。In the liquid friction clutch known from DE 27187.23, an electromagnetic coil is provided, by means of which the filling speed and the output speed υi of the liquid friction clutch can be controlled. The electromagnetic coil is mounted around the circumference of the water pump shaft, and coaxially to this shaft the armature is mounted on the liquid friction clutch.

てかなりのエネルギーを消費する電磁石コイルを設けね
ばならない。The magnetic flux emanating from the electromagnetic coil must pass through the main part of the magnetic tA diagonal and shaft of the water pump and the large air gap facing towards the armature in order to generate the magnetic field that causes the operating movement of the armature. Such a flux path consumes considerable energy to move the armature, and this energy consumption is due to the lossy flux path. Electromagnetic coils must therefore be provided which consume considerable energy.

本発明の課題は、液体摩擦クラッチの電磁石コイルを、
この液体摩擦クラッチの充填を調整する弁に付属させて
、電磁石コイルに対して最ホのエネルギーで弁を操作で
きるようにすることである。The problem of the present invention is to provide an electromagnetic coil for a liquid friction clutch.
It is attached to a valve that adjusts the filling of this liquid friction clutch so that the valve can be operated with the maximum energy for the electromagnetic coil.

本発明によれば、この課題は特許請求のａ四箇１項の特
徴によって解決される。According to the invention, this problem is solved by the features of subclaim a4.

いる構造部オオは磁界の影響を受けない。In the liquid friction clutch of the invention with regulated filling, the magnetic field is supplied to the valve in the shortest path around the periphery through the pole piece surrounding the electromagnetic coil. Due to this distribution, almost no leakage fields are generated and therefore only a small power electromagnetic coil is required since no further structural parts need to be passed through. The structural part located close to the electromagnetic coil is not affected by the magnetic field.

周知のように自動車用液体摩擦クラッチは全走行時間の
約５％の期間しか必要としないので、本発明によりエネ
ルギーが著しく節約される。Since, as is well known, a liquid friction clutch for a motor vehicle is only required for about 5% of the total driving time, the invention provides significant energy savings.

なぜならば、送風機羽根車の駆動が必要なときにしか電
磁石に電流が流れないからである。This is because current flows through the electromagnet only when it is necessary to drive the blower impeller.

The housing part 8 of the liquid friction clutch 2 is rotatably mounted on the drive flange 16 by means of a bearing 7. The bearing 17 is sealed against the liquid in the working chamber 14 by the sealing piece 18 . The valve 2 is a drive flange, so that the working chamber 14 is empty and can no longer transmit the drive movement of the friction disk 15 to the housing parts 8, 10.
