Abstract (en)
[origin: EP0577955A1] The invention relates to a hydropneumatic pressure transformer in which a storage space (9) and a working space (1) with an overflow bore (17) are connected to one another, into which a plunger piston (15) plunges to produce a pressure stage and thereby separates the two spaces and produces a high pressure in the working space (1). According to the invention, an additional connecting passage (19) with a non-return valve (21, 22) is provided.
