Device, for controlling hydraulic membrane compressor, has control valve with throttle, where increasing differential pressure across throttle, causes control valve to open additional opening

摘要

The device has a control valve (10) with a throttle, which is arranged in a drain in front of an oil overflow valve (9). The control valve is controlled according to the differential pressure across the throttle, so that when the pressure difference increases, the control valve opens an opening, through which an additional oil quantity flows to an oil reservoir.
