Abstract:
Method for filling an accumulator space of a hydro-pneumatic pressure amplifier with oil and the design of such a hydro-pneumatic pressure amplifier, in which the accumulator space (9) has a venting bore (25) which, also employable as an overfill safeguard, is controlled by a flow valve (28-33) and which is preferably opened by means of the accumulator piston (11) in the initial position of the latter. When there is incorrect ventilation, the accumulator piston (11) is pushed up to a stop (24) determining its end position, in which, in one embodiment of the invention, a second venting bore (41) can be controlled by it.
