<p>A pivotal slide valve for the temperature-dependent regulation of the through flow of a cooling medium, in which for avoiding friction losses, a slight gap is provided between the sealing surface of the pivotal slide valve member and the sealing surface of the housing. For achieving a complete tightness, the pivotal slide valve member is pressed against the sealing surface of the housing when the cooling medium is cold. This is achieved by a corresponding construction of the valve parts between the temperature-dependent working element and the pivotal slide valve member.</p> |
