Smoothly-operating pressure conversion plant for increasing pressure includes valve interrupting connection to low-pressure source at end positions of low-pressure piston

摘要

At least one pair of pressure converters (3,4) is connected to a control valve (9). Either the piston side of one pressure converter (7) or the piston side of the other pressure converter is subjected to pressure from the low-pressure source (1). A further control valve (11) is arranged between the control valve and low-pressure source. The latter control valve interrupts connection between the low-pressure source and the control valve at end positions of the low-pressure piston (NK).
