In the liquid friction clutch known from DE 27 18 723 A1, an electromagnetic coil is provided, with which the filling and discharging speeds 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. The magnetic flux emanating from the electromagnetic coil must pass through the magnetic material of the water pump and the main part of the shaft and a large air gap pointing 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.

ルギーが大きくなる。 Furthermore, a liquid friction clutch is provided in which the valve controlling the amount of liquid flowing from the storage chamber into the working chamber through an opening in the bulkhead is operated by an electromagnetic coil located outside the housing. It is publicly known (Japanese Unexamined Patent Publication No. 51-86656). This clutch must also be provided with a transmission member that mechanically transmits the operating force of the armature portion provided outside the housing to the valve inside the housing.
The structure is complicated, and since the transmission member must be passed through the housing in a liquid-tight manner, the liquid-tight penetration part is expensive.Furthermore, the use of the transmission member increases the movable mass, and it requires electricity to operate the valve. Energy increases.

In order to solve this problem, the invention provides that the armature part is mounted on the bulkhead together with the valve so as to be axially movable, and that the two first pole pieces formed in the housing part of the clutch housing are connected on one side. 2 on the belt wheel on the other side, opposite the pole part.
one of the second pole pieces is configured as a sleeve-like extension extending from the sheave towards the housing part, and the other pole piece is configured as a sleeve-like extension extending from the sheave towards the housing part. An electromagnetic coil is formed and spaced radially inwardly of the extension, and is inserted between the second pole pieces.

Thus, according to the invention, the armature is mounted axially movably in the housing on the bulkhead together with the valve, and the magnetic flux is controlled by the electromagnetic coil outside the housing, by the magnetic pole pieces on the belt pulley and by the magnetic pole pieces formed in the housing part. Since it is operated through
There is no mechanical transmission member for transmitting force between the electromagnetic coil and the valve, which simplifies the structure of the valve operating mechanism, and since there is no movable mass for transmitting the operating force, there is no mechanical transmission member required for operation. Electrical energy also decreases. Furthermore, the pole piece can be formed in one piece with the housing part and the belt pulley in the molding process, which reduces the number of parts and simplifies production. The electromagnetic coil is inserted between the sleeve-like extension of the sheave and the sleeve-like pole pieces arranged radially spaced inside thereof, so that the axial length of the clutch is increased due to the electromagnetic coil. Not at all.
