Abstract
1. Линейный компрессор по меньшей мере с одним электромагнитом, по меньшей мере с одним колеблющимся телом, которое осциллирующим образом направляется в переменном поле электромагнита, по меньшей мере с одним поршнем, соединенным с колеблющимся телом и возвратно-поступательным образом двигающимся в цилиндре, и со схемой электропитания, служащей для снабжения электромагнита переменным током, отличающийся тем, что содержит датчик, служащий для определения того, уменьшается ли расстояние между поршнем и торцом цилиндра ниже порогового значения или нет, а также схему управления, служащую для определения временного интервала (Δtвкл), в течение которого расстояние между поршнем и торцом уменьшается ниже порогового значения, а также служащую для регулирования амплитуды и/или фазы переменного тока в случае отклонения временного интервала (Δtвкл) от положительного заданного значения. ! 2. Линейный компрессор по п.1, отличающийся тем, что заданное значение меньше, чем , где ε - пороговое значение, Т - период осцилляции поршня, L - расстояние между торцом и поршнем в состоянии покоя поршня. ! 3. Линейный компрессор по п.2, отличающийся тем, что заданное значение меньше, чем 0,15 Т. ! 4. Линейный компрессор по п.2, отличающийся тем, что заданное значение больше, чем 0,02 Т. ! 5. Линейный компрессор по п.1 или 2, отличающийся тем, что пороговое значение меньше, чем одна десятая расстояния между торцом и поршнем в состоянии покоя поршня. ! 6. Линейный компрессор по п.1 или 2, отличающийся тем, что пороговое значение больше, чем одна пятидесятая расстояния между торцом и поршнем в состоянии покоя поршня. ! 7. Линейный компрессор по п.1, отличающийс� 1. Linear compressor with at least one electromagnet, with at least one oscillating body, which is oscillatingly directed in the alternating field of the electromagnet, with at least one piston connected to the oscillating body and reciprocatingly moving in the cylinder, and with a power supply circuit serving to supply the electromagnet with alternating current, characterized in that it contains a sensor that serves to determine whether the distance between the piston and the end of the cylinder decreases below a threshold value or not, as well as a control circuit used to determine the time interval (Δton), during which the distance between the piston and the end decreases below the threshold value, and also serves to regulate the amplitude and / or phase of the alternating current in case of deviation of the time interval (Δt on) from the positive set value. ! 2. Linear compressor according to claim 1, characterized in that the predetermined value is less than, where ε is the threshold value, T is the oscillation period of the piston, L is the distance between the end face and the piston at rest of the piston. ! 3. Linear compressor according to claim 2, characterized in that the set point is less than 0.15 T.! 4. Linear compressor according to claim 2, characterized in that the predetermined value is greater than 0.02 T.! 5. Linear compressor according to claim 1 or 2, characterized in that the threshold value is less than one tenth of the distance between the end face and the piston at rest of the piston. ! 6. Linear compressor according to claim 1 or 2, characterized in that the threshold value is greater than one-fiftieth of the distance between the end face and the piston at rest of the piston. ! 7. A linear compressor according to claim 1, characterized by
