Patent DE-19860025-A1 (DE)
Title: Valve timing control for internal combustion engine
Inventor: OGAWA KAZUMI
IPC: F01L1/34
Filed: 1998-12-23
Abstract: The timing of an internal combustion engine is adjusted by a variable phase pulley on the timing belt e.g. on the camshaft. The phase adjustment is via a hydraulic servo inside the pulley and connected to two hydraulic lines. The selected phase is locked by a spring loaded locking peg which is released by hydraulic pressure and which has a drain into the cylinder block. This drains any hydraulic leaks and prevents oiling of the timing belt.
