A gate valve according to the present invention is configured to partition a flow path. The gate valve has a valve box, a valve body, a rotary shaft, a rotation drive unit, a pressing drive unit, a driving pressure generation mechanism, and an energy regeneration mechanism. The rotation drive unit is capable of rotationally driving the valve body. The pressing drive unit is provided in the valve box. The pressing drive unit moves the valve body, in a direction along the flow path, from a valve-opening covering position to a valve closing position at which the valve body contacts the peripheral edge portion, and presses the valve body. The driving pressure generation mechanism is connected to the pressing drive unit and is capable of causing the pressing drive unit to expand and contract. The energy regeneration mechanism regenerates drive energy for valve operation.

A generator with a regeneration device. The electrosurgical generator according to the invention includes an oscillating circuit excited by means of an excitation circuit having a frequency preferably close to its resonant frequency, wherein the oscillation should be periodically interrupted. This can be done, for example, in situations where a pulse-pause modulation of a radio frequency voltage must be created, the fundamental frequency of which, for example, 350 kHz or 500 kHz, can be modulated with a modulation frequency of, for example, 50 kHz. To stop the oscillation in the generator's oscillating circuit as abruptly as possible without losing the energy stored in the oscillating circuit, a regeneration circuit is provided, implemented by means of a voltage multiplier circuit. Compared to a boost converter coupled inductor, it has the advantage of providing a low capacitive load to the oscillating circuit, especially because it is only electrically effectively connected to the oscillating circuit via a switch during the regeneration phase. This concept allows for efficient energy regeneration and therefore allows for precise amplitude modulation of the radio frequency voltage, particularly square wave modulation (on-off-switch).
