Hydraulisches Einbauventil, insbesondere für eine hydraulische Nockenwellenverstellung an einem Kraftfahrzeugmotor

摘要

The invention relates to a built-in hydraulic valve, which is specially used for hydraulic camshaft displacement in a motor vehicle engine, comprising a built-in cartridge (10), an actuation device forming a unit with said cartridge (10), specially an electromagnet (13), and a securing eye (27) for fixing the valve to a main housing (9) by means of a screw (29). A valve element (15) can be moved axially in an axial bore hole (14) of the built-in cartridge (13) in order to regulate the hydraulic fluid passage between different external connections of the built-in valve. At least one of said external connections is formed by the radial bore hole (22) in the built-in cartridge (10), which starts at the outer periphery of the built-in cartridge (10) and must be inserted in such a way that it covers a duct of said main housing (9) when the built-in valve is assembled inside the main housing. This is done in a simple manner when the securing eye (27) and the radial bore hole (22) are aligned with each other in such a way that the radial bore hole (22) also covers the duct automatically when the securing eye (27) is positioned in the right place. According to the invention, the angular alignment between the securing eye (27) and the built-in cartridge can only be modified destructively to prevent said alignment from being accidentally changed.
