    摘要: This invention relates to a device to reduce pulsations on a hydrostatic positive displacement units, such as an axial or radial piston machine working both as a pump and as a motor with a reversible direction of rotation. In the displacement units, at least one piston is mounted so that it can move longitudinally in a cylinder bore which forms a cylinder chamber. The device has a buffer element which is in communication with the high-pressure side and can be brought into connection with the cylinder chamber. The device reduces pulsations on hydrostatic positive displacement units by which the reversing actions of the cylinder chambers are optimized and the pulsations are effectively minimized in a broad bandwidth of operating conditions. A switchable valve, in particular a non-return valve which opens toward the cylinder chamber is located in a connecting channel between the buffer element and the cylinder chamber.

    摘要: A thermally released separation or disconnecting device, particularly for fire protection systems, includes two oppositely arranged joining members which are connected to each other and are subjected to a tensile force. A destructible thermal release element is held between the joining members. The joining members are constructed as stirrups with two legs each, wherein the stirrups equally absorb the tensile force. The destructible thermal release element is held between oppositely arranged legs of the stirrups and extends essentially perpendicularly of the direction of the tensile force in the locked position of the separation device. Each leg of one stirrup holding the thermal release element is connected in the locked position of the separation device to the other leg of the other stirrup in a positively engaging manner against the direction of the tensile force.
