Problems solved by technology

The disadvantage that arises in this embodiment is that a large number of parts is required for the thrust bearing of the camshaft
In addition to the higher costs and weight of additional parts this also leads to increased assembly costs
In addition, assembly errors may occur, such as gaskets not being installed inadvertently

Abstract

A device for changing the control times of an internal combustion engine (camshaft adjuster ( 1 )) having a pressure medium distributor ( 21 ) arranged within a camshaft ( 11 ) is provided. The pressure medium distributor ( 21 ) is provided at its front end with a radially extending shoulder ( 42 ), this shoulder ( 42 ) forming part of the camshaft axial mounting.

Description

Camshaft adjuster Technical field The invention relates to a camshaft adjuster for adjusting the phase of the crankshaft of an internal combustion engine and fixing the phase of the camshaft of the internal combustion engine. The camshaft adjuster has a driving wheel driven by the crankshaft and fixed to the driven part of the camshaft, which is installed on the camshaft or cam On the extension of the shaft, it is driven by the driving wheel through a hydraulic actuator, wherein the actuator includes at least a pair of mutually interacting hydraulic pressure chambers and the pressure chamber is supplied with pressure oil through a pressure oil distributor and a pressure oil pipe. Background technique In an internal combustion engine, a camshaft is used to control the gas exchange valve. The camshaft is installed in the internal combustion engine in such a way that the cam mounted on the camshaft is located next to the cam attachment (Nockfolger), where the cam attachment is fo...
