The pressure loss Δp through a rectangular gap is calculated from the flow Q, the gap-width bg and the 3rd power of the gap-height hg, the overflow length lg of the gap as well as the density ρ and th

Combination of constant pumps comprising n individual pumps that are geometrically tiered such that 2n—1 delivery flow steps are obtained. By enabling and disabling (unpressurised idle circulation) in

Gap between two chambers with different pressures. To prevent leakage either the gap must be designed such that no pressure flow can be produced ( gap seal ) or special elements are used, the seals. I
