<p>A thermal pulser is used for converting low-quality thermal energy in a fluid into high-energy pulses. The pulser comprises a chamber (1) which is divided in a fluid-tight manner by a member (3) yielding to pressure and which on the respective side of the pressure-yielding member has an inlet (1a') for a high-energy fluid whose energy content should be converted, and an outlet (1b') for a fluid having a lower energy content, said inlet and outlet being subjected to the influence of a valve device (11) for switching the inlet and outlet functions, the pressure-yielding member (3) communicating with a pressure accumulator (6) which is adapted in response to a fluid pressure increase on one side of the member (3) to build up, against the action of a bias (9c), a predetermined quantity of energy on the other side of the member (3) and, by suppression of the bias, to release said quantity of energy as a short energy pulse.</p> |
