摘要： A cover body (2) for a valve rotating device includes a ring-shaped upper part (4) and a ring-shaped lower part (6). The upper part (4) and the lower part (6) are axially spaced apart and are adapted to accommodate an axial spring element (24) therebetween. The upper part (4) and the lower part (6) are connected to one another by at least one connecting piece arranged at the location opposite an insertion position of the axial spring element (24).
A valve rotating device (12) having such a cover body is also provided. A ring-shaped base body (22) hasg a plurality of pockets (16) oriented in a circumferential direction, in each of which a ball (14) and a tangential spring (32) are arranged. The pockets (16) have a variable depth in the circumferential direction such that inclined raceways (26) for the balls (14) arranged therein are formed. The tangential springs (32) push the balls (14) toward an end of the respective pocket (16). The axial spring element (24) is ring-shaped and a first end of the axial spring element (24) is supported on an ring-shaped stop surface (18) of the base body (22) and a second end of the axial spring element (24) is supported on a surface of the upper part (4) of the cover. A surface of the lower part (6) facing away from the axial spring element (24) rests against the balls (14), and wherein the balls (14) and the axial spring element (24) are arranged overlapping in the radial direction.
A method for producing a cover body (2) for a valve rotating device is also provided.

摘要： A poppet valve (2) with a valve body (4) has a cavity (6), a coolant inlet port (8). A coolant outlet port (10). The coolant inlet port (8) and the coolant outlet port (10) are arranged on a valve stem (12) of the poppet valve (2). The cavity (6) extends into the valve stem (12) of the poppet valve (2) and into a valve head (14) of the poppet valve (2), wherein there is provided a coolant conducting element (16) within the cavity (6) and extending into the cavity (6) from the valve head (14) to the valve stem (12), where the coolant conducting element (16) in each case has a cross-section. The coolant conducting element (16) includes a pipe section (18) and a funnel section (20), and the coolant conducting element (16) extends concentrically to the poppet valve (2) in the cavity (6) of the poppet valve (2).

摘要： A method for shaping a hollow valve preform of a pull rod (20) includes a structuring bulb (22) which is inserted into the cavity (56) of a shaft portion (44) of a valve preform. The structuring bulb (22) has an outer diameter, and has an outer structuring, whereafter the hollow shaft portion (44) is shaped, wherein at least a portion of an inner diameter of the cavity (56) is reduced below an outer diameter of the structuring bulb (22). The structuring bulb (22) is then pulled out through the shaped shaft portion (44), wherein the outer structuring is at least partially pressed into the surface of the cavity (56).

摘要： A method for producing a magnetic core for an electromagnetic actuator of an electromagnetic valve train includes punching a core blank from a soft magnetic metal sheet and reshaping the core blank. The core blank has a base segment with an opening and a plurality of wall segments that extend outwardly from an outer edge of the base segment. The plurality of wall segments is bent in a direction substantially perpendicular to the base segment during the reshaping.

摘要： A method for the production for a semi-finished valve product (4), includes casting, forging, deep-drawing, pressing and/or drop-welding of one or several metal material into a semi-finished valve product (4) that corresponds to a circle segment of a valve cut open in the axial direction. A valve is produced by welding together at least two semi-finished valve products (4) into an internally cooled valve, with the weld running in the axial direction of the valve.
