Title:
ELECTRICALLY-DRIVEN PRESSURE REGULATOR- AND VOLUME-DELIVERY UNIT
Document Type and Number:
WIPO Patent Application WO/2015/036623
Kind Code:
A3
Abstract:
The invention relates to a pressure-volume delivery system comprising a piston-cylinder unit with a piston acting on both sides (dual-action reciprocating piston), said piston having at least two different active surfaces in corresponding pressure chambers and the pressure chambers being connected to at least one consumer via hydraulic lines. The delivery system also comprises a drive for the piston-cylinder unit. According to the invention, the pressure chambers and/or hydraulic lines are interconnected by means of at least one or more switching valves connected in parallel and having a large flow cross-section (AV) and via a short hydraulic line or lines with low flow resistance.
