Abstract
Official abstract text for this publication.
An adjusting device for adjusting valve clearance of a charge-cycle valve of an internal combustion machine is provided. The adjusting device includes a pivoted rocker lever, at one end of which an actuation element is positioned configured to transfer a force to the charge-cycle valve. A transmission element is attached to the actuation element at an opposite end to the charge-cycle valve of which a sleeve area is positioned, which is used to support the transmission element regarding the actuation element. A method for adjusting valve clearance of a charge-cycle valve of an internal combustion machine using an adjusting device is also provided.
First claim
Opening claim text (preview).
The invention claimed is: 1. An adjusting device for a valve clearance of a charge-cycle valve in an internal combustion machine, comprising: a pivoted rocker lever, at one end of which an actuation element is positioned and configured to transfer a force to the charge-cycle valve, and a transmission element is attached to the actuation element at an opposite end to the charge-cycle valve of which a sleeve area is positioned, the sleeve area which is used to support the transmission element with respect to the actuation element, wherein the transmission element has an internal area and an external area, and the internal area has a female thread and the external area has a male thread for supporting the transmission element with respect to the actuation element, and wherein the transmission element uses the female thread with a pre-stressed bolt to support itself at the actuation element, and the transmission element uses the male thread to support itself at a thread of the actuation element. 2. The adjusting device according to claim 1 , wherein the female thread and the male thread of the transmission element each have an identical pitch. 3. A method for adjusting a valve clearance of a charge-cycle valve of an internal combustion machine using an adjusting device comprising a pivoted rocker lever, at one end of which an actuation element is attached and configured to transfer an actuation force to the charge-cycle valve, the method comprising the steps of: attaching a transmission element to the actuation element, wherein the transmission element has an internal area and an external area, attaching a first end portion of a clamping element to the internal area of the transmission element, and bracing the transmission element with the actuation element by applying a torque to the clamping element until a second end portion of the clamping element contacts the actuation element.
