Abstract: A linear guide having a carrier body that can be moved along a guide track is provided having a brake device with brake shoes acting upon the guide track and a piston which is located in a pressure chamber which can be displaced by a pressure medium in the carrier body. The brake device has a spring acting upon the piston. Pressure plates are provided in the carrier body which are pressed against the brake shoes located on the guide track by the spring when the piston is not being subjected to the pressure medium. This results in a linear guide whose carrier body can be mechanically and reliably locked on the guide track in case of emergencies such as pressure medium outages.

Abstract: A tappet (1) is designed to be coupled for different lifts of at least one gas exchange valve. It comprises an outer annular section (2) which concentrically encloses a circular section (3). Both sections (2, 3) are axially movable relative to each other and are loaded in the region of their bottoms (4, 5) by cams of different lifts. Slides (8, 9, 13) extend in receptions (6a, 6b, 7) of the bottoms (4, 5). The first slide (8) cooperates with locking means (14) which scan a signal track on the opposing cam and, in a response to a lift of the signal track, block or permit a longitudinal movement of the first slide (8), the locking means yielding in their releasing direction under action of force. At the same time, the third slide (9) delimits on its radially outer end face (15), a pressure chamber for hydraulic medium. A displacement of all the slides (8, 9, 13) into their coupled position can be effected through this hydraulic medium.

Abstract: A shiftable clamping-type locking mechanism, includes two track-defining elements and a plurality of clamping members, e.g. rollers or balls, arranged between the tracks of the elements and so spring-biased as to seek a clamped position. The clamping members are shiftable by a control unit from the clamped position into a release position in which the clamping members are liberated from the tracks so that the two elements can be freely moved relative to one another. A coupling unit positively connects the two elements to one another in order to prevent an undesired slip between the elements.
