs (30), a radial recess (12; 12') for the spring element, and the recess (12', 12') is connected via a radial slot (54) to the axial boring (11) of the cylinder core (10) which accommodates the rotating discs (30).
