Abstract (en)

[origin: WO9843780A1] A device for compressing the compression spring of disk valves in motor cylinder heads comprises a C-shaped arch part (4) with an abutment (6) and a movable pressing means (5). Further, the device comprises a stand (1) with on one hand a carrier (2) for the cylinder head, and on the other hand a guide (7) along which a holder (9) is reciprocally movable, with which holder the arch part (4) is connected via at least two vertically separated, thin and wide spring leaves (12, 12'), which on one hand are flexible upwards and downwards due to their small thickness, in order to enable a movement of the arch part between different vertical positions, and on the other hand are rigid laterally due to their width, in order to prevent the arch part from skewing laterally relative to the holder.
