ABSTRACT A hydrodynamic power transmitting construction, such as a clutch, has a pump-wheel connected with the axle of a driving machine, a turbine- wheel connected with the axle of a working machine and a closed working space for these and the working liquid. An axle sleeve fixed to the turbine-wheel is carried in bearings provided with protecting packing. The space between the working space and the packing is connected to an - atmospheric or other - buffer space, the pressure of which in any working condition is less than or equal to the pressure causing a pressure decrease through the bearing. Con- sidering the changes in the physical characteristics due to possible irregular temperatures during working the construction has at least one protection fitting, comprising a threaded pin arranged in a space communicating with atmospheric space and projecting into the vicinity of the rotation axis of the power transmission construction. In this pin a well-known cracking disc is arranged, and operates to fracture, and relieve overpressure in the closed working space.
