| abstract |
The invention relates to a constant-pressure storage unit comprising at least one constant-pressure accumulator (A, B, C, D) which is separated into two regions by a displaceable separating piston (11A, 11B, 11C, 11D), at least one liquid pump (9) for conveying a liquid ( 1) and at least one liquid reservoir (4), wherein the constant pressure accumulator (A, B, C, D) on the side on which the area is provided for a liquid, with at least one further container (E), a safety container, keep in touch. This is divided into two regions by a movable separating piston (11E), of which one region is in communication with the at least one constant-pressure accumulator (A, B, C, D) and the liquid pump (9) and the other region is a buffering fluid (5). contains. |
