DEVICES FOR VENTILE ACCESS, RECEIVING VENTILE ACCESS AND REQUIREMENTS FOR THE DEVICES

摘要

A cover body (2) is revealed for a valve rotating device, comprising a ring-shaped top (4) and a ring-shaped bottom (6),where the upper part (4) and the lower part (6) are axial and can accommodate an axial spring element (24), the upper part (4) and the lower part (6) being connected by at least one connecting part (8), with at least one connecting part (8)on which an introductory position of the axial spring element (24) is placed opposite.A valve rotation device (12) is revealed for internal combustion engines, comprising a ring-shaped base body (22),with multiple one-sided pockets (16), each with a ball (14) and a tangential spring (32), the pockets (16) in the circumferential direction having a variable depth, so that curved trajectories (26) are formed for the balls (14), with the tangential springs (32)Press the balls (14) towards one end of the respective bag (16), one cover body (2) after one of the previous claims,where the axial spring element (24) is ring-shaped and supports a first end of the axial spring element (24) on a ring-shaped impact surface (18) of the base body (22) and a second end of the axial spring element (24) on a surface of the upper part (4), with a surface of the lower part (6),which is turned by the axial spring element (24), is applied to the balls (14), with the balls (14) and the axial spring element (24) overlapping in radial direction.A method for the manufacture of a cover body (2) for a valve twister, comprising punching of a metal sheet (28), having two ring-shaped parts (4, 6) after punching, which are connected by at least one connector piece (8), with the punched metal sheet (30)is transferred by bending into a cover body (2).
