Assembled camshaft for camshaft drive system for actuating charge-cycle valve of internal combustion engine, has piston supported opposite to camshaft insert and directly mounted within pipe for pivoting rotor against stator

摘要

#CMT# #/CMT# The camshaft (5) has a non-return valve, and a swing motor adjuster (1) whose rotor (6) is fitted on a hollow pipe (66) in a torque-proof manner. A piston (33) is supported opposite to a camshaft insert (7) by a helical compression spring and directly mounted within the pipe for pivoting the rotor against a stator in an axial movable manner. Micro-gear teeth are present between the rotor and the pipe. The rotor is pretensioned against the camshaft by a screw joint. The insert is formed as a wall that separates a pressure reservoir (20) from a hydraulic part (2). #CMT#USE : #/CMT# Assembled camshaft for a camshaft drive system for actuating a charge-cycle valve of an internal combustion engine. #CMT#ADVANTAGE : #/CMT# The piston is supported opposite to the camshaft insert by the helical compression spring and directly mounted within the pipe for pivoting the rotor against the stator in an axial movable manner, thus ensuring manufacturing of the camshaft in a cost-effective manner. The utilization of the non-return valve avoids leakage loss at a sealed passage for rotary feedthrough of fluid i.e. engine oil. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial sectional view of a camshaft drive system. 1 : Swing motor adjuster 2 : Hydraulic part 5 : Assembled camshaft 6 : Rotor 7 : Camshaft insert 20 : Pressure reservoir 33 : Piston 66 : Hollow pipe.
