    摘要： A valve core for cooperation with a hydraulic valve sleeve, wherein the core is provided with a plurality of longitudinally extending grooves constructed for cooperation with mating radially inwardly facing grooves in the valve sleeve, wherein the grooves are constructed by a rolling operation in a manner permitting almost limitless variations in exact valve-land contour. The invention deals with the valve core thus constructed and a preferred valve slot configuration, along with a novel method and apparatus for the construction thereof.

    摘要： A method for producing metal parts such as special bolts (20) by means of cold extrusion in pressing dies comprises a first step of cutting to size a metal blank (30) to be modelled with predetermined dimensions, at least one step of cold pressing in a die in order to reduce one or more portions of the blank (30) to predetermined diameters, and a step of cold pressing in a die during which a coupling key (25) is formed on a portion (32) of the blank (30), the lateral surface (36) of the key protruding beyond the lateral surface of this portion (32), with respect to the longitudinal axis of the blank (30). The resulting product can be used in particular as a special bolt for the positive coupling of a mowing machine blade to a rotating plate in order to rotate the blade.

    摘要： A periodically transferring mechanism for a self-drilling screw forming machine includes a gear system and a clutch device which controls the engagement of the contact between the contact member of the clutch device and the hosing mounted on the driven shaft. The clutch device is eccentrically connected to a idle gear which has two times of the number of teeth to the active gear so that the clutch device periodically contacts the hosing. A rating switch device is used to switch the transferring rate of the mechanism from 1:1 mold to 2:1 mold.
