Control valve for controlling coolant circuit of internal combustion engine, has sealing element arranged in hole of valve housing such that sealing system of sealing element acts on valve element and/or valve housing

摘要

The valve has feed connections (2) for cooling water of a bypass circuit and a cooler circuit. A sealing element (4) is provided for sealing a coolant flow path in an axial and/or radial direction. The sealing element is arranged in a hole (6) of a valve housing (1) by axial and/or radial pretension such that a sealing system of the sealing element acts on a valve element (3) and/or the valve housing, where the hole is provided as the feed connections. The sealing element is made of sprayable thermoplastic material i.e. polyvinylidene fluoride, and comprises a bellows-like formed part (5).
