摘要： A pressure converter is disclosed as having an inner cylinder arranged in an outer cylinder and connected to an end piece of the outer cylinder, and in which a large and a small piston are connected to each other so that the large piston can be displaced in the outer cylinder and the small piston can be displaced in the inner cylinder. The inner cylinder is arranged to tilt relative to the outer cylinder in order to permit misalignment of small piston. In this way difficult and costly machining of the outer cylinder is avoided.

摘要： A cylinder lock and key system. The plugs comprise a housing having a cylindrical bore; and a cylindrical plug which is rotatable and which exhibits a front end and a keyway. The keys comprise a key bow; and a key blade is rotatable about the rotational axis when inserted. The plugs and keys are provided with cooperating stop surfaces for defining the fully inserted position of the keys. At least one first stop surface is in contact with a corresponding second stop surfaces when a key is inserted in the keyway of a lock. At least two first stop surfaces of each key are arranged adjacent each other and at least two second stop surfaces of each lock are arranged adjacent each other, at or in proximity to the keyway. The invention also relates to a cylinder lock and key combination, a key, a key blank and a cylinder lock.

摘要： A key safekeeping device for fitting into a hole in a door, wall or corresponding structure includes a first tubular element (10) that carries a first collar (12) on an outer end thereof. A lock cylinder (14) is detachably fitted to the first tubular element. A second tubular element (20) that carries a second collar (22) is intended for lockable engagement with the first tubular element. At least one of the collars is comprised of a separate ring-shaped part (22) that includes an internal aperture for receiving a blocking means (24) in the form of a bent/curved element that is intended to be fitted into a peripheral groove (20c) in the barrel surface of the second tubular element. The blocking element, which lies hidden in the aperture of the ring-shaped part, cannot therefore be removed when the key safekeeping device is fitted and the lock cylinder is mounted in place. Because the collars can be produced as separate parts, the key safekeeping device can be manufactured from tubing of any appropriate material thickness, therewith minimizing the cutting work required in manufacture. This provides gains with respect to tool costs, material consumption, working time and therewith also in respect of the environment.

摘要： A removable core lock and key device comprises a cylinder housing (3), a cylinder core (10) accommodated in said cylinder housing, and an essentially cylindrical plug (20) rotatably arranged in the core. A blocking pin (28) is provided in the core and is movable between an extended position, wherein it engages a recess in the cylinder housing, and a retracted position. An actuator element (26a, 26c) is controlled by at least one control pin tumbler. With a control key in the lock, the control pin tumbler displaces the actuator element so that it moves the blocking pin with the rotation of said plug. With a user key in said key slot, said pin tumbler is disengaged from the actuator element and the plug is free to rotate. In other positions the control pin tumbler blocks rotation of the plug and actuator element. A simple yet reliable and secure removable core arrangement is provided.

摘要： A removable core lock and key device comprises a cylinder housing (10) and a core (20), which is accommodated in the cylinder housing. An adapter (30) is operatively connected to a bolt (32). The core and the adapter are provided with means of connection (20d, 30d), such as a bayonet joint, so as to selectively prevent withdrawal of the core from the housing. Key actuated engagement elements (28, 30c) are arranged to selectively allow mutual rotation of the adapter and the core so as to disengage the means of connection, thereby allowing withdrawal of the core. A simple yet reliable removable core is thereby provided.
